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?
1. Yes: EXPLAIN correct system operation to the customer.
2. 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 CMDTCs .
- Are any DTCs present in the PCM, IC or ABS module?
1. 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 .
2. No: GO to G3 .
G3 VERIFY THE ABS MODULE CONFIGURATION
- 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?
1. Yes: The concern was due to improper or incomplete ABS module configuration.
2. No: GO to G4 .
G4 CHECK THE SIGNAL CIRCUIT FOR A SHORT TO GROUND
- For vehicles with navigation:
- Disconnect: FCIM C2403.
- For all other vehicles:
- Disconnect: HVAC-Dual Automatic Temperature Control (DATC) C228C (vehicles without navigation).
- Disconnect: IC C220.
- Measure the resistance between IC C220-18, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10,000 ohms?
1. Yes: For vehicles equipped with navigation, GO to G5 .
  For vehicles without navigation, GO to G6.
2. No: REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs. REPEAT the self-test.
G5 CHECK FOR CORRECT FCIM OPERATION
- Disconnect: FCIM C2403.
- Check for:
  - corrosion.
  - pushed-out pins.
  - spread terminals.
- Connect the FCIM connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
1. Yes: INSTALL a new FCIM . REFER to INFORMATION AND ENTERTAINMENT SYSTEMS . CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
2. 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. TEST the system for normal operation.
G6 CHECK FOR CORRECT HVAC-DATC OPERATION
- Disconnect: HVAC- DATC C228C.
- Check for:
  - corrosion.
  - pushed-out pins.
  - spread terminals.
- Connect the HVAC- DATC connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
1. Yes: INSTALL a new HVAC module. REFER to CLIMATE CONTROL . CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
2. 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. TEST the system for normal operation.
