The harness and wiring are free of corrosion, of abrasion, and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.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 2. Check for Active Diagnostic Codes for the Start Enable Relay
Connect Cat ET to the service tool connector.
Turn the breaker for the ECM to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check the starting system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Turn the start/run/stop switch to the START position.
Monitor the active diagnostic code screen on Cat ET. Check the starting system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Turn the start/run/stop switch to the STOP position. Expected Result:No diagnostic codes are active.Results:
OK - No diagnostic codes are active, but a problem is suspected in the starting system. Proceed to Test Step 6.
Not OK - A -6 diagnostic code is active at this time. Proceed to Test Step 3.
Not OK - A -5 diagnostic code is active at this time. Proceed to Test Step 4.Test Step 3. Create an Open at the Start Enable Relay
Disconnect the wire from terminal 3 on the start enable relay. Ensure that the wire is isolated from engine ground and other sources of electrical power.
Monitor the active diagnostic code screen on Cat ET. Check the starting system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Turn the start/run/stop switch to the START position.
Monitor the active diagnostic code screen on Cat ET. Check the starting system for an active diagnostic code. Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Turn the start/run/stop switch to the STOP position. Expected Result:A -5 diagnostic code is now active for the start enable relay.Results:
OK - A -6 diagnostic code was active before disconnecting the wires. A -5 diagnostic code became active after disconnecting the wires. The harness and the ECM are OK. The problem may be in the start enable relay.Repair: Temporarily connect a new start enable relay, but do not install the new start enable relay. Verify that there are no active diagnostic codes for the start enable relay. If there are no active diagnostic codes for the start enable relay, permanently install the new start enable relay. Clear any logged diagnostic codes.STOP
Not OK - A -6 diagnostic code remains active. There is a short between the start enable relay and the ECM. Leave the wires for the start enable relay disconnected. Proceed to Test Step 5.Test Step 4. Create a Short at the Connector for the Start Enable
