What is the reason for the intermittent operation of the Xiali A+ odometer?

The reasons for the intermittent operation of the Xiali A+ odometer: If it is an electronic odometer, the fuse may be blown; if it is a mechanical odometer, the connecting wire may be loose. Determining whether it is a sensor or instrument malfunction: Lift the left front wheel of the car, do not turn on the ignition switch, manually rotate the left front wheel, and use a dedicated test connector VAG1598/4 and a multimeter to measure the resistance value between electrodes 2 and 3 on the sensor connector. The resistance should oscillate between 0 and n. Determining whether it is an instrument or wiring malfunction: Remove the instrument panel without unplugging the connector. Use a multimeter to measure the three electrodes on the instrument. With the ignition switch turned on, the voltage from fuse No. 26 to the power line of the speedometer should be 12V to ground. Use the multimeter's resistance mode to measure the pulse signal line resistance from the instrument to the sensor connector, which should be zero, and the ground electrode resistance to ground should also be zero.
I've been experiencing erratic behavior with my odometer while driving, and it's really annoying. As a long-time owner of this car, I suspect it's mostly due to a loose or rusted sensor, where intermittent signals occur if the connector isn't properly secured. Aging or cracked wiring could also prevent current from passing through, causing the odometer to malfunction due to incorrect readings. Internal wear or dust buildup in the motor might be another culprit. I recommend first checking the sensor near the driveshaft and tightening the connector. Don’t ignore this issue—an inaccurate odometer can mess up maintenance schedules and even compromise safety. Older cars often have minor electrical gremlins, so ask your mechanic to take a quick look during routine servicing to avoid costly repairs later. Safety first—fixing it will give you peace of mind.
