Starter System Circuit Troubleshooting
Starter System Circuit Troubleshooting
NOTE:
Air temperature must be between 59?100 °F (15?38 °C) during this procedure.
The battery must be in good condition and fully charged.
1.
Starting system check 1:

Starting system check 1
?1.
Connect the following equipment:
Ammeter, 0?400 A
Voltmeter, 0?20 V (accurate within 0.1 V)

?2.

?3.
Turn the ignition switch to ON (II).

?4.
Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.

?5.
Select All INJECTORS in the PGM-FI INSPECTION menu with the HDS.

  

?6.
With the shift lever in neutral (M/T), P or N (CVT), and with the clutch pedal (M/T) or brake pedal (CVT) pressed, turn the ignition switch to START (III) 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 off with the HDS.?
     
NO
     
     
     
Go to step 2.
2.
Starting system check 2:

Starting system check 2
?1.
Turn the ignition switch to LOCK (0).

?2.
Check the battery condition. Check the electrical connections at the battery, the 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 cancel all injectors off with the HDS.?
     
Starter does not crank engine at all
     
     
     
If the starter does not crank the engine at all, go to step 3.
     
Starter cranks abnormally
     
     
     
If the starter cranks the engine erratically or too slowly, go to step 4.
     
Starter overruns
     
     
     
If the starter does not disengage from the flywheel ring gear (M/T) or torque converter ring gear (CVT) when you release the key, replace the starter, or remove and disassemble it, and check for the following:?
Dirty drive gear or damaged overrunning clutch
Damaged flywheel ring gear (M/T) or torque converter ring gear (CVT)
3.
Determine possible failure area (starter, starter circuit, Ignition switch):

Determine possible failure area (starter, starter circuit, Ignition switch)
?1.
Make sure the shift lever is in neutral (M/T), P or N (CVT).

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


?3.
Connect terminals A and B with a jumper wire.
Terminal A
Battery positive terminal
Terminal B
Starter S terminal 1P connector No. 1 (S)

Did the starter crank the engine?

     
YES
     
     
     
Check the following items in the order listed until you find the problem in the circuit:?
NOTE: After the problem in the circuit is found and repaired, do the PCM reset in the PGM-FI mode menu to cancel all injectors off with the HDS.
Check for an open or short in the BLU wire and connectors between the relay circuit board and the ignition switch.
Check for an open or short in the WHT wire, BLK/WHT wire, and connectors between the relay circuit board and the starter.
M/T: Check for an open or short in the BRN wire and connectors between the relay circuit board and clutch pedal position switch A.
CVT: Check for an open or short in the GRN wire, LT BLU wire, and connectors between the relay circuit board and the transmission range switch.
M/T: Check for poor connections or loose terminals at clutch pedal position switch A and ground G401.
CVT: Check for poor connections or loose terminals at the transmission range switch and ground G101.
Check for a faulty ignition switch.
Check for a faulty relay circuit board.
M/T: Check for a faulty clutch pedal position switch A.
CVT: Check for a faulty transmission range switch.
     
NO
     
     
     
Check for an open or short in the wire and connectors between the battery and the starter. Replace the starter, or remove and disassemble it, as necessary.?
NOTE: After the problem in the circuit is found and repaired, do the PCM reset in the PGM-FI mode menu to cancel all injectors off with the HDS.
4.
Starter test:

Starter test
?1.
While cranking the engine, check the cranking voltage and the current draw from the following service limit table.
Voltage (V)
Current (A)
8.5
380

Are the cranking voltage and the current draw within the service limits?

     
YES
     
     
     
Remove the starter, and inspect its drive gear and the flywheel ring gear (M/T) or the torque converter ring gear (CVT) for damage. Replace any damaged parts.?
NOTE: After the problem in the circuit is found and repaired, do the PCM reset in the PGM-FI mode menu to cancel all injectors off with the HDS.
     
NO
     
     
     
Replace the starter, or remove and disassemble it, and check for these problems:?
NOTE: After the problem in the circuit is found and repaired, do the PCM reset in the PGM-FI mode menu to cancel all injectors off with the HDS.
Drag in the starter armature
Shorted armature winding
Excessive drag in the engine
Open circuit in the starter armature commutator segments
Excessively worn starter brushes
Open circuit in the starter brushes
Dirty or damaged helical splines or drive gear
Faulty overrunning clutch
