REDUCED ENGINE POWER. Read below and please help me understand this.
How do I check CAN BUS on my 2005 z71 Tahoe. I understand how to do it through a 16 pin OBD2 port but have no idea how to do it on my Tahoe due to it only having 4 pins in the OBD2 port. Ima supa confused. It has two grounds, data wire, and power wire or voltage wire. Any help on this is much...- stretchit
