Power Off: The controller will turn its power off when the ignition voltage: < 6.2
V DC. The controller prepares for entry into Power Down mode. The
preparation involves storing important information into EEPROM.
Reset: During reset, all outputs shall be set to a predefined state. The
controller shall monitor itself for proper operation and enter reset should any
internal errors be detected. The controller shall then restart normal operations
after the computer has properly reset
Over Voltage: the controller will survive no permanent damage if the ignition
voltage do not exceed 26V for more than 1 minute
Reverse Voltage: The controller will survive with no permanent damage: Battery
and/or Ignition voltage < -13V DC for 1 minute
3.6.2.1 .6 Temperature Requirements
Storage: The controller shall suffer no damage as a result of being stored at
temperatures of -40 C or +105 C continuously for 168 hours. If the storage temperature is not as
extremely high as +105 C or as extremely low as -40 C, the ECU could be stored for longer time
without damage.
Operating: The controller shall operate in the ambient temperature from -20 C to +85 C.
3.6.2.1 .7 Maintenance service and Repair
ECU is a non-serviceable part. Once there are problems, it’s important to first
determine if the problem is caused by software/calibration. If it is caused by
software/calibration, please refer to software/calibration reflashing procedure. In the event of ECU
hardware failure or malfunction (during warranty period only) the ECU should be sent back to the vehicle
manufacturer giving complete details of the ECU Part No, Serial number, Vehicle Model & Make,
manufacturing Date, Total kms run on the vehicle, Location of use, Vehicle No, Date of return.
3.6.2.2 INJECTOR
3.6.2.2.1 Appearance
The figure below shows the standard Multec 3 Fuel Injector appearance
3.6.2.2.2 Sealrings
Seal rings for injectors (refer to Figure 12) are made to withstand temperatures
ranging from -40
℃
to 150
℃
(-40 to 302
℉
) without leakage or seeping. They must also be resistant to
varying amounts of fuel additives to fuel (i.e., ethanol, etc.). The following are currently available seal
rings designs. Please contact a Delphi representative if the specific sealing requirements are not met by
these designs:
