You cannot obtain codes from the motronic system without a euro flashed scanner.Sorry but you'll have to go to a shop to pull codes.

Connect white (test lead) and black (ground lead) wires that are branched from harness approximately eight inches from ECM. After leads are grounded, the "Check Engine" light will flash the diagnostic trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.I-MARK 84-85
Connect male and female test leads taped into wire harness near ECM. After leads are connected, the "Check Engine" lamp will flash the trouble codes. The DTC's are indicated by the flashing CEL.
FLASH, FLASH, pause, FLASH, FLASH, FLASH = Code 23.
If only one diagnostic trouble code is stored, the DTC will repeat continuously until test leads are disconnected. If more than one diagnostic trouble code is stored, each DTC will repeat three times, starting with the lowest, then proceed to the next DTC. After all DTC's have been displayed, the pattern will repeat.
86-87 Impulse located near the ECM connector, is used to actuate the Engine Control Module (ECM) trouble code memory within the module. Two terminals (A and C) of this connector are used to activate the diagnostic trouble code system in the ECM. With the ignition switch turned On, engine Off, connect a jumper wire between terminals A and C. The "Check Engine" lamp will begin by flashing a DTC 12. DTC 12 = flash, pause, flash, flash. There will be a longer pause and a code 12 will repeat two more times. This code indicates the self-diagnostic system is operating. The cycle will then repeat until the engine is started or the ignition is switched Off. In most cases, DTC's will be checked with the engine running since no DTC's other than DTC 12 or 51 will be present without the engine running. Remove jumper wire from ALDL connector before starting engine. Reconnect jumper wire after engine is running.

Throttle Body Fuel Injection

The ECM test connection is located under the center console.
A built-in, self diagnostic system will identify problems in the throttle body fuel injection system. When a problem is detected, the diagnostic system will illuminate the "Check Engine" light.
When the engine is started, the Check Engine light should turn off.. If the light remains lit, the self diagnostic has detected a problem. To determine where the problem exists, ground the "Test" terminal of the connector with the ignition On, engine Off and watch the check engine light. Each DTC will flash three times (lowest to highest).

How to reset engine lite in dash


Check engine light comes on and off, these are indication that there is some error code stored in your vehicles ECM. The engine module computer needs to be scanned. These will give the code and as per the error code the further problem can be detected and confirmed. The engine light indicator blinks or remains steady on dash when engine computer noticed any problem with any engine electrically operated components.

What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

My check engine light comes on and stays for a while than goes off I thought that I smelled rubber today, what could it be


have your obd II CODES READ this will give you more of an idea what is going on with it. most auto parts stores read these codes.

Check engine light on need to know where plug is to check what problem is


Extracting Fault Codes:
Turn the ignition switch ON, OFF, ON, OFF, ON and observe the CHECK ENGINE LIGHT. The CHECK ENGINE LIGHT should begin to flash a series of codes. The flashes will be long and short. The long flashes are the "tens" and the quicker flashes are the "ones" representing the numbers of each code. There will be a slightly longer pause separating each code from the next. A code 55 will be displayed at the end of the test.

Take the vehicle to Auto Zone, advanced Auto parts or o'Rieley's Auto parts and ask them to use their scanner to read the stored Code from the ECM for you.

Check engine light on


Cycle your key, on (not start) off, on, off, on. Leave it on 3rd time, and count check engine flashes. It will be a 2 digit number each time. For example: flash,flash, pause, flash, flash. Is code 22.
Flash,flash,flash,pause,flash,flash,flash, is code 33. There will be a little longer pause after each set of 2 digits. When you get flash,5 times, then flash 5 times again, that's code 55 which means end of trouble code message. have a piece of paper ready, write them down, and get back to us with results.
