Pontiac Grand Prix ABS, No Codes- All Pads and Rotors Replaced

• Comments ⇓

1995 Pontiac Grand Prix. Replaced pads rotors and recent master cylinder. Question: this is an intermittent trouble after driving for a while the abs light comes on there are no codes stored in the computer. This has been an ongoing trouble that began long before this last brakeservice. I have connected the AutoXray 5000 scanner to the computer port and had the car driven when the abs light comes on no fault codes are displayed.

We have replaced the master cylinder and completely bled the entire brake system starting at the distribution abs modulator block all the way to the calipers. The brakes work fine but the abs light still comes on after driving the amount of driving varies we are leaning heavily to an electrical and or electronic failure of the ABS control module but would like some assistance to narrow the trouble down.

ANSWER:

I am not familiar with this model scanner, but i assume it is capable of reading codes. Does this scanner only read engine codes? If so, you will not see ABS codes. An ABS lighton with not codes is usually an EBCM (Electronic Brake Control Module) problem. But, you need to be sure the scanner is able to read them, or this will give you false information and lead you down the wrong path to diagnosis and repairs.

Anytime there is a warning light, there SHOULD be codes. I have not had many ABS lights without codes. Motor packs are common, speed sensors, harnesses, but ALWAYS codes. I would suggest checking with a different scanner to be sure.

Question:
I was wondering if the brake booster off a 2006 Pontiac grand Prix will work on a 1999 GMC Jimmy. Very urgent I have absolutely no brakes.

Answer:
The simple answer is no. Vacuum Requirements: Brake boosters typically rely on engine vacuum to assist with braking. The vacuum requirements of the Pontiac Grand Prix's brake booster may not match those of the GMC Jimmy's engine.

Braking Performance: Even if the brake booster physically fits and functions, there's no guarantee that it will provide the same braking performance as the original component. Differences in design, hydraulic pressure, and vacuum assistance could affect braking feel and effectiveness.

Given these considerations, it's generally recommended to use brake components specifically designed for your vehicle's make and model. Installing parts from a different vehicle, especially critical safety components like the brake booster, can introduce unnecessary risks and potential complications.
