Airbag lyset lyser

[Petimo]

Airbag lyset lyser på min passat 3b 98mod. og når jeg kjører diagnose på den så får jeg opp koden 01221  når jeg søkker på nettet så er det vist airbag sensor til førersetet som er defekt.

Er det noen som vet noe om dette og er det den lille boksen som ligger bak bjelken omtrent under setet? den som på bildet er merket som nr.1 som da må byttes?

Du skal få opp mer enn bare koden 01221, er det bak feilkoden som teller.

Special Notes

• The US Market (9M) Jetta has a common Airbag Control Module replacement conflict with the existing Crash Sensors. This is mentioned in TSB # 69-08-04 with the following example:
  • When control module 1C0-909-605-F-004 (coded to 12340) is replaced with 1C0-909-605-F-01E the original Crash Sensors are not compatible. The new module will refuse coding if DTCs 01221, 01222, 01738, or 1739 are stored. This is also noted here: Airbag Coding

The Crash Sensors can be checked by using the control module identification and the measuring blocks.

Address 15: Airbags   Controller: 1T0 909 605    Component: 05 AIRBAG VW62 0506 2112   Coding: 0012341

The 0506 in this example stands for the required Crash Sensor ID, the first 2 digits (05) apply for the front crash sensors, while the second 2 digits (06) apply for the rear crash sensors. The ID of the currently installed Crash Sensors can be determined by checking Measuring Value Block (MVB) 009.
