I picked up a 88 XJ from a guy and he said he was having a few problems with it but the big one was tranny was not upshifting. So after a little research I stumbled upon the "AW4 Jeep Diagnosis" trouble shooting. Here are the measurements I came up with:
C3 - 5.78v
C8 - 11.17v
C9 - .79v
C10 - Off - .00v On - fluctuates between .00v -.79v
C11 - Power - 10.82v Comfort - .00v
C14 - 16.2
C15 - 16.2
C16 - 17.3
D2 - Closed - 4.53v Open(using pedal) - 1.01
D3 - .81v
D14 - 11.38v
D16 - 10.21v
all of the above measurements were taken in order down the chart, vehicle had a trickle charger on it and trans fluid level is good. The 7.5a fuse on the fuse block tested good via test light and the fuse on the yellow wire is good also. The previous owner claimed to have changed the trans filter and fluid looks to be new. The only other thing that I have noticed is that the Volt gauge on the dash reads in the low red when idling.
Two other questions that I have is what is the connector near the TCU connector? It has two wires one is yellow, the other is blue and yellow and looks to have a grey plastic piece in it instead of connecting to the other part of the connector. The second question is where is the resistor pack that is supposed to be inline with the fues on the yellow wire?
Thanks in advance for any help and hopefully I can get this figured out and get her back on the road.
