MATT ERR:
The lift’s Threshhold Plate has pressure on it. There may be a load or occupant on it, or it
may need to be adjusted.
Corrective Actions:
1. Make sure the MAT switch is adjusted correctly. If required, do the MAT SWITCH
ADJUSTMENT in this manual.
2. If adjustment does not solve the problem, go to the diagnostic mode on the Control-
ler and check the “Mat” switch code (see DIAGNOSTICS). The 6th digit in the fi rst
set of binary codes (11110001) indicates the “Mat” switch. Push the actuator lever on
each of the 2 MAT switches (only one at a time). If the digit changes from 0 to 1 or
from 1 to 0, then the wiring connections and switch are good.
3. If the Controller (FIG. 72-1) still reads MAT SW, replace the Controller.
LOCK ERR:
Lift is not stowed, and the interlock signal from the vehicle is not reaching the Controller.
For the vehicle interlock to send a signal to the Lift, the vehicle transmission must be in
park or neutral, emergency or service brakes must be set, and Lift switch or other controls
(as equipped) must be set correctly. Lift can be operated until stowed. Then the Lift cannot
be operated until it receives the interlock signal from the vehicle.
Corrective Actions:
1. Check all the conditions, controls, and settings on the vehicle interlock and then
check the interlock connections to the Lift (see ELECTRICAL SYSTEM DIAGRAM).
2. Disconnect the vehicle interlock wire (white with red stripe) from the Lift (see ELEC-
TRICAL SYSTEM DIAGRAM). (The vehicle interlock wire is on the same side as
the pump.) Then connect the wire to ground. If the LOCK ERR reading is gone from
the Controller (FIG. 72-1), the Lift interlock is operating correctly, get the vehicle
interlock repaired.
LOCKED:
This is a normal reading on the Controller (FIG. 72-1) if the Lift is stowed and vehicle is
being driven. It indicates the Lift cannot be operated because it is not getting the interlock
signal from the vehicle. The vehicle normally sends the interlock signal to the Lift when ve-
hicle transmission is in park or neutral, emergency or service brakes are set, and Lift switch
or other controls (as equipped) are set correctly. For the Lift to operate, the Controller must
display a STOWED (see STOWED*, STOWED.*, and STOWED).
