Eaton Top 2     X         X        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 neutral switch connects to the ECM through connector P1:62. With DEC03 software, the neutral switch can also connect to the ECM through J1939.

Schematic for transmission neutral switchTest Step 1. Determine the Type of Problem
Connect the electronic service tool to the data link connector.
Turn the key switch to the ON position.
If the vehicle will not allow setting a cruise speed, an idle speed or a PTO speed, check the following customer parameters:Cruise Control Parameters
"Low Cruise Control Speed Set Limit"
"High Cruise Control Speed Set Limit"Idle Parameters
"Idle Vehicle Speed Limit"
"Idle RPM Limit"
"Top Engine Limit" (TEL)PTO Parameters
"PTO Configuration"
"PTO Vehicle Speed Limit"
"Transmission Neutral Switch"
Ensure that the vehicle is not experiencing a problem due to one of these parameters. Refer to Troubleshooting, "Customer Specified Parameters" for a description of the parameters, if necessary.
Check the status screen on the electronic service tool that indicates the last cause of a kickout for one of the following modes:
Cruise Kickout
Idle Kickout
PTO KickoutExpected Result:The problem is due to a parameter setting or the problem is due to a normal kickout.Results:
OK - Explain the proper operation of system to the driver.STOP
Not OK - Repair: If a problem is still suspected with the neutral switch circuit perform the following procedure: Proceed to Test Step 2.Test Step 2. Inspect Electrical Connectors and Wiring
Illustration 2 g00705233
Thoroughly inspect the J1/P1 ECM connector, the firewall bulkhead connector and the terminals for the following switches in the connectors:
J1/P1:62 (Neutral Switch)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 3.
Not OK - 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 3. Check the Status of the "Transmission Neutral Switch"
