Pinpoint Test D: The Cruise Control Does Not Disengage When The Clutch Pedal Is Pressed

Refer to Wiring Diagram Set 31, Cruise Control for schematic and connector information Electrical Diagrams.

Normal Operation

Vehicles equipped with a manual transaxle have an additional clutch pedal cruise control deactivator switch. The clutch pedal cruise control deactivator (top travel) switch is a normally open switch with the clutch pedal released. When the clutch pedal is pressed, the clutch pedal cruise control deactivator switch moves to the closed position, which routes the ground signal to the Instrument Panel Cluster (IPC). The IPC (Instrument Panel Cluster) sends a network message over the High Speed Controller Area Network (HS-CAN) to the PCM, deactivating the cruise control system.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Clutch pedal cruise control deactivator switch

- IPC (Instrument Panel Cluster)

- PCM

PINPOINT TEST D : THE CRUISE CONTROL DOES NOT DISENGAGE WHEN THE CLUTCH PEDAL IS PRESSED

D1 CHECK THE CLUTCH PEDAL CRUISE CONTROL DEACTIVATOR SWITCH PID

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: PCM DataLogger.

- Monitor the PCM PID CPP_TOP while pressing and releasing the clutch pedal.

Does the PID value read "YES" with the clutch pedal pressed and "NO" with the clutch pedal released?

Yes
GO to D6.

No
GO to D2.

D2 CHECK THE CLUTCH PEDAL CRUISE CONTROL DEACTIVATOR SWITCH

- Ignition OFF.

- Disconnect: Clutch Pedal Cruise Control Deactivator Switch C277.

- Connect a fused jumper wire between the clutch pedal cruise control deactivator switch C277-2, circuit CE904 (GN/VT), harness side and the clutch pedal cruise control deactivator switch C277-3, circuit GD187 (BK/GN), harness side.





- Ignition ON.

- Enter the following diagnostic mode on the scan tool: PCM DataLogger.

- Monitor the PCM PID CPP_TOP.

Does the PID value read YES?

Yes
INSTALL a new clutch pedal cruise control deactivator switch. REFER to Cruise Control Deactivator Switch Cruise Control Deactivator Switch. TEST the system for normal operation.

No
GO to D3.

D3 CHECK THE CLUTCH PEDAL CRUISE CONTROL DEACTIVATOR SWITCH GROUND CIRCUIT FOR AN OPEN

- Ignition OFF.

- Connect a fused jumper wire between the clutch pedal cruise control deactivator switch C277-2, circuit CE904 (GN/VT), harness side and ground.





- Ignition ON.

- Enter the following diagnostic mode on the scan tool: PCM DataLogger.

- Monitor the PCM PID CPP_TOP.

Does the PID value read YES?

Yes
REPAIR circuit GD187 (BK/GN) for an open. TEST the system for normal operation.

No
GO to D4.

D4 CHECK THE CLUTCH PEDAL CRUISE CONTROL DEACTIVATOR SWITCH SIGNAL CIRCUIT FOR AN OPEN

- Disconnect: IPC (Instrument Panel Cluster) C220.

- Measure the resistance between the IPC (Instrument Panel Cluster) C220-10, circuit CE904 (GN/VT), harness side and the clutch pedal cruise control deactivator switch C277-2, circuit CE904 (GN/VT), harness side.





Is the resistance less than 5 ohms?

Yes
GO to D5.

No
REPAIR the circuit. TEST the system for normal operation.

D5 CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION

- Disconnect all the IPC (Instrument Panel Cluster) connectors.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all the IPC (Instrument Panel Cluster) connectors and make sure they are seated correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new IPC (Instrument Panel Cluster).

TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.

D6 CHECK FOR CORRECT PCM OPERATION

- Connect: All Disconnected Connectors.

- Disconnect all the PCM connectors.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all the PCM connectors and make sure they seat correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new PCM.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
