FVDI BSI Solution for PIN Code & Recovery

Hi all,
After going through the nightmare of using my FVDI to read a pin code from Johnsons BSI and then causing BSI to go into Boot mode I have come up with this solution for any users with similar issues.

There is 2 ways of retrieving pin code from BSI:

1st is from OBD – this is the operation that is risky 60/40 chance of causing BSI to go into Boot Mode.

2nd is from direct read(BSI not opened up) with BSI removed – this works 100% of the time.

Solution 1: OBD read

 

This operation can only be done WITHOUT vehicle in Economy mode. Run engine for 15 minutes to give charge into battery. Attach battery charger. Disconnect both headlight connectors & remove wiper motor fuse(usually no.12 in engine fuse box). All doors closed & no power consumers on. Use Diagbox to deactivate economy mode in BSI – If option available. Use FVDI to read pin code.

THE REASON BSI GOES INTO BOOT MODE IS BECAUSE ‘ECONOMY MODE’ ACTIVATED DURING THE PIN CODE RETRIEVAL.
I’ve also used same procedure to change kilometres in instrument cluster/BSI and works okay.

Solution 2: Direct read

 

Remove the BSI from vehicle. Attach BSI on bench. Before reading pin the information from BSI can be recorded incase anything goes wrong during procedure. Use Diagbox/PPS to record configuration in BSI – BSI/REPAIR/CONFIGURATION/MANUAL CONFIGURATION then screenshot all of the options in each section. Use Diagbox to deactivate economy mode in BSI – If option available.

Use FVDI to record flash & configuration using “BSI EXCHANGE” – Read BSI only. This flash will now be stored in folder PSA in documents.

You can now use FVDI to read pin.

BSI RECOVERY: Boot mode

If the BSI has went into Boot mode then the existing flash in BSI has been corrupted. Reflash using FVDI with flash recorded in PSA folder.

If you haven’t got a saved flash then you will need to get a good flash for BSI from the helpful people on this site. Once flash has been loaded onto BSI the pin code & configuration will be lost from its memory. Relearn pin code to BSI with DIAGBOX & learn keys – configure BSI if necessary.
