1.
Problem verification:

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
More than 3.2
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 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.
Determine possible failure area (START DIAG line, others):

Determine possible failure area (START DIAG line, others)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Remove the following fuse.
Fuse
No. B25 (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.

Do the current condition(s) match the threshold?

     
YES
     
     
     
Go to step 4.
     
NO
     
     
     
The START DIAG wire is OK. Go to step 3.
3.
Relay check:

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

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


?3.
Test starter cut relay 1.

Is the relay OK?

     
YES
     
     
     
Repair a short to power in the ST RLY 1 TO 2 wire between the No. B25 (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.?
4.
Shorted wire check (START DIAG line to power):

Shorted wire check (START DIAG line to power)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS.


?3.
Disconnect the following connector.
PCM connector A (51P)

?4.
Turn the vehicle to the ON mode.

?5.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
Starter cut relay 1: disconnected
No. B25 (7.5 A) fuse: removed
PCM connector A (51P): disconnected
Test point 1
PCM connector A (51P) No. 47
Test point 2
Body ground

Is there about 0.1 V or less?

     
YES
     
     
     
The START DIAG wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0617 goes away and the PCM was updated, troubleshooting is complete. If DTC P0617 goes away and the PCM was substituted, replace the original PCM.?
     
NO
     
     
     
Repair a short to power in the START DIAG wire between the No. B25 (10 A) fuse in the under-hood fuse/relay box and the PCM (A47).?
