Ether Control System
Show/hide table
| NOTICE |

|
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only. |
Ether is automatically injected during cranking by the Electronic Control Module (ECM). The ECM automatically injects ether into the air inlet manifolds when the following conditions are met:
- The ether control parameter is programmed to "Enabled".
- The engine rpm is between 0 and 1200 rpm.
- The jacket water coolant temperature or the inlet manifold temperature sensor is below the set point.
The duration of ether injection varies with the coolant temperature.
For troubleshooting, an override is available for the technician to actuate the ether system. By using Caterpillar Electronic Technician (ET), ether injection can be started and stopped.
