Rear E-locker quit!

[Jon]

Is there a common problem that will keep the E-locker from engaging? I threw in another black ABS computer (the box with the blue wire mod) still the same. The light just keeps blinking. What kind of readings am I supposed to get at the plug on the locker?

Have you tried all the tricks, turning slowly while engaging, going forwards and backwards, etc?

Basically you need to clean the actuator. It is a common problem and some have even bought a cable conversion.

Good point, could just be dirty. Here is the super-duper locker actuator cleaning thread.

JK, that's not the one I thought it was, looking for the right one...

Here it is. http://www.pirate4x4.com/forum/showthread.php?t=698966

Thanks guys, the Pirate4x4 by Green Truck is awesome. I'm gonna get on it now. Won't surprise me if it's full of muck sin e it spends a lot of time in water.

:thanks: Awesome link/posts, this will definitely come in handy!!

Before removing the actuator I shot power at it and didn't get any power whatsoever. Tried the other diff/lock ECU, no good. Also grounded the green/orange (spd sensor) wire to rule it out, still nothing. All voltages and grounds are correct at the diff/lock ECU. All in-cab & under-hood fuses have appropriate power on both sides. Switch is good 12v in and out when depressed.
This page mentions the HEATER RELAY http://www.ncttora.com/fsm/1996/SIL/techinfo.toyota.com/ileaf/02toyrm/02toypdf/02rmsour/2002/024runne/sa/dlsy/insp.pdf so I swapped it, no good still.

Is there another relay or fuse that I'm missing? Would someone mind engaging theirs and post the voltages at the rear connector? Thanks, I miss my locker!

Try applying 12v power to the motor leads itself. Listen to see if the motor moves to test if its the motor or not. Almost sounds like a wire is not connected or something else is stopping it in the equation. Its the non retro e-locker right? Meaning you gotta be in 4x4 etc for it to engage or did you do the bypass for it?

I would start tracing the wires after I applied voltage to the motor leads before I started going crazy ;p

On the motor lead of the 6 pin you'll see a Green red and Green by applying power to these you can turn your motor forward/reverse to see if it is the motor. Switch leads to turn it either direction. I would put a inline fuse in with one of the leads (use a 10a to protect the motor encase its 'stuck')

I've had the blue wire grounded for almost a year now, first mod. Today I checked it for continuity and it's still good so I went ahead and also grounded out the green/orange wire so that I could rule out my flakey speed sensor and not have to get down to 5mph anymore after the issue is resolved.

When applying power to the 6 pin connector, what do you use for ground? I'd try it right now but I'm on my way to sleep, work in 4hrs!

 

[Jon]

I cant find a wiring diagram for this system on my Hanes Manual or the online link previously posted. WTF?

 

[Kotrin]

They don't really post it =x

You dont need a ground for it, just take leads from a battery or even a charger, put a fuse in line of one of them to protect the motor encase its stuck. Touch the wires I was mentioning (GR and G) Here's a retro e-locker wiring diagram of the factory harness after it leaves the SUV to the connector on the locker...

I'll try to find a FSM diagram before work..
