Note: The Engine Control Switch (ECS) is mounted within an instrument panel that is located on the right side of the engine. The ECS is locked into the AUTO position with a pin. The pin must be removed in order to perform this test. After performing this test, ensure that the ECS is placed in the AUTO position and that the locking pin has been reinstalled.Test Step 1. Check for Connector Damage.
Disconnect the main power.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test 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 circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring should be free of corrosion, of abrasion or of pinch points.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Attempt to Start the Engine
Turn the circuit breaker for the battery to the ON position.
Connect the Cat ET to the service tool connector.
Turn the ECS to the STOP position.
Observe the "startup mode" parameters on the Cat ET status screen.
Turn the ECS to the START position. Continue monitoring engine parameters as the engine cranks.
The crank cycle will continue for the time that is equal to the cycle crank time that has been programmed or the crank cycle will continue until the engine speed reaches the crank terminate speed.Expected Result:The status screen for the "startup mode" parameter should display "CRANK". The engine cranks.Results:
OK - The "startup mode" parameter on the status screen on the Cat ET displays "CRANK". The engine cranks.Repair: The circuit is working properly. Check for active diagnostic codes. Stop.
Not OK-Engine Doesn't Crank - The "startup mode" parameter on the status screen on the Cat ET displays "CRANK". The engine will not crank. Proceed to test step 3.
Not OK-Status Screen - The "startup mode" parameter on the status screen on the Cat ET does not display "CRANK".Repair: Perform the diagnostic functional test Troubleshooting, "Engine Control Switch (ECS)". Stop.Test Step 3. Manually Crank the Engine.
Turn the ECS to the STOP position.
Open the electronic instrument panel.
Connect one end of a voltmeter to - Battery terminal. Connect the other end of the voltmeter to wire 304-WH on terminal 2 of
