ELECTRICAL SYSTEM AND TESTING:
ELECTRIC VEHICLES
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Slowly push the vehicle a short distance (about 3 feet (1 meter)).
3. You should feel resistance as motor braking is applied. The reverse buzzer will also begin pulsing. If neither of
these conditions are present, test the Motor Speed Sensor.
See Motor Speed Sensor on page 22-30. If the
Motor Speed Sensor is operational, replace the walk away braking relay.

Figure 22-23 CDM
The CDM can be used to retrieve from the onboard computer four important items of information that can be useful in
troubleshooting the IQ Plus vehicle. To access one of these items, the item’s corresponding Function Code must be
selected on the CDM. This is done by pressing the Function Button until the desired function code is displayed in the
window.
See Figure 22-23, Page 22-36 for CDM features. Releasing the button when the desired code is displayed
will display the data. Function codes and corresponding data are as follows:
• F1 – Battery voltage:
This displays the battery pack’s current state of charge. A reading of less than 48 volts indicates that the batteries
need to be charged. If a reading of less than 48 volts is obtained immediately after a charge cycle, there may be
a problem in the charge circuit.
• F2 – Energy units removed since last charge cycle:
If the display reads over 75 (the vehicle battery warning light should be illuminated), the vehicle batteries need
to be recharged before being used again. This data can be used to make sure all vehicles in a fleet receive
equal usage on a short-term basis.
• F3 – Total accumulated energy units removed since initial vehicle start-up:
This information is most useful in making sure that all vehicles in a fleet receive equal usage over long periods
of time.
• F4 – Last charge termination type (0 = no charge history, 1 = incomplete, 2 = DVDT, 4 = normal, 8 = max.
