Pinpoint tests CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00. Failure to follow this instruction may result in damage to the vehicle.
NOTE:
When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 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:
If DTCs are recorded and a fault is not present when performing the pinpoint tests, an intermittent concern may be the cause. Always check for loose connections and corroded terminals.
