TROUBLESHOOTING AND DIAGNOSTICS
POSSIBLE CAUSES
1. If this occurs with the key
switch turned on: Throttle
switch is closed at key start,
the throttle switch must be
opened momentarily before
driving is permitted.
2. If this occurs other than
immediately after the key
switch is turned on: Energy
dump monitoring detects
energy dump circuit is continu-
ously on for more than 30 sec-
onds.
1. Current in brake circuit is
greater than 100 mAmps with
brake energized. Controller
limits drive torque current to
zero in this condition.
Battery pack voltage is below
25%.
Repair and Service Manual
DIAGNOSTIC STEP
1. Turn key switch to 'OFF'.
2. Release throttle, check throttle switch, it
should be open, if closed see ACTION 1.
3. Check resistor control module (DI 2 pin
14), if shorted see ACTION 2.
1. Normally occurs with a panic stop.
Release brake pedal.
2. Check brake switch for closed position, if
open see ACTION 1.
3. Check wiring for open brake circuit, if open
see ACTION 2.
1. Check battery voltage across all 4 batter-
ies, voltage should read 42 VDC MINIMUM.
3. Verify that all battery wires are securely
fastened and have less than 0.1 ohms resis-
tance between wire terminal and battery
post.
3. Verify power resistor ohm reading is
between 0.2 ohms and 0.5 ohms.
4. Remove resistor control module connec-
tion to controller B- terminal, if error status
changes see ACTION 3.
B
ACTION (post diagnos-
tics)
1. Replace throttle switch
2. Replace resistor control
module.
3. Replace controller.
1. Replace brake switch.
2. Replace wiring.
3. Replace controller.
1. Fully charge battery
pack
2. Tighten or replace loose
or high resistance power
wire connections.
3. Replace power resistor.
4. Replace resistor control
module.
5. If error continues
replace controller.
