Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code information BCM-U040164

Condition





Note! The diagnostic trouble code only applies to vehicles equipped with STC/DSTC.

The engine control module (ECM) sends a signal to the brake control module (BCM) via CAN to indicate whether the rpm signal is correct. The brake control module (BCM) uses the rpm signal to control the stability function.
Diagnostic trouble code BCM-U040164 is generated if the brake control module (BCM) registers that the engine control module (ECM) has sent a signal indicating that the rpm signal is unreasonable.
The diagnostic trouble code can be diagnosed after the engine has started.

Substitute value
- TC is blocked.
- SC is blocked.
- AYC is blocked.

Hint: For information on abbreviations: Brake system, abbreviations, B6324S5 Testing and Inspection

Possible source

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]
- General warning light on.
