What is the reason for the anti-skid off light on the Pajero after power failure?

It may be due to a malfunction of the anti-skid system and needs to be handled at a repair shop. Anti-skid off means the vehicle's electronic stability control system is turned off. More details are as follows: 1. Definition: The ESP function, known in Chinese as anti-skid, is an active safety feature. ESP is enabled by default, and in these cases, you need to press the ESP switch. 2. Working principle: Simply put, when the speed difference between the left and right wheels exceeds the threshold set by the computer, the computer will assume that the vehicle is skidding or fishtailing. It will then take appropriate actions such as braking individual wheels and reducing the engine output torque (controlling engine speed) to manage and prevent the vehicle from skidding or fishtailing.
When encountering the situation where the anti-skid OFF light comes on after a Pajero power loss, I think it's quite common, mainly because the system needs to reinitialize after the battery is disconnected or power is lost. The anti-skid system relies on the ECU and sensors, and power loss may cause the ECU to lose previous settings, preventing the system from starting normally and automatically switching to the OFF state. Additionally, sensors such as wheel speed or steering angle sensors may experience unstable connections due to power loss, leading to self-check failure. Sometimes, loose fuses or wiring connectors can also cause false alarms. My suggestion is to first drive a few kilometers for a test run, as the system may reset itself; if the light remains on, it's necessary to visit a repair shop to read the codes with a diagnostic computer or check the battery connections and fuse box yourself. Safety first—OFF means the system isn't working, significantly increasing the risk of skidding on wet roads when turning, so don't ignore this small issue. During regular vehicle maintenance, periodic checks of the electrical system can reduce such faults and extend the lifespan of the headlights, saving money in the long run.
