Programming Control Module

WARNING: This page is about a different car, the 1996 Mercedes-Benz C280 and 1996 Mercedes-Benz C220. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Hand-Held Tester (HHT) (6511 0001 99) is necessary to set control module parameters.

CAUTION: When programming control module, avoid interrupting control module voltage supply. Damage to control module may result. Control module parameters can only be set once. DO NOT connect Hand-Held Tester (6511 0001 99) to Data Link Connector (DLC) with ignition on. Damage to HHT may result.

After replacing control module, when ignition is turned on, SRS warning light will continuously blink, indicating that control module needs to be programmed. All replacement control modules are programmed to recognize passenger-side air bag module as installed (YES), and occupied seat recognition as not installed (NO). Occupied seat recognition will be deleted in the future. Turn ignition off. Connect Hand-Held Tester (HHT) (6511 0001 99) to DLC. DLC is located in right rear corner of engine compartment. It may be necessary to use Adapter (140 589 1463 00) to connect HHT to DLC. Using HHT, follow HHT prompts to program replacement control module. Currently all control modules are programmed with the same parameters. After control module parameters are set, SRS warning light will go out.
