Circuit/System Description

The electronic brake control module (EBCM) detects an internal malfunction.

Conditions for Running the DTC

* Ignition ON.

* Ignition voltage is greater than 10 volts.

Conditions for Setting the DTC

The EBCM detects an internal malfunction.

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS), traction control and the vehicle stability enhancement system for the duration of the

ignition cycle.

* A driver information center message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.

* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the EBCM.

2. Test for less than 1 ohm between the ground circuits listed below and ground.

* Terminal 13

* Terminal 38

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates between the B+ circuits listed below and ground.

* Terminal 1

* Terminal 25

瀚慖f the test lamp does not illuminate, test the appropriate circuit for a short to ground or an open/high resistance.

4. If all circuits test normal, replace the EBCM.
