NOTE:
Air temperature must be between 59?100 °F (15?38 °C) during this procedure.
After the inspection, you must reset the PCM. Otherwise, the PCM will continue to stop the fuel injectors from operating.
The 12 volt battery must be in good condition and fully charged.

?1.

?2.
Check for PGM-FI, CVT, and Keyless Access system DTCs with the HDS. If you fail to enter the SYSTEM SELECTION MENU with the HDS, go to the keyless access system symptom troubleshooting "Cannot select ON mode with keyless access and with the keyless remote touching the engine start/stop switch".

Are any DTCs indicated?

     
YES
     
     
     
Go to the indicated DTC's troubleshooting.?
     
NO
     
     
     
Go to step 2.
2.
Starting system check 1:

Starting system check 1
?1.
Select All INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS.

  

?2.
With the transmission in P or N position/mode, and with the brake pedal pressed, turn the vehicle to the START mode to crank the engine.

Did the starter crank the engine?

     
YES
     
     
     
Do the PCM reset in the PGM-FI MODE menu to cancel All INJECTORS STOP with the HDS.?
     
NO
     
     
     
Go to step 3.
3.
Starting system check 2:

Starting system check 2
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Check the 12 volt battery condition. Check the electrical connections at the 12 volt battery, the 12 volt battery negative cable to the body, the engine ground cables, and the starter for looseness and corrosion. Then try starting the engine again.

Did the starter crank the engine?

     
Starter cranks normally
     
     
     
Repairing the loose connection corrected the problem. Do the PCM reset in the PGM-FI MODE menu to All INJECTORS STOP with the HDS.?
     
Starter does not crank engine at all
     
     
     
If the starter does not crank the engine at all, go to step 4.
     
Starter cranks abnormally
     
     
     
If the starter cranks the engine erratically or too slowly, go to step 6.
     
Starter overruns
     
     
     
If the starter does not disengage from the torque converter ring gear when you release the button, remove the starter, and check for the following:?
Dirty drive gear or damaged overrunning clutch
Damaged torque converter ring gear
4.
Fuse check:

Fuse check
?1.
Check the following fuses.
Fuse
Location
No. A9 (10 A)
Under-hood fuse/relay box
No. A3-5 (30 A)
No. D20 (10 A)
Under-dash fuse/relay box

Are the fuses OK?

     
YES
     
     
     
Reinstall the fuses, then go to step 5.
     
NO
     
     
     
Replace the fuse(s), and recheck. If the fuse(s) blows again, repair the short to ground on the No. A9 (10 A) fuse, the No. A3-5 (30 A) fuse, and/or the No. D20 (10 A) fuse circuit(s).?
5.
Determine possible failure area (starter, others):

Determine possible failure area (starter, others)
?1.
Make sure the transmission is in P or N position/mode.

?2.
Disconnect the following connector.
Starter S terminal 1P connector (A)

?3.
Connect terminals A and B with a jumper wire.
Terminal A
Starter S terminal 1P connector (male terminals) No. 1:
Terminal B
12 volt battery positive terminal:


Did the starter crank the engine?

     
YES
     
     
     
Check the following items in the order listed until you find the problem in the circuit:?
Check for an open or short in the wire and connectors between the under-hood fuse/relay box and the relay circuit board.
Check for an open or short in the wire and connectors between the under-dash fuse/relay box and the relay circuit board.
Check for an open or short in the wire and connectors between the relay circuit board and the PCM.
Check for an open or short in the wire and connectors between the relay circuit board and the starter.
Check for an open or short in the wire and connectors between the body control module and the PCM (STS line).
Check for an open or short in the wire and connectors between the under-hood fuse/relay box and the brake pedal position switch.
Check for an open or short in the wire and connectors between the brake pedal position switch, the body control module, and the PCM.
Check for an open or short in the wire and connectors between the transmission range switch, the body control module, and the TCM.
Check for an open or short in the wire and connectors between the transmission range switch and the TCM.
Check for poor connections or loose terminals at the transmission range switch and body ground G151.
     
NO
     
     
     
Check for an open or short in the wire and connectors between the 12 volt battery and the starter. Test or replace the starter.?
NOTE: Do not inspect the component parts inside the starter if disassembly is prohibited.
