The component detection circuit of Daewoo ESPERO igniting system

Both the high voltage wires of *1 and *2 should be checked to make sure that the wire of spark piston is connecting. If sparks come out when EST plug(wire 4) is being pull off, that means the output voltage of signal picking coil is too low to make EST work. If *3 has sparks, that means the problem is in electricity distributor and spark distributor. When the *4 is in normal condition, there should be battery voltage on both terminals c and + of igniting module, and the voltage is tend to be low, that mean there are breaks or resistance value is too high between distributor and igniting coil or switch.

The fault diagnosis circuit of Daewoo-ESPERO fuel pump relay

Published:2011/5/18 22:22:00 Author:Borg | Keyword: fault diagnosis circuit, Daewoo-ESPERO

The fault diagnosis circuit of Daewoo-ESPERO fuel pump relay
When the igniting switch is at the ON gear, computer ECM will start the fuel pump relay and run the pump in the oil box. When the engine starts or runs, if ECM receives the igniting reference pulse signal, the fuel pump will go on to work; if there is no reference pulse signal, then the ECM will shut down the pump in 2 secondsafter the igniting switch is on. It will lead to a long starting time of the engine if the oil pump relay doesn't work, especially when the temperature of the engine is low or the engine oil viscosity is high. (View)
