Pinpoint Test N: The Stability/Traction Control System 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.

N1 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 Manual for information regarding the programming of MyKey™ features. Using an administrator key, TEST the system for normal operation.
- No: GO to N2.
N2 ISOLATE THE STABILITY/TRACTION CONTROL SWITCH
- Disconnect: FCIM C2403.
- Ignition ON.
- Connect a fused jumper wire to FCIM C2403-7, circuit CCA15 (YE/GY), harness side and momentarily connect the other end of the jumper wire to ground.

- As the jumper wire is connected to ground, observe the sliding-car OFF icon in the message center.
- Does the sliding-car OFF icon illuminate when the jumper wire is connected to ground?
- Yes: INSTALL a new FCIM . REFER to INFORMATION AND ENTERTAINMENT SYSTEMS . CLEAR the DTCs. REPEAT the self-test.
- No: GO to N3.
N3 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: IC C220.
- Measure the resistance between IC C220-18, circuit CCA15 (YE/GY), harness side and FCIM C2403-7, circuit CCA15 (YE/GY), harness side.

- Is the resistance less than 5 ohms?
- Yes: GO to N4.
- No: REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
N4 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO GROUND
- Measure the resistance between IC C220-18, circuit CCA15 (YE/GY), harness side and ground.

- Is the resistance greater than 10,000 ohms?
- Yes: GO to N5.
- No: REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs.
N5 CHECK THE STABILITY/TRACTION CONTROL SWITCH CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition ON.
- Measure the voltage between IC C220-18, circuit CCA15 (YE/GY), harness side and ground.

- Is any voltage present?
- Yes: REPAIR circuit CCA15 (YE/GY). CLEAR the DTCs.
  REPEAT the self-test.
- No: GO to N6.
N6 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, MESSAGE CENTER, AND 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.
