The electronic brake control module monitors how often the traction control or the stability control system activates in order to calculate an estimate of the front brake discs temperature. In most cases the high temperatures are caused by extended traction control activation. If the electronic brake control module calculates that the front brake components temperatures are too high, the electronic brake control module will temporarily suspend the traction control system function until the front brake discs cool down.

Ignition ON.

The electronic brake control module detects the calculated temperature of the brake components is higher than 500°C (932°F).

• The traction/stability control indicator turns ON.
• The electronic brake control module disables the ABS, the traction control, the stability control and the electronic brake distribution for the duration of the ignition cycle.

• The condition for setting the DTC is no longer present.
• The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

DTC C0179 does not indicate a malfunction has occurred. This DTC indicates there was excessive ABS, traction control or stability control activation that caused the high temperatures.

1. Allow the brakes to cool down before performing test.
2. Verify that no other DTCs are set.
• If any other DTCs are set

  Refer to Diagnostic Trouble Code (DTC) List - Vehicle.

• If no other DTCs are set
3. Verify DTC C0179 does not set while driving the vehicle under normal braking conditions.
• If the DTC sets

  Replace the K17 Electronic Brake Control Module.

• If the DTC does not set
4. All OK.

Perform the Diagnostic Repair Verification after completing the repair.
