DTC P0617 : Starter Cut Relay Diagnosis Circuit High Voltage

NOTE: Before you troubleshoot, review the general troubleshooting information - Refer to: How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016), or How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems .

DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
P0617 Starter Cut Relay Diagnosis Circuit High Voltage

DTC (PGM-FI)

Problem verification

-1. Turn the vehicle to the ON mode.

- 2. Clear the DTC with the HDS.

- 3. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
STARTER CUT RELAY	More than 4.67	V

Do the current condition(s) match the threshold?

YES

The failure is duplicated. Go to step 2.

Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at starter cut relay 1, starter cut relay 2, and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

Determine possible failure area (STRLD/ST CUT-1 RLY OUT line, others)

-1. Turn the vehicle to the OFF (LOCK) mode.

- 2. Remove the following fuse.

Fuse	No. C1 (7.5 A)
Location	Under-hood fuse/relay box

- 3. Turn the vehicle to the ON mode.

- 4. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
STARTER CUT RELAY	More than 4.67	V

Do the current condition(s) match the threshold?

YES

Go to step 4.

The STRLD/ST CUT-1 RLY OUT wire is OK. Go to step 3.

Relay check
-1. Turn the vehicle to the OFF (LOCK) mode.

- 2. Remove starter cut relay 1 (A) from the auxiliary under-hood relay block.

- 3. Test starter cut relay 1.

Is the relay OK?

YES

Repair a short to power in the STRLD/ST CUT-1 RLY OUT wire between the No. C1 (7.5 A) fuse in the under-hood fuse/relay box, starter cut relay 1, and starter cut relay 2. If needed, replace the under-hood fuse/relay box .

NO

Replace starter cut relay 1.

Shorted wire check (STRLD/ST CUT-1 RLY OUT line to power)

-1. Turn the vehicle to the OFF (LOCK) mode.

- 2. Remove starter cut relay 1 (A) from the auxiliary under-hood relay block.

- 3. Jump the SCS line with the HDS.

- 4. Disconnect the following connector.

PCM connector A (51P)

- 5. Turn the vehicle to the ON mode.

- 6. Measure the voltage between test points 1 and 2.

Test condition	Vehicle ON mode
	Starter cut relay 1: disconnected
	No. C1 (7.5 A) fuse: removed
	PCM connector A (51P): disconnected
Test point 1	PCM connector A (51P) No. 26 - Refer to: PCM Connector for Inputs and Outputs (2014 2015), or PCM Connector for Inputs and Outputs (2016), or PCM Connector for Inputs and Outputs (2017 2018 2019 2020)
Test point 2	Body ground

Is there about 0.1 V or less?

YES

The STRLD/ST CUT-1 RLY OUT wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM - Refer to: PCM Removal and Installation (2014 2015), or PCM Removal and Installation (2016) . '

Repair a short to power in the STRLD/ST CUT-1 RLY OUT wire between the PCM (A26) and the No. C1 (7.5 A) fuse in the under-hood fuse/relay box.
