Reading off programming data

If the VGLA control module needs to be replaced, all data in the old control module must first be read off so that the new control module can be correctly configured. This is carried out with the Volvo Scan Tool (ST) as follows: Select PROGRAMMING and then READ PROG.STAT. The lock and alarm system configuration can now be read off. Read off and note all values. Replace control module according to Replacing main control module , and program in the previously read values. The three PINs must be obtained from the Volvo central car register, using the same procedure as ordering a mechanical key, and programmed into the new control module. If the fault in the control module makes it impossible to read out the programmed value, identification of how the lock and alarm system is equipped and programmed must be carried out visually.
