Electronic diesel system (EDS), engines 602.962 and 603.970

The EDS control unit processes the following functions:
1. Electronic idle speed control (ELR),
2. Exhaust gas recirculation (EGR),
3. Intake manifold air pressure control (P2-control), engine 602.962 only,
4. System diagnostics.

The EDS control unit processes the input signals and supplies a milliamp current to the vacuum transducers and to the electromagnetic actuator for idle speed control on the injection pump. Through additional terminals leading to a test connector, the entire system can be tested via blink code signals.
