diagnostic car tool indicated by the fault code

Ways to Troubleshoot a Grand Prix ABS Light and Traction Manage Light 1Check the tires for proper wheel size and examine the fluid level in master cylinder diagnostic car tool. Improper tire size Auto code scanner, for instance two different sizes, will cause the wheels to turn at distinct speeds and may well set a false code when the laptop senses this as potential wheel lock-up. Low fluid level within the brake master cylinder will result in shutdown of your ABS and Traction Handle technique to prevent introduction of air into the brake technique.2Turn the ignition key off and insert the scan tool's connector in to the vehicle's diagnostic connector. The diagnostic connector in OBD-II equipped Grand Prix is situated below the driver's side of your dash close to the steering column. Turn the ignition crucial on and retrieve trouble codes in line with the instructions supplied with all the scan tool. In most instances you'll select "Read Codes" from the onscreen menu or push the "Read" button on the front in the scan tool to retrieve codes. Go to step two if the code indicates a wheel speed sensor fault or step five if the codes indicates a solenoid fault.3Select "Data" from the onscreen menu and scroll by way of the list until wheel speed sensor data is displayed on the screen. Test drive the auto even though monitoring the wheel speed signals, indicated from the fault code, on the scan tool. If the wheel speed signal is distinctive from the remaining wheel speed signals, test the resistance on the sensor.4Unplug the faulty wheel speed sensor, located on the back in the wheel bearing and hub assembly at each wheel in the Grand Prix and test the resistance in the sensor using your digital volt/ohm meter set to study resistance. The resistance of a very good wheel speed sensor will be1k ohms +/- 10 percent. Replace the sensor in the event the meter shows 0 ohms, infinite ohms, or the resistance is not 1k ohms +/- 10 percent.5Check fuses in the fuse block below the dash and below the hood. The fuses for the ABS and Traction Handle systems are marked on the physique of your fuse blocks. Replace any faulty fuses prior to continuing with the tests. Unplug the modulator valve assembly located on the driver's side from the passenger compartment near the master cylinder and test the resistance of solenoids utilizing you digital volt/ohm meter. Replace the modulator valve assembly if 0 ohms or infinite resistance are measured in the assembly.
