New Bentley Prius Repair Manual has arrived

Hi Bradlee & Justin,

I'm wondering whether you would be willing to scan and post the table-of-contents pages so that people can see what is included in the 648 pages.
Thanks.

 

No...wait....this thread isn't about the new Bentley Prius??

I thought the Bentley Prius was a cousin of the Rolls Royce Volkswagen seen below.

I mean after seeing the absolute beauty of the Rolls Royce Volkswagen, I'm sure there will be a stampede for the Rolls Royce Prius (pics not included, just visualize it, that's all you need).

I just received my manual and it's what you'd expect from Bentley. Very thorough with tons of illustrations and pictures. The two biggest sections are diagnostics and wiring diagrams (as they should be for the Prius) and I didn't realize this one was a hardcover, which is a bonus!

 

How does the Bentley one compare to the Haynes manual?

 

Bentley supplies actual Factory Repair Style Manuals, they are very good for the do-it yourself people. They go into great detail, they are in the same league are the Helm Inc. Factory Repair Manuals.

The Haynes Manuals are more designed for doing typical maintaince as opposed to repairs.

So consider your intended usage an go from there.

 

Unless you are a professional auto tech, the Bentley is as good as it gets. Very well laid out. Not many references to special tools that you don't have (some are necessary, of course). Hands down 10 X better than Chilton, Haynes, Clymer. Not as difficult to read as the Toyota factory manuals. I have all the Toyota volumes and I still ordered a Bentley to keep in the car for traveling and quick reference.

 

What the heck is MiHG ???

Ain't they got words anymore ????

 

I'm glad that you are happy with your manual. Here are a few suggested tests for its usefulness:

1. It is a common DIY activity to replace engine coolant (and for Prius, the inverter coolant.) What does Bentley say about replacing the engine coolant with respect to the coolant heat recovery thermos; and what is their advice with respect to getting air out of the inverter coolant system?

2. What does Bentley say regarding bleeding brake fluid? Another common DIY activity, which can get the innocent Prius owner into trouble.

3. Regarding the diagnostics section, does Bentley list all of the DTC and INF codes that can be generated (hundreds if not thousands, of possibilities?)

I'm interested in the Bentley manual since you say that it contains wiring diagrams. I have the Toyota repair manual documentation but forgot to download the wiring diagrams...

orderded mine, CAN"T WAIT I"LL LET YOU GUYS KNOW!

i recently found out that you need to be hybrid certified or a shop can be fined 20000 dollars if the person working on it isn't certified!

garbage, if the certification can only be for toyota techs and not for independant small shop techs where i work at.

 

Patirck: Received Haynes last week and Bentley just this Tuesday, June 10th, pre-ordered @ Amozon.com. Bently is approx. 3 to 4 times thicker. Haynes is paperback, some pages barely readable. Looks like they where running out of ink. Quick scan, looks like Haynes addresses maintenance and repairs common to non-hybrids and refers you to trained service personnel in the hybrid areas. Bentley is a hardback, looks very professional, thorough explainations with good pictures. Looks like manufacturer M&R manuals that I have, yea, still have, from other cars. Already used it to trace down Coastal's EV Mod Kit tie-ins. Have an idea for a stealthier install. I'm concerned about exposure to voiding warranty. I don't have the kit or my Prius yet. Only short-coming is they don't show the value of the resistors/loads in the combination cruise control switch located on page 13-91. It's tricky because the combination switch looks like it uses a resistor bridge to provide 1 of 4 different voltages to the ECU for the 4 positions of the cruise control switch. Only way to know for sure is to meter across H14(A)13 the V-violet wire and H14(A)1 the W/B white w/black stripe. It looks like the cancel position is the lowest voltage. Coastal circuit board probably is an electronic switching circuit that only closes on the "cancel" position's voltage, between pin(13) & pin(1), probably with a delay to insure a stable trigger voltageto avoid false actvation. The electronic switch then closes a curcuit between pin(1)gnd & H14(A)27 Coastal's O-orange wire to the EV circuits, not shown in the Bentley U.S. version of the manual. Well to you Q's.

