Description

(1) engine ECU CONTINENTAL SID807

"a" 53-way black connector (CH)

"b" 53-way brown (CMI) connector

"c" 48-way grey connector (CME)

Make: Continental

Role

The engine management ECU manages the entire injection system

The engine management ECU software incorporates

  • Check functionalities of injection and pollution control
  • Driving improvement strategies
  • The immobiliser function ADC2R
  • Emergency strategies
  • Fan unit and warning lamp operating management (*)
  • The diagnostic with memorisation of failures
  • The cruise control and speed limiter function (*)

Note(*) according to specification

The engine management ECU electrically controls the following components

  • Diesel injectors
  • Fuel flow regulator
  • Variable geometry turbocharger control solenoid valve
  • Exhaust heat saver electrovalve (RTE) (*)
  • Pre and post-heating control unit
  • Diesel fuel heater
  • "Blow-by" heaters (*)
  • Exhaust gas recycling valve

Note(*) according to specification

The atmospheric pressure sensor cannot be separated from the engine ECU

The engine management ECU has 2 power stages which are able to supply the very high control current necessary for the operation of the diesel injectors
