Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code information BCM-C002201

Condition





Note! The diagnostic trouble code only applies to brake systems with DSTC.

During stability control, the brake control module (BCM) sends a signal to the pressure build-up valve, which opens and allows atmospheric pressure to enter the brake booster, which automatically increases brake pressure in the brake system. This function is used by the anti-skid function and active brake assist (BA).
Diagnostic trouble code BCM-C002201 is generated if the brake control module (BCM) registers an unreasonable signal from the pressure build-up valve.

Substitute value
