Pinpoint Test N: The Stability/Traction Control System Cannot Be Disabled

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

N1 VERIFY THAT THE KEY IN USE IS NOT RESTRICTED
- Ignition ON.
- Monitor the message center while pressing the stability/traction control switch.
- Is ADVTRAC ON MY KEY SETTING displayed in the message center?
  - Yes : INFORM the customer that the key being used is MyKey™ -restricted. If necessary, REFER to the Owner's Literature for information regarding the programming of MyKey™ features. Using an administrator key, TEST the system for normal operation.
  - No : GO to N2.
N2 ISOLATE THE STABILITY/TRACTION CONTROL SWITCH
- Vehicles with navigation:
- Disconnect: FCIM C2403.
- Vehicles without navigation:
- Disconnect: HVAC-Dual Automatic Temperature Control (DATC) C228C.
- Ignition ON.
- Vehicles with navigation: Connect a fused jumper wire to FCIM C2403-7, circuit CCA15 (YE/GY), harness side and momentarily connect the other end of the jumper wire to ground.

- As the jumper wire is connected to ground, observe the sliding-car OFF icon in the message center.
- Does the sliding-car OFF icon illuminate when the jumper wire is connected to ground?
  - Yes : If the vehicle is equipped with navigation, INSTALL a new FCIM. REFER to INFORMATION AND ENTERTAINMENT SYSTEMS .
    If the vehicle is not equipped with navigation, INSTALL a new HVAC module. REFER to CLIMATE CONTROL .
    
    CLEAR the DTCs. REPEAT the self-test.
  - No : GO to N3.
N3 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: IC C220 (all vehicles).
- Vehicles with navigation: Measure the resistance between IC C220-18, circuit CCA15 (YE/GY), harness side and FCIM C2403-7, circuit CCA15 (YE/GY), harness side.

- Is the resistance less than 5 ohms?
  - Yes : GO to N4.
  - No : REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
N4 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO GROUND
- Measure the resistance between IC C220-18, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10, 000 ohms?
  - Yes : GO to N5.
  - No : REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs. REPEAT the self-test.
N5 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition ON.
- Measure the voltage between IC C220-18, circuit CCA15 (YE/GY), harness side and ground.

- Is any voltage present?
  - Yes : REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs. REPEAT the self-test.
  - No : GO to N6.
N6 CHECK FOR CORRECT IC OPERATION
- Check IC C220 for:
  - corrosion.
  - pushed-out pins.
  - spread terminals.
- Connect the IC 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 IC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . 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.
