A Buick GL8 Lu Zun car after parking, sometimes fails to start the fault, but sometimes can start, the instrument shows abnormal, and sometimes brake warning light will be lit, tachometer does not move and so on, and sometimes the phenomenon of failure disappeared. Through the computer test found that the CLASS2 communication code, see the relevant circuit diagram, first check the line and found that the rear air conditioning control module harness connector corroded liquid, causing the line short circuit, resulting in the engine can not start.
