Clutch Switch: Testing and Inspection

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.




4. Inspect the 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 are out of specification, carry out the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection
1. Remove the PCM.

Specification:

2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.

Tightening torque:
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}




4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST (104 Pin Breakout Box) terminals with ohmmeter leads.
- If there is an open or short circuit, repair or replace wiring harnesses.
- If there is no open or short circuit, replace the clutch switch.

Open circuit
- Power circuit (Clutch switch connector terminal B and PCM connector terminal 6 through common connector)
- GND circuit (Clutch switch connector terminal A and GND)

Short circuit
- Power circuit (Clutch switch connector terminal B and PCM connector terminal 6 through common connector to GND)

5. Install the clutch switch.
