Special Jack Error Codes

To clear one of the error codes listed below:
1. Correct or otherwise repair the issue (see the table below).
Note: In order to clear the special jack error code the jacks need
to be "homed." In order to "home" jacks, each jack MUST be
able to retract a minimum of 6".
2. Extend all jacks to reach the 6" of minimum retract needed.
A. Press "FRONT" (Fig. 22G) to extend the front jacks (if
required).
B. Press "REAR" (Fig. 22J) to extend the rear jacks (if
required).
C. Press "LEFT" and "RIGHT" (Fig. 22H and Fig. 22I)
simultaneously to extend the middle jacks (if equipped and
required).
3. Press and hold the retract button until all of the jacks begin to
retract. The jacks will retract until they reach the hard current
limit.
4. The jacks are now "homed" and the special jack error code
will be cleared.
Note: If the jacks do not retract, an error should display on
the touch pad screen. This is typically caused by wiring
interruption.
