Machine ECM (MID 39)
DTC Code Description System Response
2661-3 Cab Air Temperature Control: Voltage Above Normal Sensor will hold last known Value.
2661-4 Cab Air Temperature Control: Voltage Below Normal Sensor will hold last known Value.
2811-3 Cab Blower Speed Control: Voltage Above Normal Sensor will hold last known Value.
2811-4 Cab Blower Speed Control: Voltage Below Normal Sensor will hold last known Value. Possible causes for an FMI 3 diagnostic code are:
The power supply circuit for the sensor is open.
The return circuit is open.
The signal circuit is open or the sensor is disconnected.
The signal circuit is shorted to the sensor power supply.
The sensor has failed.
The sensor was activated in Cat ET when the component is not on the machine.
The ECM has failed. This situation is unlikely.Possible causes for an FMI 4 diagnostic code are:
The signal circuit for the sensor is shorted to ground.
The sensor has failed.
The Machine ECM has failed. A failure of the Machine ECM is unlikely.

Schematic of the active analog sensors
Note: The diagram above is a simplified schematic of the connections for the active analog connections. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of the electrical schematic for the specific machine being serviced for the complete schematic.Diagnostic Trouble Code Procedure
Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. Look for and repair areas that indicate wires are exposed. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing a troubleshooting procedure.

Troubleshooting Test Steps Values Results
1. Identify Active DTC Code Associated With Sensor Circuit
Code present. FMI 3 diagnostic code, proceed to Test Step 2.
FMI 4 diagnostic code, proceed to Test Step 6.
Begin Process For FMI 3 Troubleshooting HERE
2. Check The Supply Voltage at the Sensor
A. Turn key start switch and disconnect switch ON.
B. Disconnect the machine harness from sensor.
C. Refer to the schematic to determine the voltage source for the suspected faulty sensor.
D. Measure voltage between supply and return contacts at the machine harness connector for the sensor.
Voltage is 8V .5V or 24V 0.5 OK - The voltage reading is correct for the suspected faulty sensor.
Proceed to Test Step 4.
NOT OK- The voltage is NOT correct for the circuit.
Repair - If there is an active CID 41 troubleshoot it. If there is not an active CID 41, replace the circuit breaker associated with the sensor.
Proceed to Test Step 7.
3. Check For An Open In The Sensor Circuit
A. The sensor remains disconnected from the machine harness.
B. Turn the key start switch and the disconnect switch OFF.
C. At the harness connector for the sensor, place a jumper wire between the signal contact and frame ground.
D. Disconnect J1 and J2 harness
