5.3.5. Open Circuit Test
The open circuit test will apply voltage to the cabling and check for any open circuits.
1. Ensure all the devices are still disconnected from the bus.
2. Reconnect the cables to the Control Module. (C01, Battery, Display)
3. Turn on the system power.
4. Using a voltmeter, measure the voltage of the following pin combinations at each of the sensor
connections.
Pin # Pin # Value
1 3 0.5 to 6 VDC
1 4 0.5 to 6 VDC
1 6 12 ± 3 VDC
2 5 12 ± 3 VDC
5. If an incorrect value is measured, continue by testing at the next connection until the problem cable is
isolated.
