Exhaust temperature module
The exhaust temperature module is an electronic monitoring system used to monitor exhaust temperatures. The module monitors the following thermocouples:
Thermocouple for the exhaust port of each cylinder
Thermocouple at the inlet of the turbocharger turbineThe module reads each of these temperatures and sends this information via the CAN data link to the ECM and the optional remote control panel.If the ECM cannot communicate with the exhaust temperature module, the ECM activates a diagnostic code related to identify the problem. The most likely cause of the diagnostic code is a problem with an electrical connector or a harness. The next likely cause is a problem with the exhaust temperature module.Terminating resistors must be connected to each end of the CAN data link. The terminating resistors improve the communication signal between the devices. If there is an intermittent diagnostic code for any of the devices connected to the CAN data link, check the terminating resistors. One of the terminating resistors is in the control panel. The other terminating resistor is inside the ECM control box. If the engine is not equipped with a remote panel, the other terminating resistor will be connected at the far end of interconnect harness. Refer to Troubleshooting, "CAN Data Link - Test" for details related to troubleshooting the data link circuit.This troubleshooting procedure may generate additional diagnostic codes. Correct the cause of the original diagnostic code before continuing. You clear the diagnostic codes after the problem is resolved.

Perform a 45 N (10 lb) pull test on each of the wires in the circuit for each of the exhaust temperature sensors.
Check the torque of the allen head screws for each of the ECM connectors. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and the wiring for abrasion and for pinch points from the battery to the ECM control box. Check that the fuses for the circuit are not blown. Expected Result:All of the connectors, pins, and sockets are connected properly. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good repair with proper connections. Proceed to Test Step 2.
Not OK - The components are not in good repair and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary. Ensure that all of the seals are properly installed. Ensure that the connectors are properly engaged. Verify that the repair has eliminated the original problem.STOPTest Step 2.
