Pinpoint Test G: The Traction Control System Is Inoperative Or Cannot Be Disabled

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

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 .
- 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 My Key™ - restricted. If necessary, refer to the Owner's Literature for information regarding the programming of My Key TM 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 information. CLEAR the DTC. REPEAT the self-test.
G4 CHECK CIRCUIT CCA15 (YE/GY) FOR A SHORT TO GROUND
- Disconnect: IC C220.
- Measure the resistance between stability/traction control switch C2114-7, 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 CIRCUIT CCA15 (YE/GY) FOR AN OPEN
- Measure the resistance between stability/traction control switch C2114-7, 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 CIRCUIT GD114 (BK/BU) FOR AN OPEN
- Measure the resistance between stability/traction control switch C2114-1, 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 INSTRUMENTATION SYSTEM, MESSAGE CENTER & 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.
