DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition SOBDMC P0C67:00 Generator Position Sensor Circuit "A" High: No Sub Type Information This DTC sets when a short to power is detected in the generator resolver circuit. Possible Sources
- Wiring, terminals or connectors
- Transmission assembly
- Inverter System Controller (ISC) calibration
- AC1 CHECK THE INVERTER SYSTEM CONTROLLER (ISC) CALIBRATION LEVELNOTE: Wiring overlays or repinning of circuits are NOT appropriate for DTC P0C67 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 AC2 No UPDATE the Inverter System Controller (ISC) to the latest calibration level. - AC2 CHECK FOR CMDTC (CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODE) P0C67
- Ignition ON.
- Using a diagnostic scan tool, retrieve all Inverter System Controller (ISC) CMDTCs.
Was CMDTC P0C67 read from the Inverter System Controller (ISC)?
Yes GO to AC3 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. - AC3 VISUAL INSPECTION OF THE LOW VOLTAGE SYSTEM
- Ignition OFF.
- De-energize the high voltage system. REFER to: High Voltage System De-energizing .
- Visually inspect all the low voltage cables.
- Make sure all the low voltage connectors are correctly and securely connected.
- Examine all the low voltage cables and connectors for damaged, burned or overheated insulation and loose or broken conditions.
Is a concern present?
Yes REPAIR as necessary. CLEAR the Inverter System Controller (ISC) DTCs and REPEAT the self-test. No GO to AC4 - AC4 CHECK THE GS1 CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition ON.
- Measure and record:
Positive Lead Measurement / Action Negative Lead C1111-32 Ground
Is any voltage present?
Yes With the aid of the wiring diagram, REPAIR the short circuit. CLEAR the Inverter System Controller (ISC) DTCs and REPEAT the self-test. No GO to AC5 - AC5 CHECK THE GS3 CIRCUIT FOR A SHORT TO VOLTAGE
- Measure and record:
Positive Lead Measurement / Action Negative Lead C1111-22 Ground
Is any voltage present?
Yes With the aid of the wiring diagram, REPAIR the short circuit. CLEAR the Inverter System Controller (ISC) DTCs and REPEAT the self-test. No GO to AC6 - Measure and record:
- AC6 CHECK FOR CORRECT INVERTER SYSTEM CONTROLLER (ISC) OPERATION
- Ignition OFF.
- Disconnect and inspect all Inverter System Controller (ISC) connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the Inverter System Controller (ISC) connectors. Make sure they seat and latch correctly.
- Connect HF 45 Transmission C1111.
- Ignition ON.
- Operate the system and determine if the concern is still present.
Is the concern still 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, GO to Pinpoint Test Q (In step Q4 continue through to step Q5 regardless of DTC presence.) No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
