Gateway Module (GWM)

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
NOTE:
  • Guided Diagnostics must be followed and the repair advised by the process completed. Failure to do so may result in the rejection of any warranty claim made.
  • If the control module or a component is at fault or may be at fault and the vehicle remains under manufacturer warranty, refer to the warranty policy and procedures information, or determine if any prior approval program 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 Jaguar Land Rover approved diagnostic equipment)
  • When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a current 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 Diagnostic Trouble Code(s) 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
  • Where an 'on demand self-test' is referred to, this can be accessed through the 'diagnostic trouble code monitor' tab on the manufacturers approved diagnostic system
  • Check JLR claims submission system for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific customer complaint and complete the recommendations as required.

The article below lists all Diagnostic Trouble Code(s) that could be set in the gateway module, for additional diagnosis and testing information refer to the relevant diagnosis and testing article. For additional information, Refer to: BATTERY
