DTC Descriptor
DTC P0617: Starter Relay Control Circuit High VoltageCircuit/System Description
When the engine is being cranked, battery voltage is applied to the powertrain control module (PCM). On a cold engine the PCM can increase the fuel injection volume and modify ignition timing when receiving the start signal. This signal passes through the park neutral position (PNP) switch or the clutch pedal position (CPP) switch. If this signal is not detected during engine cranking, the PCM will still allow the engine to start.
Conditions for Running the DTC
| • | The battery voltage is more than 10.5 volts. |
| • | Engine speed is at least 1,000 RPM. |
| • | Vehicle speed is more than 20 km/h (12 mph). |
| • | DTC P0617 runs continuously once the above conditions have been met. |
Conditions for Setting the DTC
A high voltage is input on the Crank Signal circuit of the PCM for at least 20 seconds after starting the engine.
Action Taken When the DTC Sets
DTC P0617 is a type A DTC.
Conditions for Clearing the DTC
DTC P0617 is a type A DTC.

Circuit/System Verification
- Ignition ON, observe the scan tool Starter Switch parameter. The reading should be Released.
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
- Ignition OFF, disconnect the X1 harness connector at the PCM.
- Ignition ON, verify a test lamp does not illuminate between the crank signal circuit terminal X1-17 and ground.
- If the circuit tests normal, replace the PCM.
| ⇒ | If the test lamp illuminates, test the crank signal circuit for a short to voltage. If the circuit tests normal, test for a faulty PNP switch with AT or a faulty clutch pedal position switch with MT. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
