Re: access instrument cluster connector & speedo sensor troubleshooting
Well, stalling in neutral is because you have the speed sensor
disconnected.
If you reconnect it and it stops stalling, the sensor is likely working.
The sensor generates it's own pulses. Just spin it by hand with a meter
on it. 8 pulses per revolution off pin 1 and 2 likely.
'What' is the speedometer doing or not doing anyway?
To pull the codes, you need to hook everything back up and drive it for
a bit.
Then stop, rev it ti 2500 and let it down to idle and cycle everything
like the AC and if an automatic all the gears.
Then shut it down and turn the key on, off, on, off, on and count the
flashes on the dash light. It will flash a sequence, then pause, then
flash again. The final flash will be a 5 and a 5 or code 55 that means
no more codes.
If you get a code 15, the speed sensor or it's circuit is bad.

SAME DEAL BY DOING MANUALLY WITH A METER. TO BACK UP WHAT THE OBS IS
SHOWING, GO AHEAD AND CHECK TO SEE IF 5 VOLTS ARE PRESENT FROM THE
CABLE.
YES: SENSOR BAD OR GROUND WIRE NOT CONNECTED.
NO: 5V SHORTED OR BAD CONNECTION AT THE MULTICONNECTOR.

Re: access instrument cluster connector & speedo sensor troubleshooting
Right, now I remember that hall sensor has to be plugged in to test it
just switches the power to pulses. A hand turn should give the pulses
though, same as a distributor one.
If the ground tag is bad, that is likely a stud on the rear passenger
side of the block with a bunch of small black wires on it. The YJ has
one more ground tag on the e-brake frame, but that one usually kills the
fuel pump.

Re: access instrument cluster connector & speedo sensor troubleshooting
Right, now I remember that hall sensor has to be plugged in to test it
just switches the power to pulses. A hand turn should give the pulses
though, same as a distributor one.
If the ground tag is bad, that is likely a stud on the rear passenger
side of the block with a bunch of small black wires on it. The YJ has
one more ground tag on the e-brake frame, but that one usually kills the
fuel pump.
