2. Disconnect the negative battery cable.
3. Remove the clutch switch.
4. Inspect continuity between the clutch switch terminals using an ohmmeter.
-
If not as specified, replace the clutch switch.

If clutch switch is okay, but PID value is out of specification, perform the "Circuit Open/Short Inspection".
5. Reconnect the clutch switch connector.
Circuit Open/Short Inspection
