1.13. The forward / reverse actuator is connected to
the shift wedge. Depending on which side of the
actuator vacuum is provided to, the actuator
moves the shift wedge in one direction or the
other. See Figure 1.13.
1.14. The differential lock actuator is mounted lower
and farther back on the transaxle.
See Figure 1.14.

SELF DIAGNOSTICS
2.1.
In the event of system malfunction, refer to the
fault code list.
2.2.
If the Big Country does not shift properly, the
ESM will let the operator know there is a prob-
lem using the following table of fault codes.
Once the operator selects a gear, the instrument
panel will illuminate a gear light, or a combina-
tion of gear lights. DO NOT PRESS THE
ACCELERATOR UNTIL THE GEAR
SELECTED IS VERIFIED ON THE INSTRU-
MENT PANEL. These lights can be used to
determine if the vehicle shifted properly, or if
there is a shifting issue. The letter on the far left
represents the gear the vehicle was in prior to
shifting:
* - Indicates the lights will flash for 5 seconds and an
audible tone will sound. During that time a shift will not
be allowed by the ESM. Once the lights stop flashing
the ESM will allow for shifting.
Example - The vehicle was in reverse (look at row
starting with "R"). The gear selected was forward (look
at "F" in "Gear Selected" row). The "Light Code"
flashed on the instrument panel is "RF", which corre-
sponds with "Fault code 3". Looking up "code 3" in the
"Fault Codes Defined" section will list the potential
problems.
