Technical specifications
Special features
. The letter ” S ” after 4 means that the system has electronic accelerator;
. It is considered a hybrid plant, because it has the injection and immobilizer maps on the processor.
. Injection and immobilizer maps can only be accessed with ST10 programmer, and through Boot.
Common defects
. Failure in the DC motor drive, causing failure in the acceleration.
. Processor software failure.Many power plants may malfunction due to defect in the processor software (oscillation of idling, acceleration failure, etc.). exchange the software for another (tele-loading). Ignition drive – VB 025 MSP Between point 9 of the component and the processor, there is a current limiting resistor of 1Kohms.
Lambda probe heating control – VDN 7N V04 This component controls the negative, by PWM, varying the applied voltage.
Mult Drive L9131 – 36 Pins Controls 10 components of this ECU.
Butterfly motor control drive – TLE 6209 R Controls the opening and closing of the throttle acceleration, by PWM.
Pins 1 – 10 – 11 – 20 (Ground) are connected to the metal at the bottom of the component, where it should be soldered to the circuit board.This ensures that the component don’t overheat.
Detonation interface – AA205AC1 – H992N0430 – ST – 20 Pins
The detonation circuit has no capacitors at the input, only 2Kohms series resistors.
