CLUTCH SWITCH INSPECTION [ZM]

A3U014018660W02

Note

•

Perform the following test only when 
directed.

1. Verify that the clutch switch is installed properly.
2. Disconnect the negative battery cable.
3. Remove the clutch switch. (See 05–10–5 

CLUTCH PEDAL REMOVAL/INSTALLATION.)

4. Inspect continuity between the clutch switch 

terminals A and B using an ohmmeter.

•

If not as specified, replace the clutch switch.

•

If the clutch switch is okay, but PID value or 
PCM terminal 6 voltage is out of specification, 
carry out the “Circuit Open/Short Inspection”.
