When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and with a current 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 that involve 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.
