Pinpoint Test G: The Stability/Traction Control System Is Inoperative

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

G1 VERIFY THAT THE SYSTEM CAN BE ENABLED/DISABLED BY THE STABILITY/TRACTION CONTROL SWITCH
- Test drive the vehicle, press the stability/traction control switch and verify that the system can be enabled/disabled by the switch.
- Can the system be enabled/disabled by the switch?
- Yes: EXPLAIN correct system operation to the customer.
- No: GO to G2 .
G2 CHECK FOR ABS MODULE, PCM AND IC DTCs
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - All Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Are any DTCs present in the PCM, IC or ABS module?
- Yes: For PCM DTCs, REFER to the INTRODUCTION - GASOLINE MODELS .
  For IC DTCs, REFER to the DTC CHART in MULTIFUNCTION ELECTRONIC MODULES .
  
  For ABS module DTCs, GO to the ABS MODULE DTC CHART .
- No: GO to G3 .
G3 VERIFY THAT THE ABS MODULE IS CONFIGURED FOR STABILITY/TRACTION CONTROL
- Configure the ABS module, refer to Programmable Module Installation (PMI) in MODULE CONFIGURATION .
- Test drive the vehicle and verify that the traction control system operates correctly.
- Does the system operate correctly?
- Yes: The concern was due to improper or incomplete ABS module configuration.
- No: GO to G4 .
G4 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO GROUND
- Disconnect: FCIM C2404B (vehicles with Navigation).
- Disconnect: HVAC-Dual Automatic Temperature Control (DATC) C288C (vehicles without Navigation).
- Disconnect: IC C220.
- Measure the resistance between IC C220-22, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10,000 ohms?
- 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: REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs. REPEAT the self-test.
