| P0615 Starter Cut Relay Diagnosis Circuit Malfunction |
DTC (PGM-FI)
- Problem verification
-1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS.
- 3. Try to start the engine.
- 4. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame 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.
- 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 Troubleshooting: P16F3(With Auto Idle Stop System) (2016 2017 2018 2019 2020) or DTC Troubleshooting: P16F3 and P16F4 - Refer to: DTC Troubleshooting: P16F4, or DTC Troubleshooting: P16F4(With Auto Idle Stop System) (2016 2017 2018 2019 2020) .
NO
Go to step 3.
- Determine possible failure area (STRLD/ST CUT-1 RLY OUT 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.
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. C1 (7.5 A) Location Under-hood fuse/relay box Is the fuse OK?
YES
Go to step 5.
NO
Replace the No. C1 (7.5 A) fuse. Also check for a short to ground on the No. C1 (7.5 A) fuse circuit if needed.
- Open wire check (STRLD/ST CUT-1 RLY OUT line)
-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. 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 (2017 2018 2019 2020), or PCM Connector for Inputs and Outputs (2016) Is there continuity?
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 (2016 2017 2018 2019 2020) .
NO
Repair an open in the STRLD/ST CUT-1 RLY OUT wire between the PCM (A26) and starter cut relay 1.
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. C7 (7.5 A) Location Under-hood fuse/relay box Is the fuse OK?
YES
Go to step 7.
NO
Check for a short to ground on the No. C7 (7.5 A) fuse circuit. Also replace the No. C7 (7.5 A) fuse.
- Open wire check (IG1 START CUT line)
-1. Remove starter cut relay 1 (A) from the auxiliary under-hood relay block.
- 2. Turn the vehicle to the ON mode.
- 3. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Starter cut relay 1: disconnected Test point 1 Starter cut relay 1 4P socket No. 3 Test point 2 Body ground Is there battery voltage?
YES
Replace starter cut relay 1.Check the under-hood fuse/relay box if needed.
NO
Repair an open in the IG1 START CUT wire between starter cut relay 1 and the under-hood fuse/relay box.
