Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that may provide more context for the torque delivery issue. | OBD-II Scanner |
| Test Torque Delivery Against Specifications | Use a diagnostic tool to measure the torque output of Drive Motor “B” and compare it to the manufacturer’s specifications. Any significant deviations from the expected torque range should be addressed. | Torque Diagnostic Tool, Vehicle Manual |
| Inspect Torque Sensor and Wiring | Inspect the torque sensor for any signs of damage or malfunction. Also, check the wiring and connectors for loose connections, corrosion, or damage that could interfere with sensor performance. | Multimeter, Flashlight, Safety Gloves |
| Test the Torque Sensor | Use a multimeter or diagnostic tool to verify the output from the torque sensor. Compare the readings to manufacturer specifications. Replace the sensor if it is not performing correctly. | Multimeter, Diagnostic Tool |
| Check for Drive Motor Issues | Inspect Drive Motor “B” for any internal mechanical wear, electrical issues, or faults that could affect torque delivery. | Diagnostic Tool, Vehicle Manual |
| Clear the Code and Test Drive | After completing the necessary repairs, clear the fault code using an OBD-II scanner and conduct a test drive to ensure proper torque delivery. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the system to ensure that the P0C1A code does not return. | OBD-II Scanner |
