  • C1662 can be caused by a faulty Parking Assist ECU.
  • A Parking Assist ECU harness that is open or shorted.
  • A Parking Assist ECU circuit with a poor electrical connection.

To address fault code C1662, inspect the wiring harness for any damage or loose connections.

  • To fix OBDII code C1662, first, review the possible causes related to this code.
  • Visually examine the wiring harness and connectors associated with the ABS module.
  • Check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
  • If no visible issues are found, perform a reset on the ABS module to clear any stored fault codes.
  • Test drive the vehicle to see if the code returns.
  • If the code persists, consider replacing the ABS module with a new one and program it to the vehicle as needed.

Diagnosing and repairing fault code C1662 may involve inspecting and testing the vehicle’s suspension system components.

The cost to diagnose and fix OBD code C1662 depends on the estimated 1. 0hour repair time.

Labor rates range from $75 to $150 per hour, so the general cost could be between $75 and $150. The final cost may vary based on shop rates and the complexity of the repair.

Code C1662 relates to an issue with the cruise control brake switch circuit.

OBD code C1662 means that there is a fault in the suspension system pressure sensor circuit.

This code is triggered by the suspension control module when it detects a problem with the pressure sensor circuit.

The suspension system pressure sensor is responsible for monitoring the pressure in the suspension system to ensure proper operation and performance.

When this sensor circuit malfunctions, it can lead to issues with the suspension system’s ability to adjust and maintain the correct pressure levels, affecting the vehicle’s ride quality and handling.

Code C1662 indicates a fault in the cruise control brake switch circuit.

OBDII code C1662 indicates a communication error between the transmission control module (TCM) and the engine control module (ECM).

To diagnose, check TCM power and ground using a multimeter.

Use a scan tool to confirm TCM response over the Controller Area Network (CAN) network.

Visually inspect wiring harnesses and connectors for damage, and check connector pins for issues like corrosion or bending.

Reflashing the TCM may be necessary to resolve the communication problem.
