P0830-CLUTCH PEDAL SWITCH CIRCUIT

For a complete wiring diagram, refer to the Wiring Information.

When Monitored:
While driving the vehicle and shifting gears.
Set Condition:
The Powertrain Control Module (PCM) does not detect changes in the Clutch Interlock Switch Signal circuit voltage or the Clutch Upstop Signal circuit voltage while CAN messages from the Transmission Control Module indicate transmission gear changes.

(T26) CLUTCH UPSTOP SWITCH SIGNAL CIRCUIT SHORTED TO GROUND
(T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT OPEN/HIGH RESISTANCE
(T26) CLUTCH UPSTOP SWITCH SIGNAL CIRCUIT OPEN/HIGH RESISTANCE
(Z905) GROUND CIRCUIT OPEN/HIGH RESISTANCE
CLUTCH INTERLOCK SWITCH
POWERTRAIN CONTROL MODULE (PCM)

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

1. DTC IS ACTIVE

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

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

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

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 wire between the (Z904) 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 wire in place and not pressed with the jumper wire 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).

5. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND

1.	Turn the ignition off.

2.	Remove the jumper.

3.	Reinstall the ASD Relay.

4.	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 7

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

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

1.	Measure the resistance of the (T141) Clutch Interlock Switch Signal circuit between the Clutch Interlock Switch harness connector and the PCM C2 harness connector.

Is the resistance below 5.0 Ohms?

Yes

Go To 8

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 PCM C3 harness connector.

Is the resistance below 5.0 Ohms?

Yes

Go To 9

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).

9. POWERTRIAN CONTROL MODULE

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.
