DIAGNOSTIC TROUBLE CODE INDEX: ANTI-LOCK BRAKE SYSTEM (ABS) - DTC: ANTI-LOCK BRAKE SYSTEM CONTROL MODULE (ABS) (G1566096)

DESCRIPTION AND OPERATION
 
 
ANTI-LOCK BRAKE SYSTEM CONTROL MODULE (ABS)
CAUTION:

Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTES:
  • If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new module/component.

  • Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).

  • When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into account.

  • Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

  • Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.

  • If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.

  • Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Anti-lock Brake System Control Module (ABS). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop manual.
