Details of the b19a6 OBD Code
B19A6 code indicates an issue with the left side impact sensor circuit.
OBD code B19A6 means Left Rear Side Object Sensor 2 Circuit Short to Ground.
This code is triggered by the Body Control Module (BCM) when it detects a short to ground in the circuit of the left rear side object sensor 2. The left rear side object sensor 2 is part of the vehicle’s parking assist system, which helps the driver detect obstacles while parking.
When a short to ground is detected in this sensor’s circuit, the BCM sets code B19A6 to indicate the issue.
Mechanic’s Tech Notes
This fault code indicates an issue with the left side curtain airbag deployment loop.
OBDII code B19A6 indicates a fault with the transmission control module (TCM) power supply.
To diagnose this issue, use a multimeter to check the TCM power and ground connections for proper voltage and continuity.
Additionally, utilize a scan tool to confirm communication between the TCM and other modules over the Controller Area Network (CAN) network.
If the wiring harness and connectors appear visually intact, consider reprogramming or reflashing the TCM as a potential fix.
Be thorough in inspecting for damaged components, broken or corroded pins in connectors, and ensure proper power supply to the TCM.
