This should have been one of the first things I checked, I will do this tomorrow

Takes a lot of guesswork out of diagnosing problems.

 

[Vstar_83]

I don't expect anyone to do my homework, but feel free to have a giggle and if any codes to come to mind straight away you're more than welcome to tell me. Much respect

 

[Vstar_83]

I have a happy engine by the looks of things

 

[Vstar_83]

Ok, so I have

ABS - 21,22,24 which are all wheel speed sensors FR FL and RL

AYC - 71 proportional valve stem (short or break)

are these easy fixes or anything to be to concerned about? Thanks everyone.

 

[Vstar_83]

I put in a newer ECU, went to do a test and no lights came up. Has this happened to anyone else?

Mucho gracias.

I have error code 82 Electric Pump Failure on my AYC, What are my options??

 

[whats_doing]

Firstly check if your ayc fuses haven't blown.
Otherwise time to go down the magna LSD route.

I take it this hasn't happened to anyone else?

Make sure you are hooking up the right pins, from the pic you posted on Facebook you have linked 5 & 8.. not 1 & 4.

There's a diagram of the diagnostic connector back near the start of this thread.

Had the Christmas Tree this evening.

Codes are...
ECU
14 -TPS
64
71 - Seeings TCL is turned off in the ROM, this should not be.

AYC
41 -TPS... So TPS, duh.

ABS

52.

So, I'll check the TPS, but what are the other bloody codes?

 

[whats_doing]

Check the tps. However for the others disconnect your battery, go for a drive and then check again. See if they come back.

 

[naughtika]

as mentioned in FB... ECU 64 and ABS 52 are listed in post 1 of this thread.

below are the error codes

64 FR Alternator System Terminal - dunno if it means that it is not charging or 'terminal' is not connected properly

52 OFF relay valve failure or power system failure ABS-ECU - possibly it means your abs system or ecu is faulty.

as what's_doing suggested unplug your battery terminals, disconnect it for 5 minutes and while disconnected turn your lights on to rid of residual current

 

[Grey_Ghost]

For future reference. The voltage regulator went about 1000km later. Those codes were a pre-emptive warning.

Hey Couples,perhaps anyone can tell me what to do with this ayc code after reading
the codes.

There comes
Ayc 31 Steer Sensor (ST-1, ST-2, ST-N) System (break)
Is this any part or sensor ect. and if yes where does it sit or located ?

Many thanks

 

[naughtika]

Colonia, as for the AYC 31 steer sensor, did you have the steering wheel at an angle when you checked for the codes?

i suggest reset the ecu and go from there..

 

[Colonia]

No the steering was straight on. But the car has know wintersleep in the garage and the Accu is out since November. Then i will check the codes again soon.
Thanks

Hi guys, so I decided to registered my second key and I saw that I have some ABS errors, actually quiet a lot, I have:

13 Wheel-Speed Sensor (RR) System (Short or Break)
15 Wheel-Speed Sensor System (Abnormal Signal Output)
21 Wheel-Speed Sensor (FR) System
22 Wheel-Speed Sensor (FL) System
24 Wheel-Speed Sensor (RL) System

but the thing is the ABS light never came up without diagnostic mode and second thing everything seems to work fine, I had couple hard braking and ABS always worked without any problems, I also know that ABS sensors are connected to AYC and this seems to work fine as well, also I had to change AYC fluid recently and I bleed whole system and all work without any problem, any weird noises or bad handling, even AYC bars working the way they should. So any ideas whats going on? Why I can have all those errors in diagnostic mode? Cheers guys
