Pinpoint Test G: The Traction Control System Is Inoperative Or 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.

G1 RETRIEVE AND RECORD DTCs
- Connect the scan tool.
- Ignition ON.
- Retrieve and record DTCs from the IC and the ABS module.
- Are any DTCs present?
- Yes : If DTCs were retrieved from the ABS module, GO to the ABS MODULE DTC CHART .
  If C1093 was retrieved from the IC, GO to G2. For all other IC DTCs , REFER to the DTC Chart in MULTIFUNCTION ELECTRONIC MODULE article.
- No : GO to G2.
G2 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 G3.
G3 ISOLATE THE STABILITY/TRACTION CONTROL SWITCH
- Ignition OFF.
- Disconnect: Stability/Traction Control Switch C2114.
- Measure the resistance between stability/traction control switch pin-7 and pin-1, component side, while pressing and releasing the switch.
- Is the resistance less than 5 ohms with the switch pressed and greater than 10, 000 ohms with the switch released?
- Yes : GO to G4.
- No : INSTALL a new stability/traction control switch. REFER to STABILITY/TRACTION CONTROL SWITCH in this service information. CLEAR the DTC. REPEAT the self-test.
G4 CHECK THE CONTROL CIRCUIT FOR A SHORT TO GROUND
- Disconnect: IC C220.
- Measure the resistance between stability/traction control switch C2355-7, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10, 000 ohms?
- Yes : GO to G5.
- No : REPAIR circuit CCA15 (YE/GY). CLEAR the DTC. REPEAT the self-test.
G5 CHECK THE CONTROL CIRCUIT FOR AN OPEN
- Measure the resistance between stability/traction control switch C2355-7, circuit CCA15 (YE/GY), harness side and IC C220-22, circuit CCA15 (YE/GY), harness side.

- Is the resistance less than 5 ohms?
- Yes : GO to G6.
- No : REPAIR circuit CCA15 (YE/GY). CLEAR the DTC. REPEAT the self-test.
G6 CHECK THE GROUND CIRCUIT FOR AN OPEN
- Measure the resistance between stability/traction control switch C2355-1, circuit GD114 (BK/BU), harness side and ground.

- Is the resistance less than 5 ohms?
- Yes : GO to G7.
- No : REPAIR circuit GD114 (BK/BU). CLEAR the DTC. REPEAT the self-test.
G7 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 INFORMATION CENTER - INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES article. 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.
