Technical specifications
Special features
• The immobilizer is on the processor.
• The immobilizer is optional.
Common defects
The 96/97 system came out with a processor defect. When successive
failures occur, the software of the processor blocks the stepper motor, causing
idle oscillation. This failure will only be repaired when the reset procedure
is performed.
Note: Nozzle drive - Commercial - IRF 34.
Drive relay A
Activate side A of the double relay, by pin 4 of the ECU.
Caution: Between pin 4 of the ECU and the relay drive A has a diode.
Micro transistor that drives the A relay drive
Drive Coils ignition
Drive CA 3262 AE - Relay A / C - Relay B - Injection light
This component works similarly to NPN transistors, that is, the input (trip) is made by positive 5 volts and the output is negative.
