The electronic brake control module (EBCM) monitors Traction Control System (TCS) activation in order to calculate an estimate of the EBCM solenoid valve temperatures. In most cases high solenoid valve temperatures are caused by extended TCS activation. If the EBCM calculates that the solenoid valve temperatures are too high, the EBCM will temporarily suspend the TCS function until the solenoid valves cool.
• | Ignition ON. |
• | Ignition voltage is greater than 8 volts. |
The estimated solenoid coil temperature reaches 220°C (428°F).
• | The EBCM disables the TCS for the duration of the ignition cycle. |
• | The driver information center (DIC) displays the SERVICE TRACTION CONTROL message. |
• | The DIC displays the Vehicle Stability Enhancement System (VSES) inhibited. |
• | After the solenoid valves have cooled the EBCM automatically re-enables TCS function. |
• | The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |
Most occurrences of this DTC are caused by excessive TCS activation or braking.

Important: Allow brakes to cool down before performing test.
⇒ | If the DTC resets replace the EBCM. |
