Details of the c1756 OBD Code
Code C1756 relates to an issue with the rear brake solenoid valve circuit.
OBD code C1756 indicates a steering angle sensor torque signal malfunction.
This code is triggered by the Electronic Stability Control (ESC) module when it detects an issue with the signal coming from the steering angle sensor related to torque.
The steering angle sensor is a critical component that helps the ESC system determine the driver’s intended direction and assists in stability control functions.
When this sensor malfunctions, it can affect the ESC system’s ability to operate effectively, potentially compromising vehicle stability and safety.
Mechanic’s Tech Notes
Code C1756 relates to a malfunction in the park brake motor switch circuit.
OBDII code C1756 relates to a transmission control module (TCM) power supply circuit malfunction.
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 checks out, consider reprogramming the TCM.
