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 Values Unit Values Unit STARTER CUT RELAY Less than 1.3 V Do the current condition(s) match the threshold?
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.
- 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 3.
NO
Go to step 5.
- Determine possible failure area (START DIAG line, others)
-1. Turn the vehicle to the ON mode.
-2. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit STARTER CUT RELAY Less than 1.3 V Do the current condition(s) match the threshold?
YES
Go to step 4.
NO
Go to step 5.
- Relay check
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Remove starter cut relay 2 (A) from the driver's under-dash fuse/relay box.
-3. Test starter cut relay 2 .
Is the relay OK?
YES
Replace the driver's under-dash fuse/relay box , then do the repair verification.
NO
Replace starter cut relay 2, then do the repair verification.
- Determine possible failure area (PCM, others)
-1. Remove starter cut relay 2 (A) from the driver's under-dash fuse/relay box.
-2. Jump the SCS line with the HDS.
-3. Disconnect the following connector.
PCM connector A (51P) -4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Starter cut relay 2: disconnected Test circuit START DIAG Test point 1 PCM connector A (51P) No. 26 (PNK) Test point 2 Body ground Is there continuity?
YES
Go to step 6.
NO
Update the PCM if it does not have the latest software, or substitute a known-good PCM , then do the repair verification.
- Shorted wire check (START DIAG line)
-1. Disconnect the following connector.
Driver's under-dash fuse/relay box connector F (32P) -2. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Starter cut relay 2: disconnected PCM connector A (51P): disconnected Driver's under-dash fuse/relay box connector F (32P): disconnected Test circuit START DIAG Test point 1 PCM connector A (51P) No. 26 (PNK) Test point 2 Body ground Is there continuity?
YES
Repair a short in the START DIAG wire between the driver's under-dash fuse/relay box and the PCM (A26), then do the repair verification.
NO
Replace the driver's under-dash fuse/relay box , then do the repair verification.
- Repair verification
-1. Reconnect all connectors.
-2. Exit the SCS mode with the HDS.
-3. Turn the vehicle to the ON mode.
-4. Reset the PCM with the HDS .
Reset PCM
-5. Do the PCM idle learn procedure.
-6. Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0616 indicated?
YES
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 PCM was updated, substitute a known-good PCM , then recheck. If the PCM was substituted, go to step 1.
NO
Troubleshooting is complete. If the PCM was substituted, replace the original PCM . If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
