Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related fault codes that might provide additional information about the issue. | OBD-II Scanner |
| Test Drive Motor B Phase W Current Sensor | Use a multimeter or diagnostic tool to test the phase W current sensor in drive motor “B” and compare readings to manufacturer specifications. | Diagnostic Tool, Multimeter |
| Inspect Wiring for Damage | Visually inspect the wiring connected to the phase W current sensor for signs of damage, wear, or disconnections. Repair or replace as necessary. | Flashlight, Multimeter |
| Test Drive Motor B Operation | Perform a functional test on drive motor “B” to ensure it is operating correctly and there are no motor-related issues. | Diagnostic Tool |
| Check Ground Connections | Ensure that the current sensor and motor have proper grounding, as poor grounding can affect sensor readings. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After completing repairs, clear the fault code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0A6C code does not return. | OBD-II Scanner |
