Pin locations on ECM connector (P1-5) AP sensor/switch common (P1-46) Input 7 (diagnostic enable)Test Step 1. Check the Electrical Connectors and the Wiring
Thoroughly inspect the J1/P1 ECM connector and the firewall bulkhead connectors. Refer to Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the suspect switch circuit.
Check the ECM connector (allen head screw) for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and the wiring for abrasion and for pinch points from the battery to the ECM. Then, check from the keyswitch to the ECM.Refer to Illustration 2 for terminal locations for the ECM.Expected Result:All connectors are free of corrosion, of abrasion, and of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair the wiring and connectors or replace the wiring or the connectors. Ensure that all of the seals are properly connected. Verify that the repair eliminates the problem.STOPTest Step 2. Use Caterpillar Electronic Technician (ET) to Check the Status of the Diagnostic Enable Switch
Connect Cat ET at the cab data link connector.
Turn the keyswitch to the ON position.
Operate the diagnostic enable switch in the ON and OFF positions.
View the "Input 7" status on the Cat ET status screen.
If the "Input 7" status indicates "None", then the "Input 7" parameter has not been programmed.Expected Result:The "Status Screen" indicates "ON" if the switch is turned on. The "Status Screen" indicates "OFF" if the switch is off.Results:
OK - The switch is operating normally. Continue troubleshooting if the original condition is not resolved.STOP
Not OK - The ECM is not reading the "Switch Status" change. Proceed to Test Step 3.Test Step 3. Check the Switch Circuit for the ECM

Pin locations on breakout T (5) AP sensor/switch common (46) Input 7 (diagnostic enable)
Turn the keyswitch to the OFF position.
Install a breakout T at the J1/P1 ECM connector.
Fabricate a jumper wire 100 mm (4 inch) long. Crimp a Deutsch pin to both ends of the wire.
Insert the jumper wire into terminal 46 Input 7 of the breakout T. Connect the other end of the jumper wire to terminal 5 AP sensor/switch common of the breakout T.
Verify that the keyswitch is in the ON position.
Alternately remove the jumper wire and then insert the jumper wire from terminal 5. At the same time, monitor the "Status Screen" on Cat ET.Expected Result:The "Switch Status" changes to "ON" with the jumper wire in place. The "Switch Status" changes to "OFF" when the jumper wire is removed.Results:
OK - The ECM is functioning properly at this time. Proceed to Test Step 4.
Not OK - The ECM is not functioning properly.Repair: Temporarily connect a test ECM. 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 repair eliminates the problem.STOPTest Step 4. Insert a Jumper Wire at the Switch
Turn the keyswitch to the OFF position.
Reconnect the J1/P1 ECM connector.
Fabricate a jumper wire 100 mm (4 inch) long. Crimp a Deutsch pin to both ends of the wire.
Insert the jumper wire between the two terminals of the diagnostic enable switch.
Turn the keyswitch to the ON position.
Alternately remove the jumper wire and then insert the jumper wire at the switch terminals. At the same time, watch the "Status Screen" on Cat ET.Expected Result:The "Switch Status" changes to "ON" with the jumper wire in place. The "Switch Status" changes to "OFF" when the jumper wire is removed.Results:
OK - Repair: Replace the diagnostic enable switch.Verify that the repair eliminates the problem.STOP
Not OK - There is a problem in the wire harness between the diagnostic enable switch and the ECM. Proceed to Test Step 5.Test Step 5. Insert a Jumper Wire at the Bulkhead Connector
Turn the keyswitch to the OFF position.
Fabricate a jumper wire 100 mm (4 inch) long. Crimp a Deutsch pin to both ends of the wire.
Locate the suspect switch socket in the engine side of the bulkhead connector.
Insert the wire jumper pin between the switch socket and the sensor common connection. Install the jumper wire on the engine side of the bulkhead connector.
Turn the keyswitch to the ON position.
Alternately connect and then disconnect the jumper wire. At the same time, monitor the "Status Screen" on Cat ET.Expected Result:The "Switch Status" changes from "ON" with the jumper wire in place. The "Switch Status" changes to "OFF" when the jumper wire is removed.Results:
OK - The problem is in the vehicle wiring between the ECM connector and the switch. Inspect the vehicle wiring and then repair the vehicle wiring. Otherwise, send the vehicle to the OEM dealer for repair. Verify that the original condition is resolved.STOP
Not OK - The problem is in the vehicle wiring between the bulkhead connector and the ECM. Inspect the vehicle wiring and then repair the vehicle wiring. Otherwise, send the vehicle to the OEM dealer for repair. Verify that the original condition is resolved. STOP
