Typical example
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 CB-8 to the OFF position.
Thoroughly inspect the ECM connector J1/P1. 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:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The wiring and connectors are okay. Proceed to test step 2.
Not OK - The wiring and connectors are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Check the Ether Canister.
Remove the ether canister from the ether solenoid. Determine if the canister contains any ether. Ether can not be injected if the canister is empty.Expected Result:The ether canister should not be empty.Results:
OK - The ether canister is not empty. Proceed to test step 3.
Not OK - The ether canister is empty.Repair: Replace the empty ether canister with a new ether canister. Verify that the problem is no longer present. Stop.Test Step 3. Check for Diagnostics on the Caterpillar Electronic Technician (ET).
The ether canister must be removed prior to activating this test.
Start the Cat ET.
Turn the circuit breaker CB-8 to the ON position.
Determine if a CID-FMI 545-05 or 545-06 diagnostic code is active or logged.
Toggle the ether switch. Observe the parameter for the ether switch on the Cat ET.Expected Result:The parameter for the ether switch should display "ON" while the ether switch is toggled. The parameter for the ether switch should display "OFF" when the ether switch is released.Results:
OK - Active Code - The parameter for the ether switch displays "ON" while the ether switch is toggled. The parameter for the ether switch displays "OFF" when the ether switch is released. Active Diagnostics are displayed. Proceed to test step 4.
OK - Logged Code - The parameter for the ether switch displays "ON" while the ether switch is toggled. The parameter for the ether switch displays "OFF" when the ether switch is released. Logged Diagnostics are displayed. Check for an intermittent short or for an open in the wiring or in the connectors.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Verify that the system is operating correctly. Replace the ether canister on the ether solenoid. Stop.
Not OK - The parameter for the ether switch does not display "ON" while the ether switch is toggled. The parameter for the ether switch does not display "OFF" when the ether switch is released. No active codes or logged codes are present. The ether switch is not functioning correctly. Proceed to test step 8.Test Step 4. Check the Output Voltage from the Ether Relay.
Turn the circuit breaker CB-8 to the OFF position.
The ether canister must be removed prior to activating this test.
Remove the ether canister from the ether solenoid.
Remove wire 150-WH from terminal 30 on the ether relay.
Turn the circuit breaker CB-8 to the ON position.
Select Diagnostic Tests from the Cat ET menu.
Select the "Override Parameters" on the Cat ET.
Activate the "Ether Injection" override.
Measure the voltage between terminal 30 on the ether relay and the - Battery terminal.
Disable the "Ether Injection" override.
Turn the circuit breaker CB-8 to the OFF position.Expected Result:The voltage should be 24 3 VDC.Results:
OK - The voltage is 24 3 VDC. The ether injection system is working properly.Repair: Check the wiring to the solenoid from the ether relay. Check the operation of the ether solenoid. Stop.
Not OK - The voltage is not 24 3 VDC. The supply voltage is not present at the normally open contacts of the ether relay. Proceed to test step 5.Test Step 5. Check the Voltage to the Ether Relay.
Turn the circuit breaker CB-8 to the OFF position.Show/hide
