NEUTRAL SWITCH INSPECTION

Inspection of Continuity

NOTE: Perform the following test only when directed.

1. Disconnect the negative battery cable.
2. Remove the neutral switch.







3. Inspect for continuity between the neutral switch terminals using an ohmmeter.
- If not as specified, replace the neutral switch.
- If neutral switch is okay but PID value is out of specification, perform the "Circuit Open/Short Inspection".

4. Reconnect the neutral switch connector.

Circuit Open/Short Inspection

- GND circuit (Neutral switch connector terminal B and GND through common connector.)
