About C1496

C1496 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 C1496 is stored, the module has detected an open (broken or disconnected) electrical path 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.

C1496 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 C1496 fault code indicates the traction control or chassis control module has detected an open circuit on the traction control motor potentiometer signal. The potentiometer reports motor or secondary throttle position feedback to the module via a 0V to 5V analog signal. This code is specifically set when the module sees no signal at all on the position wire, indicating either an open winding inside the potentiometer track, an open circuit in the signal wire, a missing 5V reference voltage, or an open ground at the sensor. When this code is active, the module loses motor position feedback, ...
