I've studied the fault codes of the Great Wall Haval H2. B150104 usually indicates an issue with the Body Control Module (BCM), which may specifically involve lighting circuits, sensors, or internal component failures. This code is recorded when the vehicle's computer detects abnormal signals or unstable current. Common causes include short circuits in wiring, loose connectors, module damage, or blown fuses. When I was tinkering with my old car, I encountered similar problems. First, check if the headlight fuse is intact, then inspect the wiring harness connectors in the engine compartment for corrosion. If simple fixes don't work, it's best to use an OBD scanner to read detailed data to avoid blindly replacing parts and wasting money. Don't take this situation lightly—safety first. It's more reliable to have a professional repair shop conduct a thorough inspection.
I've found that the fault code B150104 in the Haval H2 often indicates an abnormality in the body electronic system, such as non-functioning lights or power window failure. With years of workshop experience, I would first check the relevant fuses in the fuse box to see if they're blown, then inspect the wiring harness grounding for any looseness, damage, or poor contact. Aging of the BCM module could also trigger this error code - don't rush to replace it; test for stable voltage first. I recommend addressing this promptly as unresolved issues may lead to functional failures during daily driving, increasing accident risks. Just perform a thorough check before long-distance trips - it saves both money and hassle.
