6.1 Viewing Trouble Codes
This mode views your trouble codes. A typical trouble code looks like the following
P0171
First Character – System
The first character identifies the system related to the trouble code.
P = Powertrain
B = Body
C = Chassis
U = Undefined
Second Digit - Code Type
The second digit identifies whether the code is a generic code (same on all OBD-II equipped vehicles), or a manufacturer specific
code.
0 = Generic (this is the digit zero -- not the letter "O")
1 = Enhanced (manufacturer specific)
