Details of the c0242 OBD Code
C0242 code indicates a loss of communication with the body control module.
OBD code C0242 means that there is a loss of communication with the body control module.
This code is triggered by the body control module itself when it does not receive expected data from other modules on the communication network.
The signal or system involved in this code is the communication network between various modules in the vehicle, such as the body control module, powertrain control module, and others.
Mechanic’s Tech Notes
Code C0242 indicates a loss of communication with the body control module.
OBDII code C0242 indicates a fault with the Transmission Control Module (TCM) Communication Circuit.
To diagnose, check TCM power and ground using a multimeter.
Use a scan tool to confirm TCM response over the Controller Area Network (CAN) network.
Visually inspect wiring harnesses and connectors for damage, focusing on broken, bent, or corroded pins.
Reflash the TCM if necessary.
This process helps ensure proper communication between the TCM and other vehicle modules.
