current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.
• NOTE: Check and rectify basic faults first 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 pinpoint tests, a fault is not present, an intermittent concern may be the cause. Always
check for loose connectors and corroded terminals.
