OBDII Manufacturer Specific Trouble Codes for GM

OBDII Manufacturer Specific Trouble Codes for GM

The rules for OBDII require all manufacturers to utilize a set of global/generic trouble codes. This is a partial list of OBDII Manufacturer Specific Trouble Codes for GM. Manufacturers are allowed to use “enhanced/manufacturer specific” powertrain codes that start at P1XXX and go up from there. Inexpensive scan tools usually can’t read enhanced codes. Plus, there are Body “B” codes, Chassis “C” codes, Communication “U” codes that the cheapo units can’t read.

Parts store units usually only read generic powertrain P codes. GM trouble codesSo you could go to a parts store and get a “no code” yet have an enhanced code or a code in another system.

NOTE: NEVER replace a sensor or component simply because that component’s name is mentioned in the trouble code. That’s the single most common DIY mistake. In fact, parts manufacturers tell us that 80% of sensors (especially oxygen sensors) replaced by DIYers are actually good. DIYers simply jump the gun and replace the part, ignoring the possibility that the sensor may be accurately reporting the values it sees, meaning that you have an underlying air/fuel problem

Next, understand that not all code readers are capable of reading all possible codes.The rules for OBDII require all manufacturers to utilize a set of global/generic trouble codes. But manufacturers are also allowed to use “enhanced/manufacturer specific” powertrain codes that start at P1XXX and go up from there. Inexpensive scan tools usually can’t read enhanced codes.

Codes gmc obd2

Do you have a GM vehicle between 1980 to 1995? If so, there is a big chance your car has an OBD1 connector (ALDL).

This connector is unique and applies to Pontiac, Chevrolet, GMC, Oldsmobile, Cadillac, and Buick, and more. The positive thing with the OBD1 connector is you can read your trouble codes at home without any diagnostic tools.

There are special diagnostics tools for this kind of connector, but they are not necessary as you can read them just as well without a tool.

If you have a newer car after 1996, you have OBD2 codes in your vehicle and this article will not apply to your car. You can check our other article with OBD2 codes.

OBD1 Trouble Code List

Here is a complete OBD1 trouble code list. The OBD1 codes’ meanings can differ a bit depending on what car model you have, but most of them are the same among all car manufacturers. We do not take responsibility for any faults in this code list. Check your repair manual for the trouble codes of your car model.

CodeDescription
12System OK ( Diagnosis mode active )
13Oxygen O2 Sensor – Circuit open/no activity
14Coolant Temperature sensor – Resistance too high or shorted circuit
15Coolant Temperature Sensor – Circuit low or open
16Direct ignition system (DIS) – Faulty circuit / shorted circuit
17Camshaft Position Sensor – Circuit/timing error

OBD1 Connector Location

Obd1 Connector

The OBD1 connector is usually located under your steering wheel, under the dash. The connector may have a black plastic cover, which you have to remove before accessing it. The connector is often black and has 12 pins on it; pretty easy to identify.

Check the image above to see what an OBD1 connector looks like

OBD1 Connector Wirings Pinout

The OBD1 connector has 12 pins, but not all of them are used in most car models. The standard pins like the ground, power, and a diagnostic pin are the same in most car models though.

Make sure you connect your wires correctly, as if you are not careful, it may damage your vehicle’s electrical system and control units, which can be very expensive.

This is how the pinout of the OBD1 connector looks like in most car models, check your repair manual for the exact pinout:

Obd1 Pinout
  • A = Ground
  • B = Diagnosis Terminal
  • C = A.I.R
  • D = Service engine soon light
  • E = Serial Data
  • F = T.C.C
  • G = Fuel pump
  • H = Brake Speed input
  • J = None
  • K = None
  • L = None
  • M = Serial Data

How to Read OBD1 Codes at Home

Obd1 Jump Wire

Our reading method without a diagnostic tool is to make short the circuit of pin A and pin B. The car will then enter the diagnostic mode and flash the “check engine Light” several times, and we should count the flashes to figure out the diagnostic codes.

How to read the OBD1 codes:

  1. Always connect a car battery charger to your car when doing any electrical work that requires the ignition to be on. Low voltage can cause a lot of trouble with the troubleshooting and many error codes that we do not want.
  2. Put a jumper wire between PIN A and PIN B.
  3. Let the jumper wire sit there and turn the ignition to ON. Do not start the engine.
  4. The check engine light will begin to flash. Count the flashes. There will be a longer pause between the codes if you have several trouble codes and a shorter pause between the trouble codes’ digits. For example, code 16 = 1 flash * Pause * 6 flashes.
  5. When all trouble codes are outputted, it will flash the code 12 – 1 flash * Pause * 2 flashes.
  6. Write down all the trouble code numbers you got and check the trouble code table further down in the article.
  7. Remove the jumper wire and car battery charger.

OBD1 Code Reader

Obd1 Code Reader

There are also a lot of OBD1 code readers on the market to make the job easier. With an OBD1 code scanner, you do not have to short the connector, and you do not have to count the flashes on the dashboard.

You will get the problem in clear text on your device, and this is, of course, a great investment to make if you are reading a lot of trouble codes from older vehicles.

There are several different code scanners on the market in all different price ranges. Some scanners can read both OBD1 and OBD2 codes, but these are pretty expensive. One really affordable scanner that I found is the Innova 3123. You have two different options, Ford or GM vehicles, you can choose from. If you want to take a further look at the scanner, you can find it here on Amazon:

We are alone, there are no neighbors. Even if they were, we are on our territory, there is a dense hedge around us. You continued reading without paying attention to the fact that I pout and prepare an insidious plan.
