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?
1. 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 o the DTC Chart in MULTIFUNCTION ELECTRONIC MODULES .
2. 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?
1. Yes : INFORM the customer that the key being used is MyKey™ -restricted. If necessary, Refer o the Owner's Literature for information regarding the programming of MyKey™ features. Using an Administrator key, TEST the system for normal operation.
2. 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?
1. Yes : GO to G4 .
2. No : INSTALL a new stability/traction control switch. Refer o STABILITY/TRACTION CONTROL SWITCH . 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?
1. Yes : GO to G5 .
2. 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?
1. Yes : GO to G6 .
2. 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?
1. Yes : GO to G7 .
2. 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?
1. Yes : INSTALL a new IC . Refer o INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . CLEAR the DTCs. REPEAT the self-test.
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.
