Details of the c1984 OBD Code
Code C1984 indicates a fault in the rear seat belt release switch circuit.
OBD code C1984 indicates a fault with the brake pedal switch circuit.
This code is triggered by the Body Control Module (BCM) when it detects an issue with the brake pedal switch signal.
The brake pedal switch is a critical component that informs the BCM when the brake pedal is pressed, allowing the vehicle to activate brake lights and control various safety systems.
When the BCM receives an abnormal signal or no signal from the brake pedal switch, it will set code C1984 to indicate a problem with the brake pedal switch circuit.
Mechanic’s Tech Notes
Code C1984 indicates a fault in the rear wiper motor circuit on the vehicle.
OBDII code C1984 typically indicates a problem with the transmission control module (TCM).
To diagnose this, start by checking the TCM’s power and ground using a multimeter.
Next, use a scan tool to confirm if the TCM communicates over the Controller Area Network (CAN) network.
If the TCM does not respond, reprogramming or reflashing it may be necessary.
