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

NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

L1 ISOLATE THE STABILITY/TRACTION CONTROL SWITCH
- Disconnect: FCIM C2404B (vehicles with Navigation).
- Disconnect: HVAC-Dual Automatic Temperature Control (DATC) C288C (vehicles without Navigation).
- Ignition ON.
- For vehicles with Navigation, connect a fused jumper wire to FCIM C2402B-7, circuit CCA15 (YE/GY), harness side and momentarily connect the other end of the jumper wire to ground.
- For vehicles without Navigation, connect a fused jumper wire to HVAC- DATC C288C-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 stability/traction control indicator in the IC or message center (if equipped).
- Does the stability/traction control indicator 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 L2 .
L2 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: IC C220 (all vehicles).
- For vehicles with Navigation, measure the resistance between IC C220-22, circuit CCA15 (YE/GY), harness side and FCIM C2402B-7, circuit CCA15 (YE/GY), harness side.
- For vehicles without Navigation, measure the resistance between IC C220-22, circuit CCA15 (YE/GY), harness side and FCIM C2402B-7, circuit CCA15 (YE/GY), harness side.

- Is the resistance less than 5 ohms?
- Yes: GO to L3 .
- No: REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
L3 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO GROUND
- Measure the resistance between IC C220-22, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10,000 ohms?
- Yes: GO to L4 .
- No: REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs. REPEAT the self-test.
L4 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition ON.
- Measure the voltage between IC C220-22, 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 L5 .
L5 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.
