4 — INSTALLATION CHECKOUT
INSTALLATION CHECKOUT
Before operating the vehicle, carefully complete the following checkout proce-
dure. If you find a problem during the checkout, refer to the diagnostics and
troubleshooting section (Section 7) for further information.
The installation checkout can be conducted with or without a program-
mer. The checkout procedure is easier with a programmer. Otherwise, observe
the Status LED (located in the controller’s label area) for diagnostic codes. The
codes are listed in Section 7.
Put the vehicle up on blocks to get the drive wheels up
off the ground before beginning these tests.
Do not stand, or allow anyone else to stand, directly in
front of or behind the vehicle during the checkout.
Make sure the keyswitch is off, the throttle is in neutral,
and the forward and reverse switches are open.
Wear safety glasses and use well-insulated tools.
1. If a programmer is available, connect it to the programmer connector.
2. Turn the keyswitch on. The programmer should power up with an initial
display, and the controller’s Status LED should begin steadily blinking
a single flash. If neither happens, check for continuity in the keyswitch
circuit and controller ground.
3. Select the System Faults menu. The display should indicate “No Known
Faults.” Close the interlock switch. To do this on a walkie, pull the tiller
down to the operating position. The Status LED should continue
blinking a single flash and the programmer should continue to indicate
no faults.
If there is a problem, the LED will flash a diagnostic code and the
programmer will display a diagnostic message. If you are conducting
the checkout without a programmer, look up the LED diagnostic code
in Section 7: Diagnostics and Troubleshooting.
When the problem has been corrected, it may be necessary to cycle
the keyswitch in order to clear the fault.
4. With the interlock switch closed, select a direction and operate the
throttle. The motor should begin to turn in the selected direction. If it
does not, first verify the wiring to the forward and reverse switches. If the
