Ether injection is disabled. The ether injection system will improve cold weather starting of the engine. The engine Electronic Control Module (ECM) controls the ether injection system. The ether injection system is disabled if there is an active engine shutdown.Activation of the ether starting aid is based from a map using the coolant temperature, intake manifold temperature, and atmospheric pressure. Refer to Illustration 1.
Illustration 1 g02445796The following conditions must be met for the ether injection system to be enabled:
Ether injection is set to enabled in Cat® Electronic Technician (ET)
Engine coolant temperature is less than the "Start Aid Selection Temperature - Coolant". Refer to Illustration 1.
Intake manifold temperature is less than the "Start Aid Selection Temperature - IMAT."
Coolant temperature and intake manifold air temperature are within 11° C of each other.

Breathing ether vapors or repeated contact of ether with skin can cause personal injury. Personal injury may occur from failure to adhere to the following procedures.Use ether only in well ventilated areas.Do not smoke while changing ether cylinders.Use ether with care to avoid fires.Do not store replacement ether cylinders in living areas or in the operator's compartment.Do not store ether cylinders in direct sunlight or at temperatures above 49 °C (120 °F).Discard cylinders in a safe place. Do not puncture or burn cylinders.Keep ether cylinders out of the reach of unauthorized personnel.

Troubleshooting Test Steps Values Results
1. Inspect the Electrical Connectors and the Wiring
A. Turn the main disconnect switch to the OFF position.
B. Thoroughly inspect the connectors. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.
C. Perform a 45 N (10 lb) pull test on the connector wires.
D. Check the harness for abrasions and pinch points.
Connectors and Wiring
Result: The connectors and wiring appear to be OK.
Proceed to Test Step 2.
Result: There is a problem with the connectors and/or wiring.
Repair: Repair or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.
Proceed to Test Step 4.
2. Check the Wiring Between the ECM and the Ether Control
The ether canister must be removed prior to performing this procedure.
A. Verify that the keyswitch is in the OFF position.
B. Remove the ether canister.
C. Disconnect the engine harness connector for the ether control.
D. Connect a digital voltmeter across the two terminals on the engine harness connector for ether control.
E. Turn the keyswitch to the ON position.
F. Measure the voltage across the terminals while the keyswitch is turned ON.
10 VDC
Result: The voltage measured 0 VDC.
Repair: There is a problem in an electrical component between the ECM and the harness connector for the ether control. The problem may be inside an electrical connector. Make the necessary repairs.
Proceed to Test Step 3.
Result: The voltage measured greater than 10 VDC.
Repair: The electrical components between the ECM and the harness connector for the ether control are OK.
Proceed to Test Step 3.
3. Measure the Resistance of the Coil Inside the Ether Control
A. Verify that the ether control is not connected to the engine harness.
B. Measure the resistance of the coil inside the ether control.
20 Ohms
Result: The measured resistance was approximately 20 Ohms.
Proceed to Test Step 4.
Result: The measured resistance was not approximately 20 Ohms.
Repair: Replace the ether control.
Proceed to Test Step 4.
