Schematic of connector for breakout T (Terminal 5) AP sensor/switch sensor common (Terminal 35) Cruise control set (Terminal 44) Cruise control resume
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.
Remove the wire P1-35 (cruise control set) from the P1 ECM connector.
Remove the wire P1-44 (cruise control resume) from the P1 ECM connector.
Install a 140-2266 Cable As (70-PIN BREAKOUT) to the ECM vehicle harness connector J1/P1.
Verify that Cat ET is connected to the data link connector.
Turn the ignition key switch to the ON position, while the engine is off.
Access the status of the cruise control set/resume switch on Cat ET.
While the switch status is being observed on Cat ET, install the jumper into the breakout T in order to connect P1-35 (cruise control set) to P1-5 (AP sensor/switch sensor common). Also, while the switch status is being observed on Cat ET remove the jumper from the breakout T in order to disconnect P1-35 (cruise control set) from P1-5 (AP sensor/switch sensor common).
While the switch status is being observed on Cat ET, install the jumper into the breakout T. This connects P1-44 (cruise control resume) to P1-5 (AP sensor/switch sensor common). Also, while the switch status is being observed on Cat ET, remove the jumper from the breakout T. This will disconnect P1-44 (cruise control resume) from P1-5 (AP sensor/switch sensor common).Refer to Illustration 6.
Turn the key switch to the OFF position.
Reconnect all wires to the original configuration.Expected Result:The switch status of the cruise control set/resume switch on Cat ET behaves in the following manner:
The switch status of the cruise control set/resume switch changes from "OFF" to set switch "ON" when the jumper is connected from P1-35 (cruise control set) to P1-5 (AP sensor/switch sensor common).
The switch status of the cruise control set/resume switch is "OFF" when the jumper is removed.
The switch status of the cruise control set/resume switch changes from "OFF" to resume switch "ON" when the jumper is connected from P1-44 (Cruise control resume) to P1-5 (AP sensor/switch sensor common).Results:
OK - The input for the set switch and the input for the resume switch of the ECM are functioning correctly. The problem is in the switches of the vehicle or the problem is in the wiring of the vehicle.Repair: Inspect the wiring. Select one of the following options:
Repair the wiring or replace the wiring.
Send the vehicle to the OEM dealer for repair.Verify that the repair eliminates the problem.STOP
Not OK - The ECM is not reading the switch status change.Repair: Perform the following diagnostic procedure:
Temporarily connect a test ECM.
Ensure that the "PTO Configuration" of the test ECM matches the "PTO Configuration" of the suspect ECM.
Recheck the system for active diagnostic codes.
Repeat the test step.
If the problem is resolved with the test ECM, reconnect the suspect ECM.
If the problem returns with the suspect ECM, replace the ECM.
Verify that the repair eliminates the problem.STOPTest Step
