Details of the c0899 OBD Code
Code C0899 indicates a fault in the Electronic Brake Control Module (EBCM) motor circuit.
OBD code C0899 means Yaw Rate Sensor Circuit Range/Performance.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects an issue with the yaw rate sensor circuit.
The yaw rate sensor is part of the vehicle’s stability control system and measures the rate of rotation around the vehicle’s vertical axis.
When the sensor circuit’s performance is out of the specified range, the EBCM sets this diagnostic trouble code (DTC) C0899.
Mechanic’s Tech Notes
Code C0899 indicates a fault in the Electronic Brake Control Module (EBCM) motor relay circuit.
OBDII code C0899 indicates a problem with the Transmission Control Module (TCM) power circuit.
To diagnose, use a voltmeter to check TCM power and ground connections for proper voltage levels.
Utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
Visually inspect wiring harnesses and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
If all connections appear intact, consider reprogramming or reflashing the TCM as a potential fix.
