ETHER INJECTION SYSTEM TEST
WARN I N G
Breathing ether vapors or repeated contact of ether with skin can cause personal injury. Personal injury
may occur from failure to adhere to following procedures:
Use ether only in well ventilated areas.
Do not smoke while chan ing ether cylinders.
Use ether with care to avoid fires.
Do not store replacement ether cylinders inliving areas or in operator's compartment.
Do not store ether cylinders in direct sunight or at temperatures above 120°F (49°C).
Discard cylinders in asafe place. Do not puncture or burn cylinders.
To avoid possible injury to personnel, be sure brakes are applied and all controls are in Hold or Neutral
when starting engine.
N OT E
Use this procedure to troubleshoot any suspect pr blems with electrical circuit for ether injection
This procedure covers folowing diagnostic codes:
a. 2417-05 Ether Injection Control Solenoid current high
b. 2417-06 Ether Injection Control Solenoid current low
Ether injection system improves cod weather starting of engine. ECM controls ether injection
Ether injection system is disabled ifthere is an active engine shutdown.
A test on ET allows technician to activate eth r system. Test is functional when engine speed is
zero rpm. Access test via Override Parameters screen on ET.
Inspect electrical connectors and wiring. Refer to Electrical Connector Inspection (WP 0022 00).
Place battery disconnect switch in OFF position (TM 5-3805-291-10).
Thoroughly inspect harness side and ECM side of connectors for ether solenoid. Refer to Electrical Connector
Perform 10 lb (45 N) pull test on each wire in ECM connectors associated with ECM power supply.
Check J2/P2 ECM connector (socket-head screw) for proper torque of 60 lb-in. (7 Nm).
Check J1/P1 ECM connector (socket-head screw) for proper torque of 55 lb-in. (6 Nm).
Check harness and wiring for abrasion and pinch points from sensors back to ECM.
