Details of the c1616 OBD Code
Code C1616 relates to a problem with the engine control module.
OBD code C1616 means that a circuit malfunction has been detected in the VIN information stored in the ABS control module.
This code is triggered by the ABS control module when it detects an issue with the VIN information circuit.
The VIN information is used by the ABS module to identify the vehicle and ensure proper communication with other modules on the vehicle network.
If the circuit malfunctions, it can lead to communication errors and affect the proper functioning of the ABS system.
Mechanic’s Tech Notes
Code C1616 indicates a problem with the engine control module (ECM) communication circuit.
OBDII code C1616 relates to a problem with the TCM (Transmission Control Module).
To diagnose, check TCM power and ground using a multimeter.
Verify TCM communication over the CAN network with a scan tool.
Visually inspect wiring harnesses and connectors for damage, and check connector pins for issues like corrosion or bending.
Reflashing the TCM might be necessary.
This code often points to communication faults between modules or internal TCM issues.
