Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. 2. It is imperative that the vehicle be driven to attempt to reset the DTC. Using the scan tool to perform a function test may not produce the same result, and therefore may cause misdiagnosis of the vehicle.
  2. 7. This step tests if the EBCM is capable of activating the ABS pump motor.
  3. 8. A shorted ABS pump motor may damage the EBCM. It is imperative that the steps in the table be followed in order to prevent damage to a replacement EBCM.
