(P1-13) Output No. 4
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the relay circuit.
Check the allen head screw for each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Check the harness and wiring for abrasion and for pinch points from the relay to the ECM. 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 connectors appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem with the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. 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. Determine the Configuration of the Engine Shutdown Output
Connect the Caterpillar Electronic Technician (ET) to the service tool connector.
Turn the keyswitch to the ON position.
Use Cat ET to check the configuration parameter for "Engine Shutdown Output". Record the parameter setting.
Verify that the "Engine Shutdown Output" parameter is programmed to reflect the current wiring for the circuit.
Turn the keyswitch to the OFF position. Expected Result:The parameter is programmed to reflect the current wiring for the circuit.Results:
OK - The parameter is programmed to reflect the current wiring for the circuit. The relay for the engine shutdown output is wired correctly. Proceed to Test Step 3.
Not OK - The parameter is not programmed to reflect the current wiring for the circuit.Repair: The parameter is not programmed correctly. Update the customer specified parameter in order to match the correct wiring for the circuit.STOPTest Step 3. Use Cat ET to Check the Relay
Turn the keyswitch to the ON position.
Access the "Engine Shutdown Output Special Test" on Cat ET. The "Engine Shutdown Output Special Test" will enable the "Engine Shutdown Output" when the test is active.
Begin the "Engine Shutdown Output Special Test" and listen for the relay to click. You may need to be near the relay in order to hear the click.
Turn the keyswitch to the OFF position. Expected Result:An audible click is heard at the relay when the test is activated.Results:
OK - An audible click is heard at the relay.Repair: The relay appears to be operating correctly at this time. There may be an intermittent electrical problem in the harness or in a connector. If an intermittent problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect" for information that is related to troubleshooting intermittent electrical problems.STOP
Not OK - An audible click is not heard at the relay when the test is activated. Proceed to Test Step 4.Test Step 4. Check for Proper Operation of the ECM
Disconnect the J1/P1 ECM connector .
Install a 208-0059 Adapter Cable As (70-PIN BREAKOUT) at the J1/P1 ECM connector .
If the "Engine Shutdown Output" is programmed to "J1/P1:10", remove the wire from terminal location P1-10 at the ECM connector. Connect a voltage test lamp between terminal 10 (output No. 2) and terminal 65 (−Battery) of the breakout T.
If the "Engine Shutdown Output" is programmed to "J1/P1:12", remove the wire from terminal location P1-12 at the ECM connector. Connect a voltage test lamp between terminal 12 (output No. 3) and terminal 65 (−Battery) of the breakout T.
If the "Engine Shutdown Output" is programmed to "J1/P1:13", remove the wire from terminal location P1-13 at the ECM connector. Connect a voltage test lamp between terminal 13 (output No. 4) and terminal 65 (−Battery) of the breakout T.
Turn the keyswitch to the ON position.
Access the appropriate "Engine Shutdown Output Special Test" on Cat ET.
Activate the "Engine Shutdown Output Special Test" while you watch the voltage test lamp. For correct operation of the ECM, the test lamp will illuminate during the test. Deactivate the test and observe the voltage test lamp again. The test lamp will turn off as the test deactivates.
Stop the special test. Note: A multimeter can not be used in place of the voltage test lamp when the ECM outputs are being tested.
Turn the keyswitch to the OFF position.
Restore the wiring to the original configuration. Expected Result:The voltage test lamp turns on when the "Engine Shutdown Output Special Test" is active. The voltage test lamp turns off when the "Engine Shutdown Output Special Test" is not active.Results:
OK - The voltage test lamp turns on when the "Engine Shutdown Output Special Test" is active. The voltage test lamp turns off when the "Engine Shutdown Output Special Test" is not active.Repair: The ECM is OK. The problem is in the wiring harness or in a connector between the ECM connector and the relay. Check for a problem with the relay. Repair the wiring harness and/or replace the wiring harness. Send the vehicle to the OEM dealer for repair, if necessary. Verify that the original condition is resolved.STOP
Not OK - The voltage test lamp did not turn on according to the above requirements.Repair: There is a problem with the ECM. Perform the following procedure:
Temporarily connect a test ECM. Refer to Troubleshooting, "Replacing the ECM".
Recheck the circuit in order to ensure that the original problem has been resolved. If the problem is resolved with the test ECM, install the suspect ECM. If the problem returns with the suspect ECM, replace the ECM. Verify that the problem is resolved.If the problem is not resolved with the test ECM, install the original ECM. There is a problem in the wiring.Send the vehicle to the OEM dealer for repair, if necessary.STOP
