  2. Turn ignition on. Using Tech 1 scan tool, access Central Electronics With Anti-Theft Alarm (TWICE) module. Read IGNITION +15 value. If value is ON, go to next step. If value is not ON, check for open circuit in +15 power supply circuit (Yellow/Gray wire ) to TWICE module. Repair wiring as necessary. Go to step  15 .
  3. If vehicle is equipped with A/T, go to step  8 . If vehicle is equipped with M/T, apply parking brake. Put transmission in Neutral. Attempt to start engine. If starter solenoid does not click, go to next step. If starter motor solenoid clicks, repair wiring between battery and starter, and between ground and starter. Go to step  15 .
  4. Connect test light between ground and lower terminal on fuse No. 36 (22-amp). Fuse panel is located on left side of instrument panel. Attempt to start engine. If test light comes on, go to next step. If test light does not come on, replace fuse. If fuse is okay, repair wiring to fuse. See WIRING DIAGRAMS  . Go to step  15 .
  5. Remove starter relay located in relay block, under left side of instrument panel. Connect test light between relay connector terminal No. 4 (Green/Black wire) and ground.

  6. Connect test light between relay connector terminal No. 1 (Orange wire) and ground. If test light comes on, go to next step. If test light does not come on, repair open circuit in Orange wire. Go to step  15 .
  7. Connect a jumper wire with an on/off switch between relay connector terminals No. 1 (Orange wire) and No. 2 (Yellow wire). Turn switch on. If starter operates, go to next step. If starter does not operate, connect test light between starter solenoid terminal No. 50 (Black/White wire) and starter case. If test light comes on, replace starter. If test light does not come on, repair starter ground circuit. Go to step  15 .
  8. Put transmission in Park. Apply parking brake. Attempt to start engine. If starter solenoid does not click, go to next step. If starter solenoid clicks, repair wiring between battery and starter, and between ground and starter. Go to step  15 .
  9. Connect test light between ground and lower terminal on fuse No. 36 (22-amp). Fuse panel is located on left side of instrument panel. Attempt to start engine. If test light comes on, go to next step. If test light does not come on, replace fuse. If fuse is okay, repair wiring to fuse. See WIRING DIAGRAMS  . Go to step  15 .
  10. Disconnect starter interlock Black 10-pin connector located on bracket, behind battery. See Fig 1 .

  12. Connect a jumper wire with an on/off switch between relay connector terminals No. 1 (Orange wire) and No. 2 (Yellow wire). Turn switch on. If starter operates, go to next step. If starter does not operate, connect test light between starter solenoid terminal No. 50 (Black/White wire) and starter case. If test light comes on, replace starter. If test light does not come on, repair starter ground circuit. Go to step  15 .
  13. Connect test light between relay connector terminals No. 4 (Black/White wire) and No. 5 (Brown wire). Attempt to start engine. If test light does not come on, go to next step. If test light comes on, replace starter relay. Go to step  15 .
  14. Disconnect Central Electronics With Anti-Theft Alarm (TWICE) module connector. TWICE module is located under driver's seat. Connect jumper wire between TWICE module connector terminal No. 4 (Brown wire) and ground. Attempt to start vehicle. If test light comes on, replace TWICE module. If test light does not come on, repair open circuit in Brown wire. Go to step  15 .
  15. Use scan tool and clear DTCs. Perform a starter function check. If starter operates, system is okay. If starter does not operate, replace starter.
