CAP AS-TRACK ROLLER 9W7267 - Caterpillar

System Operation Description:Use this procedure in order to troubleshoot the ether system or use this procedure if any one of the diagnostic codes in Table 1 is active or easily repeated.
Table 1
Diagnostic Codes Table    
Code    Conditions which Generate this Code    System Response    
545-5 Ether Start Relay open/short to +batt     The Electronic Control Module (ECM) detects an open circuit and/or a short to the +Battery at the output to the ether start relay.     The code is logged.
Ether injection is disabled.    
545-6 Ether Start Relay short to ground     The ECM detects a short circuit to ground at the output to the ether start relay.
The ECM has been powered for at least two seconds.    The ether injection system will improve cold weather starting of the engine. The ECM controls the ether injection system. The ECM energizes the ether solenoid in a continuous flow for a predetermined amount of time that is based on the coolant temperature. The ether injection system is disabled if there is an active engine shutdown.The ether injection system can also be operated in manual mode. The ether system is switched into manual mode whenever the starting aid switch is depressed.A test on Caterpillar Electronic Technician (ET) allows the technician to activate the ether system for a ten second period. The test is functional when the engine speed is 0 rpm. The test is accessed by selecting the following menus on Cat ET:
"Diagnostics"
"Diagnostic Tests"
"Override Parameters"

Location of ECM connectorsTest Step 1. Inspect the Electrical Connectors and Wiring
Turn the main disconnect switch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test 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 circuit.
Check the ECM connector (allen head screw) for the proper torque. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the customer connector (allen head screw) for the proper torque. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect" for details.
Check the harness and the wiring for abrasion and for pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiringare free of corrosion, of abrasion and of pinch points.Results:
OK - The connectors and wiring are OK. Proceed to Test Step 2.
Not OK - The connectors and/or wiring are not OK.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check for Active Diagnostic Codes
Connect Caterpillar Electronic Technician (ET) to the service tool connector.
Turn the main disconnect switch to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check the ether system for an active diagnostic code.Note: Wait at least 30 seconds in
