How to turn off the VSC light on the Reiz?

Methods to eliminate the VSC light on the Reiz: You can turn off the engine and restart it to check if the light is still on. If it turns off, you can drive normally; if it remains on, you will need to visit a 4S store or a professional auto repair shop to have a technician inspect and determine the issue before performing the necessary repairs. Problems with any component in the intake system, fuel system, or ignition system can trigger the VSC light. The Reiz is a model under FAW Toyota. In terms of body dimensions, this car measures 4750mm in length, 1795mm in width, and 1450mm in height, with a wheelbase of 2850mm. The Reiz is equipped with two powertrains: the Toyota 5GR-FE V6 all-aluminum engine and the 3GR-FE V6 all-aluminum engine, both featuring DOHC dual overhead camshafts and DUAL VVTi.
My Reiz had the VSC light come on last year too, and I figured this needs a step-by-step approach. First try the simplest solution - turn off and restart the engine, sometimes the ECU just glitches with false alarms. If the light stays on, immediately check the brake fluid reservoir and fluid level - Toyotas often have this issue where the switch on the reservoir cap acts up when low on fluid. If those check out, it's 80% likely the wheel speed sensors need inspection, especially the rear wheels where dust buildup or loose connectors are common. I've also discovered a less known scenario - if you've modified with coilover suspension, the height sensor might have shifted causing errors. Personally, I bought an OBD scanner to check the trouble code - C1256 indicates an issue with the brake booster pressure sensor. The fix isn't complicated, but some components require a shop's computer to reset the codes - safety first after all.
