- lUCAS high pressure pump adjustment device - (0188-H);
- electronic engine immobilizer.
Note: This is a case where locking and unlocking the module is possible. The module must be unlocked before removing the fuel pump.
Perform the module unlocking procedure in the following order:
- open the driver's window;
- close all car doors;
- turn on the ignition without opening the doors;
- wait about 10 seconds;
- turn off the ignition without opening the doors;
Attention! If the doors were opened after the ignition was turned off, wait 15 seconds and start the procedure again.
- disconnect the engine control module or fuel pump module.
Attention! The time provided for removing this element is 10 minutes, after this time, start the procedure again. This procedure allows you to make sure that the module is really not locked and check the fuel pump on the stand (without changing the module).
Check the high-pressure fuel pump on the bench in the following order:
- if the module is not locked, the fuel pump will operate if power is supplied to the solenoid valve connector installed on the pump: wire 1 (+12 V) and wire 4 (ground).
Remove the fuel injection pump in the following order:
- disconnect the negative battery cable;
