Table 7, F7: Programming (No.02 Init. ECU) Opel Frontera A

INIT. ECU

Note:

If a new control unit is installed in a vehicle, or a control unit from one vehicle is installed in another vehicle, the control unit must be reprogrammed (TECH 1 function F0:RESET). For this, pay close attention to the following notes, as otherwise the idle speed setting of the engine may be modified to beyond the permitted limits.

In addition, when a control unit is transferred from one vehicle to another, CO adjustment must be carried out (see section 4.6.6 CO adjustment, 20 SE, 22 XE only)

In the future, it will be possible to select other characteristic curves in the control unit for firing angle, fuel injection, idle speed and CO adjustment by selecting a certain code during programming (F1:CHANGE), and thus improve the performance characteristics of the vehicle. This is done in a similar fashion as previously with different coloured octane number plugs.

More detailed information on this will be published in the relevant Technical Information Bulletins TI. Before the publication of the above mentioned Technical Information Bulletins TI, this function should not be used.

If, however, a workshop should experiment with these functions without requisite information, please note that this will lead to changes in the idle speed adjustment.

Engine off

Press key F7 in the system main menu, use the arrow keys to select the desired test and confirm with YES. Follow the instructions in the TECH 1 display.

At present, the Frontera with the 20 SE or X 20 SE engine is equipped with the following control unit:

INIT. - CODING

FO: RESET

F1: CHANGE

Note that, among other adjustments, this resets the idle speed to its basic values. Therefore, if the FO: RESET function is used for an already programmed control unit or adjusted engine, then call up the following TECH 1 function and make / check the relevant adjustment: F6:ECU ADJUSTMENT

IDLE SPEED

Before the publication of the above mentioned Technical Information Bulletins TI, this function should not be used.

If, however, a workshop should experiment with these functions without requisite information, please note that this will lead to changes in the idle speed adjustment. Therefore perform the following TECH 1 function:
