BOLT 1552225 - Caterpillar

Test Step 1. CHECK FOR POWER AT THE SENSOR
Turn the key start switch and the disconnect switch to the OFF position.
Do not disconnect the harness connector from the sensor.
At the back of the harness connector for the sensor, insert 7X-1710 Multimeter Probes along voltage supply A (wire R800-OR(Orange)) and along return contact B (wire P967-PU(Purple)).
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact A to contact B. Expected Result:The voltage measurement is 8.0 0.5 DCV.Results:
OK - The voltage measurement is 8.0 0.5 DCV. The power supply circuit is correct. Proceed to Test Step 2.
NOT OK - The voltage measurement is not 8.0 0.5 DCV. The power supply circuit is not correct.Repair: There is a problem with the power supply circuit for the sensor. Refer to the complete Electrical System Schematic of the machine. Check all of the connections that are in the power supply circuit and the return circuit. Ensure that all connections are clean, that all connections are secure and that all connections are in good condition. Repair the machine harness or replace the machine harness. STOPTest Step 2. CHECK THE SENSORTurn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the "right steering cylinder" position sensor and disconnect the machine harness connector from the "left steering cylinder" position sensor. Mark the harness connector for the "right steering sensor".
Connect the marked connector for the "right steering sensor" to the connector for the "left steering sensor". Connect the connector that is not marked for the "left steering sensor" to the connector for the "right steering sensor" .
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Observe the status of the active diagnostic code for the right steering sensor. Expected Result:When the harness connectors are switched, the CID 2201 FMI 03 diagnostic code for the "right steering sensor" is not active. A CID 2200 FMI 03 diagnostic code for the "left steering sensor" is now active.Results:
YES - The CID 2201 FMI 03
