Multifunction Electronic Modules: Diagnosis Jaguar XKR II рестайлинг

INSPECTION AND VERIFICATION

1. Verify the customer concern.
2. Visually inspect for obvious signs of electrical damage. Visual Inspection Electrical Fuse(s) Electrical connector(s) Wiring Harness
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident, check for DTCs and refer to the DTC Index.

DTC INDEX

Note. If the control module is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval program is in operation, prior to the installation of a new module.

Note. The DTC Index in this section shows information for DTCs that could be logged in the Driver Door Module (DDM) or Passenger Door Module (PDM). For diagnosis and testing information for: Driver/Passenger Seat module. Refer to DTC: DRIVER/PASSENGER DOOR MODULE (DDM/PDM) information.

Note. Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information read by the manufacturer approved diagnostic system).

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

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

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

Note. 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.
