   P0615 Starter Cut Relay Diagnosis Circuit Malfunction

   Is DTC P0615 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   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 - Refer to: How to Troubleshoot the Fuel and Emissions Systems .

2. DTC check

   - 1. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   P16F3 Starter Cut Relay 1 Control Circuit Low Voltage
   P16F4 Starter Cut Relay 2 Control Circuit Low Voltage

   Are DTC P16F3 and P16F4 indicated?

   YES 

   Go to the troubleshooting for DTC P16F3 - Refer to: DTC P16F3 (Without Auto Idle Stop System) (2016 2017 2018 2019 2020),DTC P16F3 (Touring) (2016 2017 2018)

   and P16F4 - Refer to: DTC P16F4 (Touring) (2016 2017 2018), or DTC P16F4 (Without Auto Idle Stop System) (2016 2017 2018 2019 2020) .

   NO 

   Go to step 3.

3. Determine possible failure area (STRLD line, others)

   - 1. Turn the vehicle to the ON mode.

   - 2. Clear the DTC with the HDS.

   - 3. Try to start the engine.

   Does the engine start?

   YES 

   Go to step 4.

   NO 

   Go to step 6.

4. Fuse check

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

   - 2. Check the following fuse.

   Fuse	No. B17 (7.5 A)

   Location

   Auxiliary under-hood fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 5.

   NO 

   Replace the No. B17 (7.5 A) fuse. Also check for a short to ground on the No. B17 (7.5 A) fuse circuit if needed.

5. Open wire check (STRLD line)

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

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

   - 3. Jump the SCS line with the HDS, and wait more than 1 minute.

   - 4. Disconnect the following connector.

   PCM connector A (51P)

   - 5. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Starter cut relay 1: disconnected
   	PCM connector A (51P): disconnected
   Test point 1	Starter cut relay 1 4P socket No. 1
   Test point 2	PCM connector A (51P) No. 26 - Refer to: PCM Connector for Inputs and Outputs(6-Speed A/T) (2016 2017 2018 2019 2020) .

   Is there continuity?

   YES 

   The STRLD wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM - Refer to: PCM Removal and Installation (6-Speed A/T), ('16-'18 9-Speed A/T) .

   NO 

   Repair an open in the STRLD wire between the PCM (A26) and starter cut relay 1.

6. Fuse check

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

   - 2. Check the following fuse.

   Fuse	No. C7 (15 A)
   Location	Under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 7.

   NO 

   Check for a short in the IG1 ACG wire between the No. C7 (15 A) fuse in the under-dash fuse/relay box and the auxiliary under-hood fuse/relay box. If the wire is OK, replace the under-dash fuse/relay box. Also replace the No. C7 (15 A) fuse.

7. Open wire check (IG1 ACG line)

   - 1. Remove starter cut relay 1 (A) from the auxiliary under-hood fuse/relay box.

   - 2. Disconnect the following connector.

   Under-dash fuse/relay box connector F (18P)

   - 3. Connect terminals A and B with a jumper wire.

   Terminal A	Under-dash fuse/relay box connector F (18P) No. 11
   Terminal B	Body ground

   - 4. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Starter cut relay 1: disconnected
   	Under-dash fuse/relay box connector F (18P): disconnected
   	Under-dash fuse/relay box connector F (18P) No. 11: jumped to body ground
   Test point 1	Starter cut relay 1 4P socket No. 3
   Test point 2	Body ground

   Is there continuity?

   YES 

   Go to step 8.

   NO 

   Repair an open in the IG1 ACG wire between starter cut relay 1 and the under-dash fuse/relay box.

8. Relay check

   - 1. Test starter cut relay 1.

   Is the relay OK?

   YES 

   Replace the Under-dash fuse/relay box .

   NO 

   Replace starter cut relay 1.
