Terminal locations for ECM
Thoroughly inspect ECM vehicle harness connector J1/P1 and the firewall bulkhead connector.Refer to Troubleshooting, " Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the switches.Refer to Illustration 2.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the harness and wiring for abrasion and pinch points from the sensor to the ECM.Expected Result:All connectors, pins, and sockets should be completely coupled and/or inserted and the harness and wiring should be free of corrosion, abrasion, or pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following 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 Switch Status on ET

Switch Position or Pedal Position     Switch Status     Circuit    
The Service Brake is Depressed.     ON     Shorted    
The Service Brake is Released.     OFF     Open    
Access the status screen on the Caterpillar Electronic Technician (ET).
Turn the ignition key switch to the ON position.
Start the engine or ensure that the air system is charged if the vehicle is equipped with air brakes.
Depress the Service Brake while the status of both brake switches is being observed on ET.
Release the service brake while the status of both brake switches is being observed on ET.Note: If the Service Brake Pedal Position (Switch 2) status indicates "Not Installed", check the programming of the "Transmission Style" parameter. The "Transmission Style" must be programmed to Automatic Option 2 or Automatic Option 3 if a second switch is used.Expected Result:The switch status changes per the information in table 2Results:
OK - The switch is operating normally.Repair: Perform the following diagnostic procedure:Troubleshooting, "Service Brake Pedal Position (Switch 1) Circuit - Test".STOP
Not OK - The ECM is not reading the switch status change. Proceed to Test Step 3.Test Step 3. Check the Switch Circuit of the ECM

Turn the ignition key switch to the OFF position.
Fabricate a jumper wire 100 mm (4 inch) long. Crimp a Deutsch pin to both ends of the wire.
Disconnect vehicle harness connector P1 from the ECM.
Connect a 70-Termial Breakout T to ECM connector J1 and connect P1 to the breakout T.
Install the jumper wire into terminal 52 (unswitched +Battery) of the breakout T. Connect the other end of the jumper wire to (terminal 64) which is the Service Brake Pedal Position (Switch 2) of the breakout T.
Turn the ignition key switch to the ON position.
Connect ET to the cab data link connector.
Access the status screen on ET.
