Starter Circuit Troubleshooting
  1. Make sure the transmission is in Neutral, and set the parking brake. Disconnect the connector from the starter solenoid S terminal. Connect a jumper wire from the battery positive terminal to the solenoid terminal.
Did the starter crank the engine?
YES -
Go to Step 19 .
NO -
Remove the starter, and repair or replace as necessary.■
  1. Check the following items in the order listed until you find the open circuit:
    • The WHT wire and connectors between the under-dash fuse/relay box and the starter cut relay 2.
    • The RED and BLK/WHT wire and connectors between the starter cut relay 2 and the starter.
  1. While cranking the engine, check the cranking voltage and the current draw.
Is the cranking voltage greater than or equal to 8.7 V (KG, KS models), 8.0 V (KE model) and the current draw less than or equal to 230 A (KG, KS models), 200 A (KE model)?
YES -
Go to Step 21 .
NO -
Replace the starter, or remove and disassemble it, and check for the following:
  • Drag in the starter armature
  • Shorted armature winding
  • Excessive drag in the engine
  1. Check the engine speed while cranking the engine.
Is the engine speed above 100 rpm (min −1 )?
YES -
Go to Step 22 .
NO -
Replace the starter, or remove and disassemble it, and check for the following:
  • Open circuit in the starter armature commutator segments
  • Excessively worn starter brushes
  • Open circuit in the commutator brushes
  • Dirty or damaged helical splines or drive gear
  • Faulty drive gear clutch
  1. Remove the starter, and inspect its drive gear and the flywheel ring gear for damage. Replace any damaged parts.
  1. Select ECM reset to cancel ALL INJECTORS OFF on the HDS.
