on and the direction keyswitch is in the
desired direction
DC Drive Controller green light. See Section 6.2.
AC Drive Error code on MDI. See Section 3.3.11A
Vehicle will move only forward or only in
reverse.
Direction selector.
Batteries for loose terminals, corrosion, electrolyte level or state of
charge.

If these test procedures do not resolve your vehicle problem, contact your Columbia Dealer.
6.2 CONTROLLER TROUBLESHOOTING
DC Drive Vehicles only
The controller, located under the rear deck, has a green LED system diagnostic light (Figure 6.2.1). This LED and the
dash SYSTEM LED (Figure 3.3.1.M) can indicate a fault in the electrical system.
It is essential to observe the flashing pattern (number of blinks followed by
a pause) of the green LED light any time the vehicle is not operating as
expected. The number of blinks is very useful for your servicing dealer to
accurately and quickly diagnose any faults that exist.
Ho
wever, two of the flash codes may indicate an operation fault, and likely
do not require component changes or dealer service.
A “2 Flash fault” may indicate a start-up sequence fault. This is caused
when the vehicle direction keyswitch is not in the neutral position when the
power keyswitch is turned on. Steps to take to possibly clear this fault are:
Set the parking brake.
Turn vehicle power keyswitch to OFF.
Set direction keyswitch to N – Neutral.
Ensure the accelerator pedal is at its resting (up) position.
Turn vehicle power keyswitch to ON.
Select the desired direction on the direction keyswitch.
Release parking brake and depress accelerator.
A "7 flash fault" may indicate that the battery voltage is too high or too low
for the vehicle power system. Voltage too high occurs when rapidly
descending hills with a vehicle equipped with the ACEplus Regenerative
braking system. The electrical system creates current which causes a
spike in battery voltage.

T
o prevent this, always travel at a safe, prudent speed when driving on declines, especially with freshly charged
batteries. To possibly clear this fault turn the power keyswitch to OFF and back to ON. If there is still a “7 flash fault”,
the battery voltage may be low. Check and charge batteries or replace batteries.
If the operational fault persists or the LED is not lit or there is a “flash fault” other than 2 or 7, contact your Columbia
Dealer.
