I installed Spicer's Ultimate Dana 44, it has the stock locker connection in but no sensor.
So, the Jeep's sensor connector just hangs there. When it locks, the rear is solid and the front flashes, not really a big deal but….
I tested the wires.
The sensor wires, on one leg it has 12vdc so when the sensor closes –pulls out- “locker is locked” it shorts the two sensor wires together to indicate locked.
The locker wires, one of those has 12vdc on it as well to energize the locker itself.
My dumb ass thinks…. “Why don’t I just stick the 12vdc from the locker to the return wire of the sensor wires and that should Lock the locker and indicate a solid Front Locker light on the dash. This will be great!”
I did that and - NOT!!!
I must have burned up or de-programmed something because:
1. It will not indicate 4wd in HI or LOW
2. It will not shift out of first gear
3. The fuel gage indicates empty with the gas pump indicator
4. Dash brake light on constant
5. Flashing Sway Bar dash indicator
6. Check Engine dash indicator
7. & I cannot actuate the lockers or sway bar disco
I can use my JKS programmer to set tire and gear changes as well as pull and clear DTC’s
Some DTC’s are: P0463 Fuel level sensor 1 circuit high, U0414 Implausible data received from FDCM, C1008 Brake fluid level circuit high and C1405 Transfer case range position sensor circuit high.
I know guys…. I want to kick my own ass. So, besides: “Dude you really fucked up!” And before I call the dealership to schedule an ass rape, has anyone dealt with or know what could be wrong? Or what will probably need replaced?
BTW, it's an AutoMagic trans.
