Typical circuit
Personal injury or death can result from using ether.Failure to follow these instructions could result in an explosion and/or fire and possible personal injury.When using starting fluid, follow the manufacturer's instructions carefully. Use ether sparingly and spray it only while cranking the engine. Also, do not store starting fluid containers in the cab.
The ether canister must be removed prior to activating this test.
Do not perform this procedure within 15 M (50 ft) of an open flame.
Test Step 1. Check for Connector Damage.
Turn the circuit breaker for the battery to the OFF position.
Turn the keyswitch to the OFF/RESET position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect the terminals at the start aid lamp. Refer to 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:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Verify that the system is operating correctly. Stop.Test Step 2. Check the Start Aid Lamp
Turn the keyswitch to the OFF/RESET position.
Remove the ether canister from the ether solenoid.
Connect the ET to the service tool connector.
Set the start aid switch to the AUTO position.
Turn the keyswitch to the ON position.
Proceed to the diagnostic override screen on the ET and activate the ether override.Note: The ether override will activate one six second ether injection cycle. The ether will be on for 3 seconds and off for 3 seconds.
Observe the start aid lamp.Expected Result:The ether start aid lamp will be off when the ether override is disabled. The ether start aid lamp will be on when the ether override is enabled.Results:
OK - The ether start aid lamp is off when the ether override is disabled. The ether start aid lamp is on when the ether override is enabled.Repair: The start aid lamp circuit is operating correctly. Refer to Troubleshooting, "Inspecting Electrical Connectors" if you have an intermittent problem. Stop.
Not OK - Lamp Off - The ether start aid lamp will be off when the ether override is disabled. The ether start aid lamp stays off when the ether override is enabled. Proceed to test step 3.
Not OK - Lamp On - The ether start aid lamp is not off when the ether override is disabled. The ether start aid lamp will be on when the ether override is enabled. Proceed to test step 5.Test Step 3. Check the Voltage to the Start Aid Lamp.
Turn the keyswitch to the ON
