Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional codes related to the motor, cooling system, or temperature sensors. | OBD-II Scanner |
| Test Drive Motor “B” for Overheating | Use a diagnostic tool to monitor the temperature of Drive Motor “B” and verify if the motor is overheating. | Diagnostic Tool |
| Inspect Temperature Sensor Operation | Test the Drive Motor “B” temperature sensor to ensure it is providing accurate readings and not triggering the over-temperature code falsely. | Multimeter, Diagnostic Tool |
| Check Cooling System for Issues | Inspect the cooling system components (coolant levels, fans, pumps, and hoses) for blockages, leaks, or malfunctions that could be causing the motor to overheat. | Flashlight, Multimeter |
| Replace Faulty Components | If necessary, replace the faulty temperature sensor, repair any damaged components of the cooling system, or address overheating issues in Drive Motor “B.” | Replacement Parts (Sensor, Cooling Components, Motor) |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and perform a test drive to ensure the motor operates within the correct temperature range. | OBD-II Scanner, Vehicle Manual |
| Recheck for Codes | Re-scan the system to ensure that the P0A35 code has been cleared successfully. | OBD-II Scanner |
