Test Step 1. Check for Connector Damage
Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF/RESET position.
Check connectors and wiring for the following problems: damage, corrosion, abrasion and incorrect attachment.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The connectors and wiring are free of problems. Proceed to test step 2.
Not OK - The connectors and wiringare not free of problems.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. If necessary, replace the ECS. Stop.Test Step 2. Check the Status of the Switch.
Turn the circuit breaker for the battery to the ON position.
Turn the circuit breaker for the Mag Relay of the Starting Motor System to the OFF position.
Activate the emergency stop switch. This will prevent the engine from starting during the following tests.
Turn the ECS to the STOP position.
Connect the Cat ET to the service tool connector.
Observe the parameter for the ignition switch on the Cat ET.Expected Result:The parameter for the ignition switch should read "STOP".Results:
OK - The parameter for the ignition switch displays"STOP". The ECS is functioning correctly. Proceed to test step 3.
Not OK - The status for the ignition switch does not display "STOP". Proceed to test step 4.Test Step 3. Check the Status of the Switch.
Turn the ECS to the START position.
Observe the parameter for the ignition switch on the Cat ET.Expected Result:The parameter for the ignition switch should read "RUN".Results:
OK - The parameter for the ignition switch displays "RUN". The ECS is working correctly. Proceed to test step 5.
Not OK - The status of the Ignition Switch does not display "RUN". Proceed to test step 4.Test Step 4. Install a Jumper Wire.
Turn the ECS to the OFF/RESET position.
Disconnect ECM connector P1. Remove P1-14, P1-8 and P1-29.
Fabricate a jumper wire.
Install the jumper wire at P1. Connect P1-14 and P1-8 to P1-29. Reconnect P1.
Turn the ECS to the STOP position.
Observe the parameter for the ignition switch on the Cat ET.
Turn the ECS to the OFF/RESET position and remove the jumper wire.Expected Result:The parameter for the ignition switch should display "RUN" while the jumper wire is installed. The parameter for the ignition switch should display"STOP" when the jumper wire is removed.Results:
OK - The parameter for the ignition switch displays the proper status. The problem is not with the ECM. Proceed to test step 6.
Not OK - The parameter for the ignition switch does not display the proper status.Repair: Replace the ECM. Perform the diagnostic procedure Troubleshooting, "Replacing the ECM". Stop.Test Step 5. Check the Status of the Switch.
Turn the ECS to BLACK START ENABLE.
Observe the parameters for the ignition switch on the Cat ET.Expected Result:The parameter for the ignition switch should read "BLACK START".Results:
OK - The parameter for the ignition switch displays "BLACK START".Repair: The ECS is working correctly. Stop.
Ignition Switch Not OK - The parameter for the Ignition Switch does not display "BLACK START".Repair: Replace the ECM. Perform the diagnostic procedure Troubleshooting, "Replacing the ECM". Stop.Test Step 6. Check Switches and Wiring.
Turn the ECS to the OFF position.
Disconnect ECM connector J1/P1.
Measure the resistance between the digital return P1-29 and the Start/Run/Stop Input 1 P1-8.
Measure the resistance between the digital return P1-29 and the Start/Run/Stop Input 2 P1-14.
Turn the ECS to the STOP position and repeat the above two measurements.Expected Result:The resistance should be greater than 20,000 Ohm.Results:
OK - The resistance is greater than 20,000 Ohm. Proceed to test step 9.
Not OK - The resistance is less than 20,000 Ohm. There is a short circuit in the ECS.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. If necessary, replace the ECS. Stop.Test Step 7. Check the Switches and Wiring.
Turn the ECS to the AUTO position with the Remote START/STOP Switch in the STOP position.
Measure the resistance between the digital sensor return P1-29 and the Start/Run/Stop Input 1 P1-8.
Measure the resistance between the digital sensor return P1-29 and the Start/Run/Stop Input 2 P1-14.Expected Result:The resistance should be greater than 20,000 Ohms.Results:
OK - The resistance is greater than 20,000 Ohms. The ECS appears to be functioning properly. Proceed to test step 10.
Not OK - The resistance is less than 20,000 Ohms. There is a short circuit in the ECS. Repair: Repair the connectors or wiring and/or replace the connectors or wiring. If necessary, replace the ECS. Stop.Test Step 8. Install a Jumper Wire.
Turn the ECS to the OFF/RESET position.
Disconnect ECM connector P1.
Remove the wires from P2-01 and P1-29.
Fabricate a jumper wire.
Install the jumper wire at P1 and P2. Connect P2-01 to P1-29. Reconnect P1.
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Observe the parameter for the ignition switch on the Cat ET.
Turn the ECS to the OFF/RESET position.
Remove the jumper wire.Expected Result:The parameter for the ignition switch should read "BLACK START" while the jumper wire is installed. The parameter for the ignition switch should read "STOP" when the jumper wire is removed.Results:
OK - The parameter for the ignition switch is displaying the proper status. Repair: The ECS is functioning correctly at this time. Stop.
Not OK - The parameter for the ignition switch does not display the correct status.Repair: Replace the ECM. Perform the diagnostic procedure Troubleshooting, "Replacing the ECM". Stop.Test Step 9. Check Switches and Wiring.
Turn the ECS to the DGCP START ENABLE position.
