service tool. Click

the “Clear” button located on the “Read / Clear Fault Codes”
screen. Using ignition power only, power off the vehicle
for at least 15 seconds. Next start the engine and run it at
idle for at least 15 seconds.

of roadway, engage the cruise control to verify proper
operation.

If the error returns, call Bendix at 1-800-AIR-BRAKE for

4.5 TROUBLESHOOTING DIAGNOSTIC
TROUBLE CODES: POWER SUPPLY

IGNITION VOLTAGE TOO LOW

Measure the ignition voltage under load. Ensure that the
ignition voltage is greater than 10 VDC (volts DC). Check
the vehicle battery and associated components. Inspect
for damaged wiring, damaged or corroded connectors and
loose connections. Check the condition of the fuse.

IGNITION VOLTAGE TOO HIGH

Measure the ignition voltage. Ensure that ignition voltage
is not greater than 16 VDC. Check the vehicle battery
and associated components. Inspect for damaged wiring,
damaged or corroded connectors and loose connections.

POWER SUPPLY TESTS

1. Take all measurements at the radar sensor harness

connector.

2. Place a load (e.g. 1157 stop lamp) across the supply

voltage and ground connection. Measure the voltage
with the load. The supply voltage on pin 8 to ground
should measure between 10 to 16 VDC (volts DC).

3. Check for damaged wiring, damaged or corroded

connectors and loose connections.

4. Check the condition of vehicle battery and associated

components. Ensure the connection to ground is
secure and tight.

5. Using the procedures described by the vehicle

manufacturer, check the alternator output for excessive
noise.
