5. Use a jumper wire with an alligator clip at each end and connect one alligator clip to the negative post
of battery no. 1 and the other alligator clip to the brown/white wire terminal socket that was removed from
the six-pin connector plug.
6. Install the wedgelock in the six-pin connector housing and reconnect the six-pin connector plug. Place
the Tow/Run switch in the RUN position and the battery light should illuminate. If the light does not illu-
minate, replace the battery warning light assembly.
COMMUNICATION DISPLAY MODULE (CDM)
The CDM can be used to retrieve from the onboard computer four important items of information that can be
useful in troubleshooting the electric 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 21-13, Page 21-33 for CDM features . Releasing the button
when the desired code is displayed will display the data. Function codes and corresponding data are as fol-
lows:
• 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 batter-
ies 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.
