FAULT CODES DEFINED
Code 1: “REVERSE” and “NEUTRAL” lights flash
Action A - Vehicle is in “FORWARD” and operator attempts a shift to “NEUTRAL”
•
This lets the operator know the vehicle was supposed to go to neutral, but
probably
ended up in reverse.
The vacuum actuator probably shifted the transmission into reverse because the signal to stop at neutral
was not present. However, it may not have shifted out of forward if there was mechanical binding, or loss
of vacuum.
Action B – Vehicle is in “NEUTRAL” and operator attempts a shift to “REVERSE”
•
This lets the operator know the vehicle was supposed to go to reverse and it
probably
did, but it was not
verified because the Neutral Sensor never opened (due to mechanical binding or a damaged sensor).
Code 2: “FORWARD” and “NEUTRAL” lights flash
Action C -
Vehicle is in “REVERSE” and operator shifts to “NEUTRAL”
•
This lets the operator know the vehicle was supposed to go to neutral, but
probably
ended up in forward.
The vacuum actuator probably shifted the transmission into forward because the signal to stop at neutral
was not present. However, it may not have shifted out of reverse if there was mechanical binding, or loss
of vacuum.
Action D – Vehicle is in “NEUTRAL” and operator attempts a shift to “FORWARD”
•
This lets the operator know the vehicle was supposed to go to forward and it
probably
did, but it was not
verified because the Neutral Sensor never opened (due to mechanical binding or a damaged sensor).
Code 3: “FORWARD” and “REVERSE” lights flash
Action E
-
Vehicle is in “FWD” or “REV” and the operator shifts to the opposite direction
•
This lets the operator know the vehicle was supposed to shift to the opposite direction and it
probably
did,
but the module was not able to verify. This may have occurred because the neutral sensor is damaged,
there is mechanical binding, or a loss of vacuum.
Code 4: “FORWARD” and “NEUTRAL” and “REVERSE” lights flash
Action F -
Vehicle is in “FWD/NEU” or “REV/NEU” and the operator shifts to “NEUTRAL”
•
If the operator experiences a fault relative to not finding neutral (“fwd/neu” or “rev/neu”) and then tries a
second time to shift to neutral, all lights will flash. This is a warning to shut off the vehicle, manually shift to
neutral, and restart the vehicle in a known gear (neutral).
WARNING:
If the vehicle is shut off under a fault condition, before the vehicle will start again the Neutral Sensor
must function properly AND the vehicle will have to be manually shifted into “NEUTRAL”.
To manually shift the vehicle into “NEUTRAL”, proceed
as follows:
•
With the vehicle shut off, apply the parking brake.
•
Raise and secure cargo box, if manual lift.
•
Place shift lever into the neutral position. See
Figure 23.
•
Lower and latch cargo box.
