What Does C1453 Mean?
This code indicates the traction control motor circuit is shorted to ground. The module has detected the motor circuit is being pulled to ground potential when it should not be, preventing proper bi-directional motor control. A ground short on a motor circuit can cause the motor to spin unexpectedly when the module energizes the opposite terminal, or it can cause the H-bridge driver to detect an overcurrent condition and shut down.
Common Causes
40%
Motor circuit wire insulation worn through where it contacts a chassis ground point, body panel, or engine mount bracket
25%
TC motor internal ground fault where the armature winding insulation has broken down and the winding shorts to the motor case/housing
20%
Water intrusion into the motor connector creating a ground path through moisture film between the signal pin and the connector body or ground pin
15%
ABS/TC module low-side H-bridge driver shorted internally, holding the output at ground
Diagnostic Steps
1
Step 1: Disconnect the TC motor connector and measure resistance from each motor pin to chassis ground. Both pins should read OL (open/infinite). A low resistance reading on either pin confirms a short to ground.
2
Step 2: If a short is found, disconnect the module end of the harness and recheck. If the short clears at the motor connector but is present at the module connector, the short is in the wiring harness between the two points.
3
Step 3: If the short is only present when the motor is connected, the motor has an internal ground fault. Bench-test the motor by measuring insulation resistance between each motor terminal and the motor housing using a megohmmeter if available (should be greater than 1M ohm).
4
Step 4: For harness shorts, systematically disconnect the harness at intermediate breakout points and measure to isolate the exact segment containing the short. Repair with proper sealed splices and re-route away from grounding surfaces.
5
Step 5: After repair, verify both motor circuit wires show infinite resistance to ground. Reconnect all connectors and use scan tool bidirectional control to verify proper motor operation in both directions.

The most common cause of C1453 (Traction Control Motor Circuit Short to Ground) is: Motor circuit wire insulation worn through where it contacts a chassis ground point, body panel, or engine mount bracket
Typical repair costs for C1453 range from $100 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A ground-shorted motor circuit disables traction control and could cause unintended motor movement if the module attempts to drive the motor. The vehicle will lack traction control intervention during wheel spin events.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1453 to identify the root cause.
