Red (!), Yellow (!) and ABS...from washing car?

Hello All,

First time I've had to post on this site...car has been ultra-reliable to this point.

Car just rolled 100km; I decided to change the transaxle fluid, perform an oil change, replace cabin filter, clean the K&N and replace some of the inverter coolant. Most of these services were performed with the car in ramps and the parking brake engaged.

I finished up and took it for a rip; no issues. It was filthy from winter, so I decided to give it a bath.

When I tried to start it up, the dash lit up...red triangle, no PS, red (!), yellow (!) and ABS.

I did some reading and tried to dumped the fault coded with the OBD2 4-13 jumper trick: yellow (!) = 47, ABS = 42. Tried to reset via brake pump 8x/5s, codes come right back.

Pulled the front wheels off, checked the brake pads, ohm'd out the ABS sensors (1.7k each)...I have no clue where to check next.

Car drives fine; the brakes feel weird....much more brake travel, no assist from the motor....very grabby, but still functional.

Any ideas? Something else I should try? All input appreciated!

Thanks,

Fazil

 

Hello,

12V battery was replaced earlier this year; however, I did check it....11.8V when ready.

Thanks,

I stand corrected; 11.8V with no load, 13.4V in Ready.

I have ordered a miniVLC from ebay; I'll send the car into the dealership to have to DTCs pulled. If it's under $500 to get it done, then I'll let them at it....otherwise, I'll bring it home and tackle it.

How much is the factory repair manual? Is changing the brake stoke sensor/skid control ECU DIY? I'm fairly handy with cars, performed all maintenance on every car I have ever owned (timing belts, suspension, brakes).

Thanks for all the input!

Hello,

Yes, 4 qts ws, right from Toyota...torqued both plugs to 29 ft.lbs.

 

Hello,

Did the battery test again last night; 12.1V IG-OFF, 14.1V Ready....too low?

Hello,

Charged the battery; same codes after resetting via 4/13 paperclip.

Dealership can't see me for 3 weeks; the mini vc will be here before then.

In an effort to debug, I've been working through the brake components while leaving the paperclip in 4/13...my theory is that each component I pull should throw a new code...if not, I have my culprit.

Tried removing the connection to the brake battery booster (new to the aux battery), new code. Same as the 4 relays....reset the system using 8/5s trick, pull the relay, check for new code. Checked the fuses and confirmed the fusible link for the ABS is intact via ohm meter to the ABS relay.

Is there a simple way (short of taking it apart) to pull the power from the brake stroke simulator? Where do I find it?

Thanks,

Fazil

 

Finally got Mini-VCI, it's a f/w 1.41 version.

Tried to read DTCs; won't communicate with ABS system...see attachment.

Any ideas?

 

Tried installing the s/w on another laptop, same thing....1/2 ECUs aren't being read....

Figured it had to be something major to take out the canbus, so went old school on it.

I pulled and checked all the fuses under the dash one by one....found the 7.5A for OBD blown. Replaced it, fired up mini VCI, came up without issue. Tried clearing the DTCs, no dice. Did a zero point calibration, cleared DTCs, good to go!!!!!!

Drove it last night, no issues. Might not be out of the woods yet as fuses don't go on their on, but time will tell.

Anyone that does not have a mini VCI should drop what they're doing right now and order one....you cannot work on this car without one. It's AMAZING what this tool can do.

Much thanks for this site, in particular Patrick and JC for the help.

Hi Ed,

Yes, I did; there was some fluid drip from the transaxle fluid change...wanted to clean it up to check for leaks.

Could this be related to the failure?
