FILTER ELEMENT AS-TRANSMISSION 5067044 - Caterpillar

Illustration 1 g01249899
Schematic for the crank without injection
Test Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the OFF position.
Illustration 2 g01249923
Locations of the circuit components for the crank without injection
(1) Crank without injection plugs
(2) J1/P1 ECM connectors
Thoroughly inspect the connector for the crank without injection plugs (1). Also, thoroughly inspect connectors (2). Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Illustration 3 g01249918
Terminal locations at the P1 ECM connector for the crank without injection
(P1-35) Crank without injection input (NC)
(P1-44) Crank without injection input (NO)
Illustration 4 g01250093
Terminal locations at the connectors for the crank without injection
(Terminal A) Return (chassis ground)
(Terminal B) Crank without injection input (NC)
(Terminal C) Crank without injection input (NO)
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the 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 that all connectors, pins, and sockets are completely inserted and coupled. The harness and wiring must be free of corrosion, of abrasion, and of pinch points. All connections and grounds must be tight and free of corrosion. Expected Result:All connectors, pins, and sockets are completely inserted and coupled. The harness and wiring are free of corrosion, of abrasion, and of pinch points. All connections and grounds are tight and free of corrosion.Results:
OK - The harness and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in 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. Check the Status on Cat ET
Check the connector for the crank without injection in order to ensure that the plug for HHH (engine run) is installed.
Connect Cat ET to the service tool connector.
Turn the keyswitch to the ON position.
Observe the status for "Crank w/o Injection" on Cat ET.
Turn the keyswitch to the OFF position.
Remove plug HHH (engine run) and install plug JJJ (crank w/o injection input).
Turn the keyswitch to the ON position.
Observe the status for "Crank w/o Injection" on Cat ET. Turn the keyswitch to the OFF position.Expected Result:The status reads "Off" when plug HHH (engine run) is installed. The status reads "On" when plug JJJ (crank w/o injection input) is installed.Results:
OK - The status of the "Crank w/o Injection" on Cat ET agrees with the results that are stated above.Repair: The feature is working properly. There may be an intermittent problem in a connector or in the wiring harness. If an intermittent problem is suspected, refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct troubleshooting procedures.STOP
Not OK - The status of the "Crank w/o Injection" on Cat ET does not agree with the results that are stated above. The ECM is not detecting the inputs correctly. Proceed to Test Step 3.Test Step 3.
