What is the reason for the KAM restart failure in the Buick Excelle?
2 Answers
Check whether the battery is loose, and check whether the engine computer harness is loose. If there are no issues with these, it is likely a problem with the computer. The following is an introduction to the new Buick Excelle: 1. Dimensions: It is a compact car with a body size of 4609mm in length, 1798mm in width, 1486mm in height, a wheelbase of 2640mm, a fuel tank capacity of 44 liters, and a trunk capacity of 400 liters. 2. Powertrain: The new Buick Excelle is equipped with a 1.0T turbocharged engine, delivering a maximum horsepower of 125 PS, a maximum power of 92 kW, and a maximum torque of 170 Nm, paired with a 6-speed manual transmission.
I've been driving for over a decade, and KAM (Keep Alive Memory) resets in Buick Excelle are quite common. Simply put, it's when the vehicle's computer memory module malfunctions, acting like it has amnesia. The most frequent culprit is the battery, especially in older cars where low battery voltage causes unstable power supply, making the module constantly reboot. Other causes include oxidized/loose wiring connections, blown fuses, or faults in the control module itself. Once when helping a neighbor diagnose this issue, I found it was caused by interference from improperly wired aftermarket dashcam. My advice: first check battery voltage with a multimeter, then inspect the fuse box and wiring harness connectors. If your clock resets after parking or fuel consumption suddenly spikes, this is almost certainly the issue. If left unfixed for long, power hesitation will become more noticeable.
