A 2014 Maserati Ghibli with a 3.0T engine has accumulated approximately 74,000 miles. The owner reported that the driver's side window could not be raised after it was lowered to the bottom. The garage operated the driver's side window glass lift switch and found that the left front glass lifter did not work, while the other three windows lifted normally. Pico oscilloscope detection, the driver's side door control module (DDM) stored in a number of fault codes (Figure 1), suggesting that the message points to an internal failure of the DDM.

2021款Toyota Wildlander PHEV車，搭載A25D-FXS發動機和動力蓄電池系統（額定電壓為355.2 V，額定容量為45.0 A·h）累計行駛里程約為1萬km。Pico示波器測量凸輪軸和曲軸位置傳感器的訊號波形，分析可知，進、排氣凸輪軸位置傳感器的信號形狀一致，均為周期變化的3個寬度不同的脈衝訊號

一輛2015款賓士 G63 AMG車，搭載157發動機，累計行駛里程約為9.4萬km。車主反映，該車低速行駛時，發動機偶爾會自動熄火，故障大概1個星期出現1次。用 Pico示波器測量曲軸位置傳感器訊號、低壓燃油壓力傳感器訊號、燃油泵 U相電流及燃油泵 U相端電壓波形，診斷故障原因。

一輛2013款奧迪Q5車，搭載 2.0T發動機，客戶進廠報修駕駛人側電動座椅無法調節。詢問客戶得知，該車在其他維修廠維修過，當時更換了駕駛人側電動座椅開關總成，可沒使用幾天故障再現。利用pico汽車示波器幾側故障狀況並排除。
