[xj40] Alternative to Rotary Switch Tool?

I am attempting to correct a Fail Code 69 (Drive/Neutral Input
Circuit). I have not attempted to adjust the shift linkage yet due
to the non-availabilty of the Rotary Switch Adjustment Tool #
JD.161. I know this tool isn’t required to adjust the shift
linkage, but would like to verify/adjust the rotary switch after I
perform the linkage adjustment. Since this tool/gauge is quite
expensive and will probably never be used (by me) again, Does
anyone know of an alternate method of adjusting the rotary switch?–

1st guess is you’ve got a shift cable issue,
not a switch adjustment one but…

When I replaced the cable on my '93, I dId the
work at night. With the ignition on (engine
not running) I put the transmission in
reverse, the shifter in reverse and adjusted
the switch untIl the backup lights illuminated.
Locjedbthings down.

Worked for me.–

Thanks for the reply.
Everything APPEARS to be fine with the shift cable. The reverse
lights work, all gears mesh when manually shifted in the ‘‘J’’ gate,
drives and shifts normally at all speeds. I had a VCM code 69
(Drive/Neutral input circuit) error. I cleared the code (has not
recurred) but there are some issues still unresolved.

  1. Check engine light is on (No VCM Code)
  2. When cranking, I usually have to slightly move the shift lever
    (while in Park)to get it to start.
  3. While driving, sometimes (frequently) I hear a (somewhat)loud
    click coming from the gear shift area when I apply the brakes.

I want to check the shift cable adjustment first, but suspect the
rotary switch is the primary cause of the problem.
As with most adjustments, if I adjust one component it will require
adjustment of another. I would rather have the necessary tools to
check both at the same time.

Any suggestions on an alternative to the costly ‘‘special’’ tool is
appreciated.–

Hi Ray.
Not having a '94 myself this may be erroneous but I believe the '94 have an
interlock between the brake pedal and gearlever? I.e. the brake has to be
pressed before the lever can be moved?
If so perhaps this is the source of the click you are hearing?
I also had a VCM code thrown a few weeks ago which resulted in a number
being displayed, this was for the ISCV this caused the trans to go into limp
mode. once I had reset the ISCV the trans came back to life. However before
this occurred the check eng light was illuminated but I could not retrieve a
fault code.
Once the ISCV was reset the check light extinguished.
Go figure?
