Pinpoint Test K: The Traction Control System Cannot Be Disabled: Testing

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

K1 MONITOR THE INSTRUMENT CLUSTER PID
- Connect the diagnostic tool.
- Key in ON position.
- Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Traction Control Status PID.
- Monitor the instrument cluster traction control switch status PID and the traction control disable indicator while pressing the traction control disable switch repeatedly.
- Does the PID agree with the switch position, and does the traction control disable indicator match?
- Yes : The system is operating correctly at this time.
- No : GO to K2.
K2 CHECK CIRCUIT 1412 (WH/PK) FOR A SHORT TO GROUND
- Key in OFF position.
- Disconnect: Traction Control Switch C2114.
- Disconnect: Instrument Cluster C220.
- Measure the resistance between the traction control switch C2114-2, circuit 1412 (WH/PK), harness side and ground.

- Is the resistance greater than 10,000 ohms?
- Yes : GO to K3.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
K3 CHECK THE TRACTION CONTROL SWITCH INPUT
- Connect: Traction Control Switch C2114.
- Make sure the traction control switch is not pressed (traction control not disabled).
- Measure the resistance between the instrument cluster C220-9, circuit 1412 (WH/PK), harness side and ground.

- Is the resistance greater than 10,000 ohms?
- Yes : GO to K4.
- No : INSTALL a new traction control switch. CLEAR the DTCs. REPEAT the self-test.
K4 CHECK THE TRACTION CONTROL SWITCH OPERATION
- Key in OFF position.
- Disconnect: Instrument Cluster C220.
- Measure the resistance between the instrument cluster C220-9, circuit 1412 (WH/PK), harness side and ground while pressing the traction control switch.

- Is the resistance less than 5 ohms?
- Yes : GO to K7.
- No : GO to K5.
K5 CHECK CIRCUIT 1412 (WH/PK) FOR AN OPEN
- Disconnect: Traction Control Switch C2114.
- Measure the resistance between the instrument cluster C220-9, circuit 1412 (WH/PK), harness side and the traction control switch C2114-2, circuit 1412 (WH/PK), harness side.

- Is the resistance less than 5 ohms?
- Yes : GO to K6.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
K6 CHECK CIRCUIT 1205 (BK) FOR AN OPEN
- Measure the resistance between the traction control switch C2114-4, circuit 1205 (BK), harness side and ground.

- Is the resistance less than 5 ohms?
- Yes : INSTALL a new traction control switch. CLEAR the DTCs. REPEAT the self-test.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
K7 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect the instrument cluster connector.
- Check for:
  - corrosion
  - pushed-out pins
- Connect the instrument cluster connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . CLEAR the DTCs. REPEAT the self-test.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
