Troubleshooting Hints - Export Harness
TRY FOLLOWING CHECKS BEFORE DOING SYSTEM CHECK1. If the Turn Lamps do not work, check Trunk Compartment Fuse Block Fuse All. If open, check for a short to ground in CKT 139.
2. If the Hazard Lamps do not work, check Engine Compartment Fuse Block Fuse B1. If open, check for a short to ground in CKT 140.
3. If the Stoplamps do not work, check Engine Compartment Fuse Block Fuse B3. If open, check for a short to ground in CKT 540.
4. If LH Park Lamps do not work, check Trunk Compartment Fuse Block Fuse D13.
5. If RH Park Lamps do not work, check Trunk Compartment Fuse Block Fuse D11.
6. If Cornering Lamps do not work, check Engine Compartment Fuse Block Fuse A3.
7. If one of the Turn Indicators goes on when the Park Lamps are turned "ON", check the Front Park/Turn Lamps on that side for open or poor connection.
8. If Turn Lamps stay "ON" (do not flash) in both Turn Left and Turn Right positions, replace the Turn Flasher Module.
9. For any of the following symptoms, replace the Turn/Hazard Switch Assembly:
^ Turn Signal Switch will not turn "ON"/"OFF".
^ All Turn/Hazard/Stoplamps do not work and C202 is firmly mated.
^ Some Turn Lamps work and all Hazard Lamps work.
^ Some Hazard Lamps work and all Turn Lamps work.
^ Hazard Lamps do not turn "OFF".
10. If Hazard Lamps stay "ON" (do not flash) in "Hazard", but Stoplamps operate normally, replace the Hazard Flasher.
11. If Stoplamps do not turn "OFF" adjust/replace the Stop/BTSI/Cruise Brake Switch.
12. If a Turn Indicator does not light but the Turn Signal works, check the bulb, connections and wiring to the indicator.
13. If only one lamp does not operate, check the lamp, socket and related wiring for opens or corrosion (see schematic).
14. If Parking Lamps stay "ON" and Headlamps stay at full intensity with daylight conditions check for an obstruction covering the Twilight Photocell (Refer Headlamp).
15. Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
16. Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
17. Check that grounds G100, G101, G301, G304, G401 and G402 are clean and tight.
18. Before component replacement, check for poor connections at related component and in-line harness connector terminal connections.
