ARRESTOR GP-SPARK 7W5436 - Caterpillar

A Service Brake Pedal Position (Switch 1) is required for all configurations. The Service Brake Pedal Position (Switch 1) connects to the ECM through connector P1:45. The Service Brake Pedal Position (Switch 2) connects to the ECM through Connector P1:64. The Clutch Pedal Position Switch connects to the ECM through Connector P1:22. The Neutral Switch connects to the ECM through Connector P1:62.

Schematic for cruise control switch, service brake pedal position (switch 1) and clutch pedal position switchTest Step 1. Check the Status for the "Service Brake Pedal Position Switch #1"
Connect the electronic service tool to the data link connector.
Turn the key switch to the ON position.
Access the status for the "Service Brake Pedal Position Switch #1" on the electronic service tool.
While the status for the "Service Brake Pedal Position Switch #1" is monitored, depress the brake and release the brake.Expected Result:The status for the "Service Brake Pedal Position Switch #1" is "Off" when the brake is released. The status for the "Service Brake Pedal Position Switch #1" is "On" when the brake is depressed.Results:
OK - The service brake pedal position (Switch 1) is working correctly.STOP
Not OK - The service brake pedal position (Switch 1) is not working correctly. Proceed to Test Step 2.Test Step 2. Determine the Configuration of the Switch
Determine if the wiring for the service brake pedal position (Switch 1) is wired directly to the ECM or through the J1939 data link.
Verify that the "Service Brake Pedal Position Switch #1" parameter is programmed to reflect the proper wiring.Expected Result:The service brake pedal position (Switch 1) is wired directly to the ECM.Results:
OK - The service brake pedal position (Switch 1) is wired directly to the ECM.Repair: Verify that the "Service Brake Pedal Position Switch #1" parameter is programmed to "J1/P1:45". Proceed to Test Step 3.
Not OK - The service brake pedal position (Switch 1) is wired through the J1939 data link.Repair: Verify that the "Service Brake Pedal Position Switch #1" parameter is programmed to "J1939 - Body Controller", "J1939 - Cab Controller", or "J1939 - Instrument Cluster".Refer to Troubleshooting, "Powertrain Data Link Circuit - Test".STOPTest Step 3. Inspect Electrical Connectors And Wiring
Illustration 2 g00702676
Thoroughly inspect the J1/P1 ECM connector, the firewall bulkhead connector and the terminals for the following switches in the connectors:
J1/P1:5 (AP Sensor/Switch Sensor Common)
J1/P1:45 (Service Brake Pedal Position (Switch 1))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 4.
Not OK - Repair: Perform the following repair:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure
