  1. Turn ignition off. Disconnect mode switch 8-pin harness connector. Mode switch is located on shift lever base. Turn ignition on. Check voltage between body ground and mode switch harness connector terminal No. 6 (Black/Red wire). If battery voltage is present, go to step  3 . If battery voltage is not present, go to next step.
  2. Repair open or short in circuit between mode switch harness connector terminal No. 5 (Blue/Yellow wire) or No. 6 (Black/Red wire) and TCM harness connector "B" terminal No. 13 (Black/Red wire). See WIRING DIAGRAMS  .
  3. Check voltage between mode switch harness connector terminals No. 1 (Black wire) and No. 6 (Black/Red wire). If battery voltage is not present, go to next step. If battery voltage is present, go to step  5 .
  4. Repair open in circuit between mode switch harness connector terminal No. 1 (Black wire) and ground connector. If circuit is okay, repair poor ground.
  5. Check continuity between mode switch harness connector terminals No. 1 (Black wire) and No. 6 (Orange wire) while moving shift lever back and forth between "D4" and sport shift gate. Reading should change from continuity to no continuity. If reading changes, go to next step. If reading does not change, replace mode switch.
