CABLE AS- 4924322 - Caterpillar

0795 FMI 07 service code can only be recorded if the optional secondary steering system is installed. The secondary steering system must be energized in the power train electronic control module (ECM) software via the Caterpillar Electronic Technician (ET) configuration screen. The power train ECM performs this function with the pressure sensor switch inputs, a test switch, and a relay driver. CID 0795 FMI 07 is not an electronic fault. CID 0795 FMI 07 is just an indication that the secondary steering system is not responding as intended.
Check the status of the fault.
If CID 0795 FMI 07 is active, then CID 0795 FMI 07 cannot be inactivated until the secondary steering system is activated and the secondary steering pressure switch indicates pressure in the system.
After the engine is running, press and hold the secondary steering test switch for five to ten seconds in order to see if the CID 0795 FMI 07 service code changes to inactive.Expected Result: The CID 0795 FMI 07 service code does change to inactive while the test switch is depressed.Results:
OK - The CID 0795 FMI 07 service code does change to inactive while the test switch is depressed. Proceed to Step 2.
NOT OK - The CID 0795 FMI 07service code remains active. STOP.
Check for other recorded service codes.
Other recorded service codes may indicate the reason for the improper operation of the secondary steering system.Expected Result: There are NOT any other recorded diagnostic service codes.Results:
OK - There are NOT any other recorded diagnostic service codes. Proceed to Step 3.
NOT OK - There are other recorded diagnostic service codes. Exit this procedure. Perform and correct the other recorded diagnostic service codes. Return to CID 0795 FMI 07 procedure. STOP.
Check the battery voltage.
Check the battery voltage. The secondary steering motor requires a large current. A weak battery may effect the operation of the motor.Expected Result: The battery voltage is correct.Results:
OK - The battery voltage is correct. Proceed to Step 4.
NOT OK - The battery voltage is NOT correct. Correct the cause of the low battery voltage and verify that the battery voltage is correct. If the conditions are not resolved, continue. STOP.
Check the secondary steering test switch.
Check the secondary steering test switch input to the power train ECM. If the switch is failed to ground, then the power train ECM believes that the operator is manually turning on the secondary steering system. If the pressure switch for the secondary steering system is not indicating pressure, then the CID 0795 FMI 07 service code will be active.Expected Result: The secondary steering test switch is correct. Results:
OK - The secondary steering test switch is correct. Proceed to Step 5.
NOT OK - The secondary steering test switch is NOT correct. Repair the harness or the cause of the failed circuit. STOP.
Check the relay circuit.
Check the circuit after the secondary steering relay from the power train ECM. The power train ECM does NOT drive the final relay that turns ON the secondary steering motor. There are wires from this relay
