Schematic for the air inlet heater
Test Step 1. Inspect the Electrical Connectors and the Wiring
Remove the electrical power from the ECM.
Illustration 2 g01208064
Typical component locations for the air inlet heater
(1) Air inlet heater
(2) Air inlet heater relay
(3) Ground connector for the air inlet heater
(4) J2/P2 connectors
Thoroughly inspect the connector for the air inlet heater and connector (4). Inspect the connections on air inlet heater relay (2) and air inlet heater (1). Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".

(P2-79) Air inlet heater
Perform a 45 N (10 lb) pull test on each of the wires in the connectors that are associated with the circuit.
Check the torque of the allen head screws for the ECM connectors. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and wiring for abrasion and for pinch points from the air inlet heater back to the ECM and from the air inlet heater back to the battery. Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.Results:
OK - The harness and the connectors appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem with the connectors and/or the wiring.Repair: Repair the connectors and/or the wiring. Replace parts, if necessary. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled. Verify that the repair eliminates the problem.STOPTest Step 2. Check for Active Diagnostic Codes
Connect the Caterpillar Electronic Technician (ET) to the service tool connector. Refer to electronic troubleshooting Troubleshooting, "Electronic Service Tools".
Restore the electrical power to the ECM.
Observe the "Active Diagnostic" screen on Cat ET. Wait at least 30 seconds so that any codes may become active. Look for these codes:
617-05
617-06Expected Result:One of the above codes is active.Results:
Active 05 code - A 05 diagnostic code is active. Proceed to Test Step 3.
Active 06 code - A 06 diagnostic code is active. Proceed to Test Step 5.
No active codes - None of the above codes are active. There may be a problem with the high power circuit. Proceed to Test Step 6.Test Step 3. Check for an Open Circuit to the Relay

Small terminals for the typical air inlet heater relay
Disconnect the wires from the small terminals of the air inlet heater relay.
Install a test lamp across the wires.
Start the "Air Inlet Heater Override" on Cat ET and observe the test lamp. Note: Do not leave the "Air Inlet Heater Override" ON. This prevents unnecessary cycling of the air inlet heater and the battery from discharging. The "Air Inlet Heater Override" has a one minute timer that disables the test when the time expires.
Stop the "Air Inlet Heater Override" and restore electrical power to the ECM. Expected Result:The test lamp turned on while the override was active.Results:
OK - The test lamp turned on while the override was active. The open circuit is in the relay.Repair: Replace the air inlet heater relay. Clear any diagnostic codes. Verify that the problem is resolved.STOP
Not OK - The test lamp did not turn on while the override was active. Proceed to Test Step 4.Test Step 4. Check the Wiring Between the ECM and the Relay
Disconnect the J2/P2 connectors. Note: Be sure to wiggle the harness during the following measurements in order to reveal an intermittent condition.
Measure the resistance between terminal P2-5 and terminal 1 on the connector for the air inlet heater.
Measure the resistance between terminal P2-79 and terminal 2 on the connector for the air i