Haynes:
1). See trained technition, 2). Don't do any repairs that require bleeding the brakes. 3). None

Bentley:
1). 1page on how to check Transaxle/Inverter coolant level. 3 detailed pages with pictures on Transaxle/Inverter coolant draining and refilling (without coollng system bleed tool) and 3 (with cooling system bleed tool).
2). 3 1/2 detailed pages with pictures, including one with arrows pointing out the 2 ABS relays 1 & 2 that need to be removed, after being instructed by the scan tool to turn the hybrid system OFF, of course.
3). 68 pages, not all full, with roughly 30 to 50 codes/page. DTC with INF, where applicable, including: definition, detection condition and trouble area.
By the way, I think I could perform steps 1 or 2 following their instructions, albeit with extreme caution and much double checking myself.

Patrick, I have a question for you. I have a ScangaugeII, the Bentley manual referenced the Toyota Scan Tool in the context that you where to "follow it's instructions", in the brake bleeding section. Does this mean that I should have spent the extra $50 for Toyota's scan tool. Is Toyota's scan tool unique to Toyota vehicles or will they work on non-Toyota's.

Hope this helps to give you a feel for the manuals and thank you in advance for any enlightenment on the scan gauge tools.

 

Extra $50. Current Toyota scan tool, TIS Techstream is $8,000.

 

Bentley sent me a copy, and I'm starting to go through it. Looks
pretty thorough, albeit much of it is a photo-enhanced rework
of the Toyota service manuals. There's quite a lot of reprint
of the "new car features" material [also freely available at
autoshop101.com, check it out] in the front.
.
One thing to keep in mind is that the "bleed tool" they reference
for engine and inverter coolant is not the computerized scantool,
it's a widget usually called an "air lift" which uses shop air
and the Bernoulli effect to generate a vacuum on whatever system
it's connected to and try to pull most of the air *out* before
letting any fluid back in. It helps remove a lot of the initial
bubbles or at least make them smaller. The process makes a *lot*
of loud hissing. If you don't have high-pressure air on tap from
a compressor handy, it won't do you any good.
.
The appropriate electronic scantool for actuating various pumps
and valves does *not* cost anywhere near $50. Try two orders of
magnitude above that for the most modern version, a Panasonic
Toughbook loaded with the appropriate software that they call
Techstream. The older tool, the Mastertech 5100, is also
expensive. You can possibly also use a recent version of
Autoenginuity's product which claims to support all the device
actuation stuff for Priuses and my small amount of testing and
listening seems to confirm that, although it's a little squirrely.
.
And whatever that stuff was about being fined for working on a
hybrid system is total bunkum. WHO supposedly issues this
fine? C'mon. Any indy shop can work on these cars with the
right training, just like any other complex system. Someone who
dives right into a high-voltage system without the right training
and protective tools may be subject to the Darwin penalty, but
that's about it.
.
Bentley will likely be at Hybridfest, if you want to come talk
to their people!

Bentley will be there and may also do a special tech session Saturday night at the hotel or possibly Sunday morning at the hotel.

 

Hi Dave,

I appreciate your detailed feedback on Haynes vs. Bentley. It sounds like Haynes is a waste of money while Bentley is a great choice for DIYers who find the Toyota repair manual info to be overkill.

You've already received good feedback about the 4-digit cost of the Toyota diagnostic laptop, so I will limit myself to answering the above question. When the H14 connector of the hybrid vehicle ECU is removed, the resistance from pin 13 to ground is as follows. I've also provided voltages expected on that pin when the connector is in place:

Resistance between CCS (H14-13) - Body ground
Neutral 10 k​

​

W or higher
+RES 210 to 270 W​

-SET 560 to 700 ​

​

W​

CANCEL 1,380 to 1,700 ​

​

W​

ON-OFF button is on Below 1 W

Voltage from CCS (H14-13) - Body ground
Neutral 10 to 14 V
+RES 6.6 to 10.1 V
-SET 4.5 to 7.1 V
CANCEL 2.3 to 4.0 V​

ON-OFF button is on Below 1 V

 

Thanks for the response. That makes a lot more sense. That's what I thought at first until I found the tool below on a google search. I figured it was too good to be true. I was talking about the $50 over the cost of the ScangaugeII. I didn't know if the scan tool below might give me more Prius specific information. I like the ScangaugeII. It's currently monitoring our 2000 Avalon XLS w/107K on it. No trouble codes , yea! Love the Xgauges, especially the HPR horsepower.

