Scheme 107: Diagnostic trouble code (DTC) information
Scheme 107: Diagnostic trouble code (DTC) information

In cars with traction control (STC/DSTC/TRACS), the brake control module registers how much the brakes are used and then calculates the temperature of all brake discs. Diagnostic trouble code (DTC) BCM-0061 is stored if the calculated temperature exceeds 450°C.

The diagnostic trouble code (DTC) can be diagnosed while the ignition is switched on.

Substitute Value

  1. Traction control is blocked.

HINT: For information about brake system abbreviations, see Brake system, abbreviations .

Possible Source

  1. Excessive anti-spin control
  2. Brakes applied too long (brakes have been used so much that brake disc temperature has become too high).

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]

  1. Anti-spin does not function. NOTE: The anti-spin function is deactivated until the temperature of the brake discs is below 300°C.

Visual inspection of brakes

  1. Remove the front wheels. Check the brakes for the front wheel visually. Check there is no overheating damage to brake caliper, brake pads or brake disc. Replace damaged components. Tell the customer why the anti-spin function was temporarily blocked and why the ABS warning lamp was lit. Remedy as necessary. Other information To remove or replace brake calipers, see «Brake calipers front, replacing»(ref-406847-S25117676152011070100000) To remove or replace brake pads, see «Brake pads front, replacing»(ref-406847-S36468335502011070100000) To remove or replace brake discs, see «Brake disc front, replacing»(ref-406847-S02881809532011070100000) .
