WARNING: Review Service Precautions. Improper handling could cause activation of the airbag(s) and lead to injuries!

TROUBLE CODE RETRIEVAL
Defect (trouble) codes may only be retrieved from the Supplemental Restraint System (SRS) control module using the BMW MoDiC system, AST 5500 Recall/Reset tool or other BMW diagnostic system compatible tester.

Connect the diagnostic tester to the data link connector and initiate the trouble code recall procedure as per equipment manufacture instructions.

If trouble code(s) are present, refer to the Trouble Code Table for code identification and description. With BMW or BMW Compatible Equipment

Things To Remember
- The diagnostic procedure is not possible if plug X74 is disconnected.

- When elements of the system, such as steering wheel or instrument cluster are removed when the airbag system is in standby mode (as of terminal R), this is also detected by the diagnostic system as a defect and stored in the trouble code memory. Therefore, it is absolutely necessary to clear the airbag trouble code memory after installation of these components.

- The diagnostic program detects which version of the airbag system is installed in the vehicle and automatically assigns the corresponding troubleshooting procedure (MoDiC only).

- The text "data transfer error" which may appear in the last line during troubleshooting can be ignored (appears when battery disconnected). If the text "airbag control unit found" appears on the identification page, this indicates that although the diagnostic program has detected an airbag control unit, the troubleshooting procedure has been allocated incorrectly (MoDiC only).

CAUTION: Performing the diagnostic procedure without sufficient ground connection (by way of screw connection) at the casing of the diagnostic unit can cause damage to the diagnostic unit.
