INSPECTION AND VERIFICATION
| 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. |
- Verify the customer concern.
- Visually inspect for obvious signs of damage and system integrity. NOTE: Particular attention should be paid to the following items where DTCs may not be logged: Check for contamination (e.g. dirt, grime, frosting, ice) around the blindspot monitoring sensors and clear. Visual Inspection Mechanical Electrical Exterior rear view mirror glass Mud or sleet contamination around rear bumper area Blindspot Monitoring Modules Fuse(s) Relay(s) Wiring Harness Electrical connector(s) Blindspot Monitoring Modules
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC INDEX
| CAUTION | When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00. |
Note. If the control module or a component 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 programme is in operation, prior to the installation of a new module/component.
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 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.
Note. When carrying out repair/diagnosis of the system, on removal of the front or rear bumper inspect the sensor connectors to ensure they were correctly latched and check fly leads for signs of chaffing or trapped wires.
Note. 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
