Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information BCM-0146

Condition





Note! This diagnostic trouble code (DTC) applies only to vehicles with dynamic stability and traction control (DSTC).

A factory test is performed to ensure that the various sub-systems within the brake system are functioning. The factory test consists of 4 parts:
1. The vehicle is driven at a speed above 20 km/h for 1 second
2. The vehicle decelerates below - 2.0 m/s2 (braking) for at least 1 second
3. The vehicle accelerates sideways above 1.5 m/s2 (vehicle speed [m/s] * yaw angle [rad/s]) and above 1.5 m/s2 for at least 1 second
4. The vehicle decelerates sideways below -1.5 m/s2 (vehicle speed [m/s] * yaw angle [rad/s]) and above -1.5 m/s2 for at least 1 second.
The sub-tests described above can be carried out in any order.
If the ignition is switched off before the test has been completed, all the conditions must be satisfied again the next time the ignition is switched on.
The diagnostic trouble code (DTC) is stored if the brake control module (BCM) registers that the factory tests for DSTC was failed.

Substitute value
- None.

Possible source
- Active yaw control operation during the factory test.

Note! This diagnostic trouble code (DTC) is not due to an internal hardware fault in the Brake control module (BCM) and must not be remedied by replacing the control module.

Fault symptom[s]
- Messages in the display.
