Lost Communication with Restraint Control Module ⚠️ | Airbag System Problem | YouTube Video Description

In this video, we explain the Lost Communication with Restraint Control Module (RCM) error in cars 🚗.
This problem is related to the airbag (SRS) system and should never be ignored, as it can prevent airbags from deploying during an accident.

The vehicle’s main control units are unable to communicate with the Restraint Control Module, which manages airbags and seat belt pretensioners.

Common causes:

RCM power or ground issue

CAN / LIN communication wiring fault

Loose or corroded connectors under seats or dashboard

Accident history or internal RCM failure

Low battery voltage


Possible symptoms:

Airbag / SRS warning light ON

Diagnostic trouble codes (DTCs) stored

Airbags may not function properly


Basic checks & solutions:

Scan vehicle with diagnostic tool

Check battery voltage and fuses

Inspect RCM connectors and wiring

Repair CAN communication issues

Replace or reprogram RCM if required


⚠️ Safety Note: Always disconnect the battery before working on airbag-related components.
