   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 the driver's under-dash fuse/relay box, 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.

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

   Is DTC P16F3 and P16F4 indicated?

   YES 

   Go to the troubleshooting for DTC P16F3 - Refer to: DTC Troubleshooting: P16F3, or DTC Troubleshooting: P16F3(With Auto Idle Stop System) (2016) and P16F4 - Refer to: DTC Troubleshooting: P16F4(With Auto Idle Stop System) (2016), or DTC Troubleshooting: P16F4 .

   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. D25 (7.5 A)
   Location	Driver's under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 5.

   NO 

   Replace the No. D25 (7.5 A) fuse. Also check for a short to ground on the No. D25 (7.5 A) fuse circuit if needed.

5. Open wire check (STRLD line)

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

   - 2. Jump the SCS line with the HDS.

   - 3. Disconnect the following connectors.

   Driver's under-dash fuse/relay box connector F (32P) - Refer to: Driver's Under-Dash Fuse/Relay Box Removal and Installation, or Passenger's Under-Dash Fuse/Relay Box Removal and Installation

   PCM connector A (51P) - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or 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)

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

   Terminal A	Driver's under-dash fuse/relay box connector F (32P) No. 25 (WHT)
   Terminal B	Body ground

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

   Test condition	Vehicle OFF (LOCK) mode
   	Driver's under-dash fuse/relay box connector F (32P): disconnected
   	Driver's under-dash fuse/relay box connector F (32P) No. 25: jumped to body ground
   	PCM connector A (51P): disconnected
   Test circuit	STRLD
   Test point 1	PCM connector A (51P) No. 26 (PNK)
   Test point 2	Body ground

   Is there continuity?

   YES 

   The STRLD 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) .

   NO 

   Repair an open in the STRLD wire between the driver's under-dash fuse/relay box and the PCM (A26). If the wire is OK, replace the driver's under-dash fuse/relay box - Refer to: Driver's Under-Dash Fuse/Relay Box Removal and Installation, or Passenger's Under-Dash Fuse/Relay Box Removal and Installation .

6. Fuse check

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

   - 2. Check the following fuse.

   Fuse	No. D24 (7.5 A)
   Location	Driver's under-dash fuse/relay box

   Is the fuse OK?

   YES 

   Go to step 7.

   NO 

   Replace the driver's under-dash fuse/relay box - Refer to: Driver's Under-Dash Fuse/Relay Box Removal and Installation, or Passenger's Under-Dash Fuse/Relay Box Removal and Installation . Also replace the No. D24 (7.5 A) fuse.

7. Open wire check (IG1 ACG line)

   -1. Remove starter cut relay 1 (A) from the driver's under-dash fuse/relay box.

   - 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 circuit	IG1ACG
   Test point 1	Starter cut relay 1 4P socket No. 3

   Is there battery voltage?

   YES 

   Go to step 8.

   NO 

   Replace the driver's under-dash fuse/relay box - Refer to: Driver's Under-Dash Fuse/Relay Box Removal and Installation, or Passenger's Under-Dash Fuse/Relay Box Removal and Installation .

8. Relay check

   -1. Test starter cut relay 1.

   Is the relay OK?

   YES 

   Replace the driver's under-dash fuse/relay box - Refer to: Driver's Under-Dash Fuse/Relay Box Removal and Installation, or Passenger's Under-Dash Fuse/Relay Box Removal and Installation .
