About C1497

C1497 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1497 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1497 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The C1497 fault code indicates the traction control or chassis control module has detected a short to battery voltage on the traction control motor potentiometer signal circuit. The potentiometer reports motor or secondary throttle position to the module via a 0V to 5V analog signal proportional to position. This code is specifically set when the module detects the signal pinned at battery voltage or above the 5V reference, indicating the signal wire is shorted directly to a battery feed somewhere in the wiring or inside the sensor. When this code is active, the module sees the motor position ...
