Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
Diagnostic Test
| 1. | Ignition on, engine not running. |
| 2. | With the scan tool, clear DTCs in the PCM. |
| 3. | Press and release the clutch pedal several times. |
| 4. | With the scan tool, select View DTCs. |
Is the status Active for this DTC?
Yes
- Go To 2
No
- Perform the INTERMITTENT DTC diagnostic procedure. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
2. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT VOLTAGE
 |
| 1. | Turn the ignition off. |
| 2. | Disconnect the Clutch Interlock Switch harness connector. |
| 3. | Turn the ignition on. |
| 4. | Measure the voltage of the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector. |
Is the voltage above 10.0 volts?
Yes
- Go To 3
No
- Go To 5
3. CHECK THE (Z905) GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE
 |
| 1. | Using a 12-volt test light connected to 12 volts, check the (Z905) Ground circuit in the Clutch Interlock Switch harness connector. |
| NOTE: | The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery. |
Is the test light illuminated and bright?
Yes
- Go To 4
No
- Repair the (Z905) Ground for an open or high resistance.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
4. CHECK THE CLUTCH INTERLOCK SWITCH
 |
| 1. | Turn the ignition off. |
| 2. | Connect a jumper between the (Z905) Ground circuit and the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector. |
| 3. | Turn the ignition on. |
| 4. | With the scan tool, monitor the Clutch Interlock status. |
| NOTE: | The scan tool should display the Clutch Interlock status as pressed with the jumper in place and not pressed with the jumper removed. |
Does the scan tool display the status as described above?
Yes
- Replace the Clutch Interlock Switch in accordance with the service information.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
- Go To 9
5. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND
 |
| 1. | Turn the ignition off. |
| 2. | Disconnect the PCM C1 harness connector. |
| 3. | Measure the resistance between ground and the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector. |
Is the resistance above 10k Ohms?
Yes
- Go To 6
No
- Repair the (T141) Clutch Interlock Switch Signal circuit for a short to ground.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
6. CHECK THE (T26) CLUTCH UPSTOP SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND
| 1. | Turn the ignition off. |
| 2. | Disconnect the Clutch Switch harness connector. |
| 3. | Measure the resistance between ground and the (T26) Clutch Upstop Switch Signal circuit at the Clutch Switch harness connector. |
Is the resistance above 10k Ohms?
Yes
- Go To 7
No
- Repair the (T26) Clutch Upstop Switch Signal circuit for a short to ground.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
7. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
Do not probe the PCM harness connectors. Probing the PCM harness
connectors will damage the PCM terminals resulting in poor terminal
to pin connection. Install the GPEC Diagnostic Adaptor to perform
the diagnosis.
CAUTION:
| 1. | Connect the Adapter, GPEC Diagnostic 10436 . |
| 2. | Measure the resistance of the (T141) Clutch Interlock Switch Signal circuit between the Clutch Interlock Switch harness connector and the GPEC Adaptor. |
Is the resistance below 5.0 Ohms?
Yes
- Go To 8
No
- Repair the (T141) Clutch Interlock Switch Signal circuit for an open or high resistance.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
8. CHECK THE (T26) CLUTCH UPSTOP SWITCH SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
| 1. | Measure the resistance of the (T26) Clutch Upstop Switch Signal circuit between the Clutch Switch harness connector and the GPEC Adaptor. |
Is the resistance below 5.0 Ohms?
Yes
- Go To 9
No
- Repair the (T26) Clutch Upstop Switch Signal circuit for an open or high resistance.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
| 1. | Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Clutch Interlock Switch and the Powertrain Control Module (PCM). |
| 2. | Look for any chafed, pierced, pinched, or partially broken wires. |
| 3. | Look for broken, bent, pushed out or corroded terminals. |
| 4. | Perform any Technical Service Bulletins that may apply. |
Were any problems found?
Yes
- Repair as necessary.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
- Replace the Powertrain Control Module in accordance with the service information.
- Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
