2.63 Controller Check—IntelliDrive® Transport System
Chapter 2: Troubleshooting Procedures
2.63 Controller Check—IntelliDrive® Transport System
1. Remove the drive box from the bed.
2. Place the drive box on wooden supports so the drive belt will not touch the
ground when it deploys.
3. Connect the bed cables running into the box.
4. Locate DS 1 on the PACM board.
5. Observe the following on DS 1:
• LED DS 1 is off—The controller is either not powered or is not getting a
KS 1 signal (which should be present if the wheel is deployed).
• LED DS 1 is on and steady—Controller is operating correctly.
• LED DS 1flashing—Record the flash pattern. Use the brake and steer pedal
to cycle the drive belt. Observe the LED DS 1. If LED DS 1 is still
flashing, refer to table 2-6 on page 2-75 for error codes.

Flash Code Description Possible Cause
¤ ¤
Thermal Cutback 1) Make sure the bed temperature is within the
normal operating range 58°F to 103°F (15-40
degrees C).
2) Check for mechanical binding or item stuck in
drive train or belt.
3) Replace Controller.
¤ ¤¤
Throttle Fault 1 1) Make sure the controller is getting approxi­
mately 2.5 V input when the handles are neutral,
4.0 V when they are pushed forward, and 1.0 V
when they are pulled back. If these voltages are not
present, the problem is in either the Junction board,
the cable from controller to PACM board, or the
cable from PACM to Junction.
2) If voltages are OK, replace controller.
¤ ¤¤¤
SPD Limit Pot Fault 1) Check the cable from controller to PAC board
and cable from PACM to Junction board.
2) Replace Controller.
3) Replace Junction board.
¤ ¤¤¤¤
Low Battery Voltage 1) Make sure the controller is getting correct bat­
tery voltage.
2) Replace Controller.
