TUBE AS-FUEL 4858987 - Caterpillar

If there is an active engine shutdown, the ether injection system is disabled .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 the ECM parameters
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.During the following procedure, refer to the electrical schematic for the application.Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Remove the electrical power from the ECM.
B. Thoroughly inspect the ECM connector J1/P1. Inspect all of the other connectors for the circuit. Refer to the diagnostic functional test Troubleshooting, "Electrical Connectors - Inspect".
C. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
D. Check the ECM connector (allen head screw) for the correct torque of 6 N m (53 lb in).
E. Check the harness and the wiring for abrasion and for pinch points.
Loose connection or damaged wire
Result: The harness and wiring are OK.
