Starter Inspection: Notes

On-vehicle Inspection 

1. Verify that the battery is fully charged.
2. The starter is normal if it rotates smoothly and without any noise when the engine is cranked.
   • If the starter does not operate, inspect the following: 
     • Remove the starter, and inspect the starter unit.
     • Inspect the related wiring harnesses and the ignition switch.
     • Verify any TCM DTCs to check whether there is a malfunction with the selector lever in determining the shift position. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (GW6A-EL, GW6AX-EL)] .)

No-load Test 

1. Verify that the battery is fully charged.
2. Connect the starter, battery, and a tester as shown in the figure.
