- Turn ignition off. Disconnect traveler module 7-pin connector. See Fig 1 . Check connector for damage. Repair and clean connector as necessary. If connector is okay, go to next step.
- Turn ignition on (engine off). Using scan tool in voltmeter mode, check voltage on traveler module 7-pin connector terminal No. 5 (White wire). If voltage is less than 10 volts, go to step 5). If voltage is more than 10 volts, go to next step.
- Disconnect scan tool from Data Link Connector (DLC). Using an external ohmmeter, check resistance of Violet/Brown wire between traveler 7-pin connector terminal No. 1 and DLC terminal No. 6. If resistance is more than 5 ohms, repair open Violet/Brown wire. If resistance is less than 5 ohms, go to next step.
- Using an external ohmmeter, check resistance of White/Black wire between traveler module 7-pin connector terminal No. 2 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open White/Black wire. If resistance is less than 5 ohms, replace traveler module.
- Remove and inspect fuse No. 11 from fuse block. See Figure . Fuse block is located on left side of dash, above hood release handle. If fuse is open, go to step 9). If fuse is okay, go to next step.
- Using scan tool in voltmeter mode, check voltage on fuse No. 11 connector (Black/Orange wire). If voltage is more than 10 volts, repair open White wire between fuse No. 11 and traveler module. If voltage is less than 10 volts, go to next step.
- Access ignition switch 7-pin connector. DO NOT disconnect ignition switch 7-pin connector. Backprobe ignition switch 7-pin connector terminal No. 5 (Black/Orange wire). If voltage is more than 10 volts, repair open Black/Orange wire. If voltage is less than 10 volts, go to next step.
- Backprobe ignition switch 7-pin connector terminal No. 4 (Pink/Black wire). If voltage is more than 10 volts, replace ignition switch. If voltage is less than 10 volts, repair open Pink/Black wire.
- Turn ignition off. Using scan tool in ohmmeter mode, check resistance of fuse No. 11 connector (White wire). If resistance is less than 5 ohms, repair short to ground in White wire and replace fuse No. 11. If resistance is more than 5 ohms, go to next step.
- Reconnect traveler module connector. Check resistance of fuse No. 11 connector (White wire). If resistance is more than 5 ohms, replace fuse No. 11. If resistance is less than 5 ohms, replace traveler module and fuse No. 11.
