DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition SOBDMC P0C51:00 Drive Motor "A" Position Sensor Circuit "A" Range/Performance: No Sub Type Information This DTC sets when a wiring concern in the harness between the Inverter System Controller (ISC) and the transmission is detected. SOBDMC P0C65:00 Generator Position Sensor Circuit "A" Range/Performance: No Sub Type Information This DTC sets when a generator resolver failure is detected. Possible Sources
- Inverter System Controller (ISC) calibration
- Inverter System Controller (ISC)
- Z1 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CALIBRATION LEVELNOTE: Wiring overlays or repinning of circuits are NOT appropriate for DTCs P0C51 or P0C65 due to risk of hardware damage.
- Verify the Inverter System Controller (ISC) is at the latest calibration level.
Is the Inverter System Controller (ISC) at the latest calibration level?
Yes GO to Z2 No UPDATE the Inverter System Controller (ISC) to the latest calibration level. - Z2 CHECK FOR INVERTER SYSTEM CONTROLLER (ISC) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, run the Inverter System Controller (ISC) self-test.
Was DTC P0C51 or P0C65 read from the Inverter System Controller (ISC)?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new Inverter System Controller (ISC). REFER to: Inverter System Controller [SOBDMC] . No GO to Z3 - Z3 TEST DRIVE VEHICLE
- Test drive the vehicle, accelerate and decelerate quickly.
- Using a diagnostic scan tool, run the Inverter System Controller (ISC) self-test.
Are DTCs P0C65 or P0C51 present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new Inverter System Controller (ISC). REFER to: Inverter System Controller [SOBDMC] . No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
