(1) Laser Receiver Not Connected, Electric Mast Connected (2) Laser Receiver Not Connected, Electric Mast Not ConnectedTest Step 1. VERIFY THAT THE COMPONENT IS COMMUNICATING ON THE CAN NETWORK
Turn the key start switch and the disconnect switch to the "ON" position.
Move the "Power/Setup" Switch on the Display to the "ON" position.
Ensure that the Icons for the Laser Receiver, show that the sensor is connected. Refer to Illustration 1.Expected Result:The Icon for the sensor indicates that the sensor is on and communicating with the display.Results:
YES - The Icon for the sensor indicates that the sensor is on and communicating with the display. Proceed to Test Step 2.
NO - The Icon for the sensor indicates that the sensor is not communicating with the display. Proceed to Test Step 5.Test Step 2. CHECK THE SENSOR DATA
Turn the "Power/Setup" Switch to the "I" position in order to access the "Configuration" menu.
Toggle a "Menu Scroll" Switch in order to highlight the "Diagnostics" option. Press the "OK" button.

Illustration 3 g01379685
Place the key start switch and the disconnect switch in the OFF position.
Take the following measurement at the connector for the Right or Left Hand laser/sonic harness. Measure the resistance between contact C (wire L854-YL) and contact D (wire L855-GN).Expected Result:The resistance measurement is 60 6 ohms.Results:
YES - The resistance measurement is 60 6 ohms. Proceed to Test Step 5.
NO - The resistance measurement is NOT 60 6 ohms. Proceed to Test Step 4.Test Step 4. CHECK THE CAN TERMINATION RESISTORS.
Place the key start switch and the disconnect switch in the OFF position.
Disconnect the 3-pin connector for all four of the termination resistors.
Measure the resistance between contact A (wire L854-YL) and contact B (wire L855-GN) for all four resistors. Note the resistance.Expected Result:The resistance measurement is 120 12 ohms.Results:
YES - The resistance measurement is 120 12 ohms. Reconnect the resistors. Proceed to Test Step 6.
NO - One or all resistance measurements is NOT 120 12 ohms. Repair: Replace the termination resistor(s) that did not measure 120 12 ohms. Proceed to Test Step 6.Test Step 5. CHECK THE POWER CIRCUIT
Turn the Key Start Switch to the "ON" position.
