Per the 2003 Service manual regarding diagnosing locker issues:
(6) Disconnect the rear and/or front locker indicator switch pigtail harness connector from the rear or front axle jumper harness connector. Check for continuity between the ground circuit cavity of the rear or front axle jumper harness connector and a good ground. There should be continuity. If OK, go to Step 7. If not OK, repair the open ground circuit between the rear or front axle jumper harness connector for the rear or front locker indicator switch and ground (G105) as required.
(7) Check for continuity between the ground circuit and the rear or front locker indicator switch sense circuit cavities of the rear or front locker indicator switch pigtail harness connector. There should be continuity with the axle locker engaged, and no continuity with the axle locker disengaged. If OK, go to Step 8. If not OK, replace the faulty rear or front locker indicator switch.
I'm confused. What is the difference between the two? It seems to be saying the same thing except for engaging the lockers.
Also, how do you engage lockers that are not working?
(9) Check for continuity between the rear or front locker indicator switch sense circuit cavities of the rear or front axle jumper harness connector for the locker indicator switch and the instrument cluster. There should be continuity. If OK, use a DRBIIIt scan tool to perform additional testing of the instrument
cluster. Refer to the appropriate diagnostic information. If not OK, repair the open rear or front locker indicator switch sense circuit between the rear
or front axle jumper harness connector for the locker indicator switch and the instrument cluster as required.
This makes no sense to me. Am I checking between the locker switch and the instrument cluster? the locker switch? Both? Neither?
Can someone dumb this down for me?
