Where is the obd2 connector location on holden ra rodeo v6


isuzimpuls.gif
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.

1991 CHEVY S-10 4.3 2X2 AUTO TRANS, TRUCK RUNS GOOD BUT WHEN IT REACHES NORMAL OPERAING TEMP THE SERVICE ENGINE SOON LIGHT COMES ON


There is no way to tell what the light is for without scanning for trouble codes.There is a way to access the computer trouble codes without having a code reader. If you look under the driver side dash near the steering column, you will find the diagnostic port where you would plug in a scanner. If you look closely you will see that the terminals are identified as a,b,c, and d. Take a metal paper clip and straighten it out, then bend it into a u-shape. Put one end of the paper clip in terminal A, and the other end in terminal B. Now turn the ignition key to the on position, but do not start the engine. The check engine light will start flashing. This is how you will get the codes, by counting the flashes. The check engine light will flash the number 12 three times, to let you know that it's getting ready to flash a code. Let's say the computer has stored a code 32, and a code24. First, the number 12 will flash 3 times(flash-pause-flash flash). Then there will be a long pause. Then the computer will flash the first code, which, in this example, is 32(flash flash flash-pause-flash flash). It will flash the same code three times, then it will flash the number 12 again. After the third number 12 has flashed, the next code will flash, which is 24(flash flash-pause-flash flash flash flash). That code will flash 3 times. Then there will be a long pause, and the pattern will be repeated. After all the codes have been flashed, the whole sequence will be repeated, starting with the first code, and will continue as long as the paper clip is in the diagnostic plug. Write the codes down as they are flashed. If you get mixed up, just wait for the next sequence of the number 12 to flash, then start counting the flashes again. Believe me, it takes a lot longer to type all this out than it does to get the codes off teh computer. If you have any questions, let me know. When you have the codes, I can look them up for you and see what they represent.
