As we know all cars manufactured after 1996have to equip with generic second generation On-Board Diagnostics as well as OBD2 codes specific to cars. Also Chevrolets are without exception. Chevroletsbuilt before 1996 use special, first generation OBD codes specific only to GM cars.Since 1996, all cars regardless of the makeor model use the same basic OBD diagnostic codes. These codes are the same onFords, Toyotas, Jeeps, Kia, BMW and every other car containing thosemanufactured by Chevrolet. OBD 2 codes show problems in different areas of the car.These areas are identified by the first character of the code. "P"stands for power train faults; "B" stands for the body problems;"C" stands for chassis electronic malfunctions; and "U"stands for network communication problems. The code will be deferent betweenOBD2 and OBD 1.General Motors OBD 2Chevrolet, Buick, Oldsmobile and GMC areall the subsidiaries of General Motors. While the OBD 2 system was planned tostandardized diagnostics, wiggle room was left, permitting manufactures todefine extra codes as needed. After all, no two brands of engine are exactlythe same. The manufacturer-specific OBD 2 codes use the same format as thegeneric codes and use the same character prefixes to define the part of the carwhere the trouble has been detected.Distinguishing Generic from GM OBD 2Once trouble codes have been retrieved froma Chevrolet's diagnostic system, there is a method to tell which codes aremanufacturer-specific. For power train codes, any code beginning with P1, P30,P31, P32 or P33 is manufacturer-specific. For chassis codes, any code beginningwith C1 or C2 is a GM code; GM's network communications codes begin with U1 andU2, and GM-specific body codes all begin with B1 or B2.General Motors OBD 1Most Chevrolet cars manufactured before1995 use a flash code system of OBD 1. The diagnostic system can be placed intoself-mode and the error codes within the system will be relayed by a flashing"Check Engine" light. The codes can be diagnosed by counting thenumber and length of the flashes. GM error codes are two character numbers --the first number is represented by long flashes and the second by shorterflashes.How to AccessOBD 2 codes just require a special,handheld OBD code reader or scanner. This device can be bought at most carparts stores. The scanner inserts in to the Chevrolet's data outlet, which isunder the driver's side dashboard. Each device differs in how codes areretrieved so it's necessary to look up the scanner user manual for specificinstructions. An OBD1 self-test does not use a scanner. Instead, the system canbe jumped by connecting the "A" and "B" slots in the car'sdata port. Then, powering on the electrical system will activate the CheckEngine light to begin flashing.
