7.1. If the voltage reading is correct in steps 6 and 7, replace the reverse buzzer.
7.2. If reading is zero volts, check orange wire continuity and connection at Pin 10 in 23-Pin connector.
7.3. If there is no continuity in the orange wire, or the Pin 10 terminal in the 23-Pin connector is not properly
seated, repair or replace as required.
7.4. If the orange wire continuity and 23-Pin connector are correct and there is no voltage at the orange wire, replace
the controller.
Test Procedure 18–Rebooting Onboard Computer
It is possible the Onboard Computer (OBC) can become “locked up”, causing the OBC solenoid lockout circuit to
malfunction. If this condition is suspected, restart the computer as follows:
1. Place the Tow/Run switch in the TOW position.
2. Disconnect the batteries, negative cable first, as shown (Figure 11-9, Page 11-10).
3. Discharge the controller as instructed in the WARNING on page 11-11.
4. Reconnect the batteries, positive cable first, and tighten terminals to 110 in.lb (12.4 N-m).
5. Place Tow/Run switch in the RUN position.
6. Test the drive vehicle. If the problem has been fixed, the vehicle will function normally. If the problem still
exists, refer to the diagnostic flow charts beginning on page 11-11.
THE 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 PowerDrive 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 func-
tion code is displayed in the window.
See Figure 11-14, Page 11-23 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 bat-
teries 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 (1 = incomplete, 2 = DVDT, 4 = normal, 8 = max. timer):
A
1
,
2
,
4
, or
8
will be displayed.
1
- Indicates the last charge cycle was incomplete and the batteries were not fully charged. Batteries should
be charged again at the earliest opportunity.
2
- Indicates a back-up charge program was employed by the OBC to complete the charge cycle. A DVDT
charge may be displayed the first few times a new set of batteries is charged, and the first time a set of batter-
ies is charged after the batteries have been disconnected and reconnected. A problem may exist if persistent
DVDT readings are obtained.
