About C1962

C1962 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 C1962 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.

C1962 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 park lamp relay coil is controlled by the body or lighting control module to switch power to the parking lamps. DTC C1962 sets when the module detects that the park lamp relay coil control circuit is shorted to battery voltage, meaning the coil circuit sees voltage when it should not. This can hold the relay energised or present an unexpected high level on the control circuit that the module reads as a fault. When this code is set the parking lamps may stay on or operate incorrectly, and the module flags the coil circuit short to battery.
