B2A33 Code - LED Backlighting Output Circuit Short To Ground
Quick Answer
When the parking lamps are on, the Smart Junction Box (SJB) sends a Pulse Width Modulated (PWM) voltage to the dimmable components. Common causes include Faulty LED Backlighting, LED Backlighting harness is open or shorted, LED Backlighting circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
