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.
01221 - Crash Sensor Side Airbag; Driver Side (G179): Implausible Signal
Possible Symptoms
- Airbag Warning Light ON
Possible Causes
- Wrong/Incompatible Crash Sensor Side Airbag; Driver Side (G179) installed
- Wiring/Connections between Airbag Control Module (J234) and Crash Sensor Side Airbag; Driver Side (G179) faulty
Possible Solutions
- Check Crash Sensor Side Airbag; Driver Side (G179) Part Number
- Install correct Crash Sensor Side Airbag; Driver Side (G179)
- Check Wiring/Connections between Airbag Control Module (J234) and Crash Sensor Side Airbag; Driver Side (G179)
