Possible Causes

  1. AL1: Check For Other ABS Module DTCs 
    • Clear the ABS DTCs.
    • Put the ABS module in sleep mode by performing the following steps:
      • With ALL doors closed, set the ignition from ON to OFF.
      • Disconnect the diagnostic scan tool.
      • Open the door, exit the vehicle and close the door.
      • Wait a minimum of 90 seconds for the ABS module to enter sleep mode.
    • Ignition ON, engine OFF.

      Carry out the ABS self-test.

    • Are any wheel speed sensor DTCs present which are NOT shown in the DTC Fault Trigger Conditions table? 
    Yes No
    DIAGNOSE those DTCs first. REFER to the ABS Module DTC Chart. INSTALL a new wheel speed sensor for the one in question. REFER to the appropriate Removal and Installation procedure in the Anti-Lock Brake System (ABS) and Stability Control article.
