INTERMITENT IGNITION PROBLEMS SOME TIMES VEHICLE WONT START,OTHER TIMES IS OK,BEEN TOWED 3 TIMES TO WORKSHOP CAN,T FIND PROBLEM


Need more information on this to diagnose tighter but lets start with the basics. If it is not turning over at all or no clicking sound without accessories coming on then it is an electrical problem. If it is turning over but not starting it is a fuel problem. Post what it is doing specifically. If you are driving and the car all of the sudden dies and wont start but turns over then I would look at the fuel relay.

Abs on vr commodore light stays on solutions


Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

Vsc light and traction control


When the VSC and trac light comes on, Your vehicle enter a fail safe function the ECU rejects any open request from the VSC system and your vehicle operate regardless of ABS,TRAC, and VSC. Having it cleared without corrections will allow the light to come on. If the VSC is seeing a large over steer the VSC and trac light comes on.(even if its under steer).If the ABS ,Trac is correct you will need to seek zero calibration.This is done through the DLC connection in the hood.The easy way to reinitial lize steering angle is done by keeping steering wheel in the straight ahead position (driver window down) disconnect the negative battery, and reconnect , turn key on . The other way is to go to the engine and find the DLC again driver window rolled down steering wheel in the straight ahead position. do not shake the vehicle you must be on a true level ground. No heavy load in the vehicle and no entering the vehicle untill this is complete Turn the key on at this point you will do everything through the window you cannot enter the vehicle.in the hood where the DLC is at you will short pin Ts and CG with a paper clip 4 times repeatedly within 8 seconds. There the VSC will go to zero point.Turn key off (again turn ignition off through the window) make sure you remove the shorting out of Ts and CG. Now your done. 10_13_2011_4_27_16_am.gifFor Rav4 use you DLC 3 its under the driver dash.As for the pin location its on the cover of the DLC 3

Abs and traction control lamps coming on on dash intermitantly can also feel a very slight vibration through the brake pedal when the ignition switched on have had the car put on diagnostic scanner and it...


If the sensor didn't fix the problem, then it's most likely a wiring harness issue. A bad sensor/harness will turn off the ABS & traction control and turn on both ABS and Traction lights. time to troubleshoot the wiring harness for continuity/short between the sensor and the computer.

XK8 ABS FAULT LIGHT COMES ON INTERMITANTLY PLUS TRACTION FAULT SHOWS


Number of possibilities. Most likely culprit is wheel bearings. Have these checked. Big heavy car and wheel bearings do take a hammering on XK and XJ's. Once they go, the wheel speed sensors are out of line with the tracking ring and a fault code is thrown. As the TCS uses the same sensor, this also throws a fault. Next in line is the ABS unit (it's hardly ever the main block, but ECU itself, companies on the net offer rebuilt units. Finally it can be the ABS pump unit - but the fault codes will show if this is the case - or you can pull the pump unit plug out of the ABS unit and see if it has continuity with a multimeter - should be a low number of ohms. 8 times out of 10, it is wheel bearing.
