Mazda B2031: Left Corner Lamp Output Circuit Failure
OVERVIEWWhat Does The Mazda B2031 Code Mean?
The Smart Junction Box (SJB) sends reference signals to the multifunction switch through circuit (BR/L) (LH turn input) and circuit (BR/W) (RH turn input). When the multifunction switch is switched to the LH or RH TURN positions, the voltage signal is routed to ground. When the SJB detects the multifunction switch in the LH or RH TURN position, the SJB sends voltage to the appropriate turn lamps.
What Are The Potential Causes Of The Mazda B2031 Code?
- Wiring, terminals or connectors
- Multifunction switch
- SJB
