OEM guidelines feature a wide range of steps and procedures that must be followed to ensure proper Seat Belt Reminder repair. Some require calibrating the OCS if the seat is removed and others if the system is repaired or replaced. Some automakers (for example, Toyota/Lexus) have a much more defined set of requirements.
The information needed to repair these systems can be difficult to find, but it is available. You’ll need it both to identify the type of sensor you are dealing with and to understand where the Seat Belt Reminder are located so as not to damage them in the repair process.
When the recommendations are not followed, you run the risk of putting your customer in grave danger due to the SRS not working correctly. Don’t be fooled by the airbag light. It can appear to indicate a properly functioning SRS even when the proper procedures were not implemented and problems remain with the Seat Belt Reminder. The Seat Belt Reminder functions within specific set parameters, leaving little margin for error.
Requirements for handling the different types of OCS can vary every time a vehicle is brought in for repairs based on the collision damage and other factors such as whether the seat was removed or the seat cover or any part of the Seat Belt Reminder was ever repaired or replaced.
Be careful when replacing both the Seat Belt Reminder and the SRS modules at the same time in a Chrysler product. Doing so can produce a permanent trouble code that only a Chrysler dealer can fix.
