Why won't abs light go off error code says pump

Do you mean they are spongy or they quit altogether? If spongy, you probably have very low fluid in the reservoir and you are pumping air into the system (fill the reservoir and try again - however, may need a brake bleed, which is tricky with ABS systems). If the ABS is failing, you should see error codes (using a good code reader that will read the ABS ones). Lastly, your brake master cylinder may need to be replaced.

The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.

1. Remove the ABS fuse to prevent ABS motor burn out.
2. You can still drive your vehicle with the module removed.
3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.

Common Failures:

• ABS Pump Always Running
• Codes: C0265, C0267, C0268
• Pump Motor Circuit trouble code
• Power Relay trouble code
• Valve Relay Trouble code
• Dump Valves (solenoids) trouble codes
• No Communication
• Intermediate power loss

Have the abs removed and checked for operation. If you press the pedal hard enough to produce a skid but it doesn't then the abs is working. Under heavy braking from speed you will get a pulsating feeling in the pedal as the brakes are released and then re applied very quickly. If you are finding that no mater how hard you press there appears to be no assistance to brake then the problem will be in the booster and not the ABS.

the ecu controls the power to the pump and injectors. are you getting error on every test on reader that can be the ignition relay. its in the dash when you turn the key should hear it go click click. if just one click then one side of it has gone. there is the low volt side, ignition interior dash lights etc. high volts is ecu abs, air bags. etc. low volts go to the abs and ecu but when engine started it needs the high volts to be there to run.

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.

ABS light coming on,For this get the Engine computer scanned.It can be error codes stored in computer.------------

And now for clutch not going in gears it can be faulty clutch issue or problem with clutch cable.This has to be inspected.For more detailed instructions regarding Peugeot clutch problem,click the link below:-----

This will help.
Thanks.

Its the Auto Braking System.
This is the system that pulses your brake to reduce skidding when braking on gravel, ice, wet pavement...etc.
When this light comes on...more than likely it won't function correctly and your tires will lock up and skid.
Fixing the problem usually requires a brake job / brake replacement all the way around.


Hope this helps...

Try removing the negative cable from your battery for about sixty seconds, re install and see if the light continues to show on. It may have set a "soft" code and won't return. If it comes back on, you need to take it to a shop and have it diagnosed. Some states won't let you pass smog with that light on, like California.

If your ABS light is on, changing the brake (pads) won't fix the light.
There are several reasons for the ABS light to go on, and probably the most common is the connection to one of the four wheel speed sensors, or bad sensors. On most GMs, the sensor and wheel bearing are one assembly.
First, you need to get the error code read via the OBD2 plug. The dealer can do it of course. And many parts stores, such as AutoZone will scan for codes for free.
The code will give you a clue to the problem. Until the problem is fixed, the light can be reset, but it will turn back on almost right away.
