Pinpoint Test Y: The Traction Control/Stability Assist Indicator Is Never/Always On

Normal Operation

The traction control/stability assist indicator informs the driver that a traction control or stability assist event is taking place by flashing the traction control/stability assist indicator during the event. The traction control/stability assist indicator illuminates constantly (not flashing) when a malfunction is detected in the traction control or stability assist system, or if the traction control or stability assist system is disabled by the operator. The ABS module sends a message to the Instrument Cluster (IC) along the High Speed Controller Area Network (HS-CAN) bus to illuminate the traction control/stability assist indicator.

This pinpoint test is intended to diagnose the following:

- Traction control/stability assist system concern
- ABS module
- IC



PINPOINT TEST Y: THE TRACTION CONTROL/STABILITY ASSIST INDICATOR IS NEVER/ALWAYS ON

-------------------------------------------------
Y1 CHECK THE TRACTION CONTROL/STABILITY ASSIST INDICATOR OPERATION USING THE STABILITY/TRACTION CONTROL DISABLE SWITCH


- Ignition ON.
- Press the traction control/stability assist disable switch once to disable the traction control/stability assist system then press the traction control/stability assist switch again while monitoring the traction control/stability assist indicator.
- Does the traction control/stability assist indicator illuminate with the first switch press and turn off with the second switch press?

Yes
If the traction control/stability assist indicator does not operate while in traction active mode, INSTALL a new ABS module. REFER to Antilock Brakes / Traction Control Systems. TEST the system for normal operation.

If the traction control/stability assist indicator operates in traction active mode, the system is operating normally at this time.

No
GO to Y2.

-------------------------------------------------
Y2 RETRIEVE THE RECORDED DTCs FROM THE ABS MODULE SELF-TEST


- Check for recorded ABS module DTCs from the self-test.
- Are any ABS module DTCs recorded?

Yes
REFER to Antilock Brakes / Traction Control Systems.

No
GO to Y3.

-------------------------------------------------
Y3 CARRY OUT THE IC INDICATOR LAMP CONTROL ACTIVE COMMAND USING THE SCAN TOOL


- Enter the following diagnostic mode on the scan tool: IC DataLogger.
- Select the IC traction control/stability assist active indicator (ACTIVELMP) active command. Command the traction control/stability assist indicator on and off. Observe the stability/traction control indicator.
- Does the traction control/stability assist indicator illuminate when commanded on, and turn off when commanded off?

Yes
REFER to Antilock Brakes / Traction Control Systems to diagnose the traction control/stability assist system cannot be disabled.

No
INSTALL a new IC. REFER to Instrument Cluster (IC) Instrument Cluster (IC). TEST the system for normal operation.