It was late last night, actually early this AM. I'm taking back my comment about doing it myself. Haven't done anytime major since we got the 2000 Avalon. I still think it's an excellent reference manual for the novice. But upon further review, I believe much of the Prius maintenance needs to be left to trained/experienced technicions that probably would not do the maintenance themselves without the actual factory manuals and with the expensive specialized tools and equipment required.

No! sorry I wasn't clear. I knew the bleed tool that they referenced wasn't that scan tool. They have a picture of it and that it's a "compressed-air-operated" bleed tool. I was only addressing Patrick's question, by pointing out that they, not only covered the subject, but acknowledged the tool existed, and gave what looked to be, detailed instructions, with and without the tool.

Started out helping my dad rebuild the engine in my '49 Pontiac, straight 8, in 1958. Did a lot of my own maint. over the years, oil, tune-ups, brakes, shocks, struts, electrical, added cruise to our VW Quantum, manual trans., etc. Don't claim to be an expert on anything. Grandfather was a carpenter and cabinet maker. Father a tool and die maker. And I, worked for IBM in field service on everything from the old gray iron to the main frame computers. Believe me, even the vehicles today don't have much over the mechanical monstrosities that I worked on for printers and storages devices before the coming of the memory chip. The "data cell" used magnetic strips ot tape that were place in, and removed from, a spinning drum using a hydrolic system, running at 1500psi and driven by a 5hp motor, timings to 50nsec. Point being, Bentley, Chilton, Haynes and factory manuals have served their purpose over the years. I think the Bentley manual looks like a good "repair and maintenance" manual for a novice as long as you leave the specialized/hybrid area to the trained/skilled/experienced tech. And I think it's clear in the manual what those areas are. As long as you're awake when you read them. Since I'm on the infamous "wait list", I don't know if it will be a 2008 or 2009 or maybe even a 2010 the way it's going. I figured the 2008 Bentley would probably cover the 2009 for anything I would attempt to maintain/repair. Mainly wanted a reference point to evaluate some of the Modifications and accessories available for the Prius.
Buy the way, I have a suggestion for a slight modification to Coastals EV Mod kit that would make it 100% removable, no trace left by the vampire taps.

Thanks again. I really appreciate your responses and advice. Looking forward the the "Prius Experience"

 

Patrick: Thanks for the info. I also have a suggestion for making the Coastal EV Mod 100% removable, no trace left by vampire taps. Remove pin connectors in pos 1 & 13, add taps to the Coastal kit wires with pin connectors on the wires. Add a connector that accepts the removed pins in one side and the coastal kit spades in the other side. plug the new taps back into the H14(A) pos #1 & #13, along with pos #27. Connect the wires removed to the kit spades using the connector. And you have a 100% removable mod. I realize this was brief, but not intended to be a set of instructions. Just enough info for the concept. I'm really leary abound doing anything that could void the warranty.

Thanks again for your info in case I decide to build my own circuit board since some users have posted problems. It may be worth it just to have one in hand for reference and parts. Still need to identify the part#'s for the pin connectors and the H14(A) looks like pin# 1 could be a different sizes than #13 and #27.

 

Hi Dave,

The voltage and resistance amounts that I provided in my earlier post are from the 2005 repair manual. However now that I look at them closer, it appears there is a typo with one table or the other. You would expect that a higher resistance from pin 13 to ground would result in a correspondingly higher voltage.

Hence I advise caution when using that info!

<I tried to edit my earlier post but when I open the edit screen the small font characters appear in Cyrillic font (for some unknown reason) so instead I am posting this additional msg.>

 

Yes! That's what I thought too. It would seem that something is awry Dr. Watson. Perhaps someone else out there could shed some light on the quandry.

Thanks
