Diagnosis Procedure
WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK POWER SWITCH (PUSH SWITCH) OUTPUT SIGNAL
- Disconnect power switch connector and IPDM E/R connector.
- Check voltage between power switch harness connector and ground.TERMINALS VOLTAGE REFERENCE CHART
(+) (-) Voltage (V) (Approx.) Power switch Connector Terminal M25 8 Ground 12 Is the inspection result normal?
YES: GO TO 3.
NO: GO TO 2.
- CHECK POWER SWITCH CIRCUIT (BCM)
- Disconnect BCM connector.
- Check continuity between BCM harness connector and power switch harness connector.TERMINALS CONTINUITY REFERENCE CHART
