I'll cut to the chase. My engine light has been on since new head gaskets were put on. I was researching how to turn the check engine light off and decided it would be wise to retreive the codes since I had found out it can be done in my year model Acura. I followed the instruction verbatum, found the wire connector right where it is supposed to be, inserted the paper clip in the connector, yurned the ignition key to "on" position, AND. Nothing. NO blinking lights sending me coded messages? Do you know what might be interferring with the process, lie a faulty watchamacallit or what. Is there another avenue or alternatve procedure for me to follow and get the codes?

HELP PLEASE Jamesmw11

SOME RIGS REQUIRE THAT YOU TOUCH THE BRAKES/ TURN ON THE IGN FOR X SECONDS/ SCRATCH YOUR EAR/ ETC. ALL IN A SPECIFIC ORDER.

THEN YOU HAVE TO COUNT FLASHES (WHICH CAN BE REALLY CONFUSING DUE TO THE SPACING DETERMINES WHEN THE 1ST DIGIT IS DONE AND NOW ITS FLASHING THE SECOND DIGIT. THIS COUPLED WITH TEST FLASHES PRIOR TO THE REAL CODE NUMBER

REALLY A PAIN!

IF YOU ARE GETTING NUTHIN', IT'S POSSIBLE YOU MAY HAVE A BLOWN FUSE (ON A OBD II TAHOE IT WAS THE CIGARETTE LIGHTER FUSE!)

YOU TUBE MAY OFFER A BETTER EXPLANATION ON "HOW"

THIS SITE SHOWS HOW ON OTHER VEHICLES (LIKE CLICK ON THE FORD LOGO) IT DOES NOT SHOW THE ACURA PROCEDURE (I COULD NOT FIND IT ANYWAY) IT DOES LIST THE CODES- HERE'S THE LINK

AROUND HERE, SEEMS ALL OF THE STORES CAN CHECK OBD II

HOWEVER, OUR "AUTOZONE" CAN HOOK UP AND CHECK OBDI WITH THEIR SCANNER, NO FLASHES, JUST CODE NUMBERS!!! (IF YOU CAN GET IT THERE!)

I HOPE SOMETHING HERE HELPS YOU! LET ME KNOW IF IT DID.

MOST QUESTIONS THAT DO COME HERE GET BETTER ANSWERS FROM THE BUNCH OF US, SO I HOPE YOU COME BACK WITH OTHER ISSUES IF YOU HAVE THEM, MAYBE YOU WILL CONSIDER MY ANSWER AS GOOD INFORMATION TO GUIDE YOU ALONG!

I'll check my fuses. I think they are OK, but never know, won't hurt any to see. I watched several videos on U Tube that were really good and they all were in sync with the process of how to do the retrieval and where everything is using the same year and make of my Acura. It's pretty simple really, after watching it done, over and over. Yea! So my thinking is that something in the system has a block up electrically. The fuses make sense like that, because the computer scans the whole system in the car basically, or so I'm told.
Thank you, when I find the solution I'll shoot it back to you so others may use the info as well.

Try this procedure

Roy

HOW TO DISPLAY AND READ DIAGNOSTIC TROUBLE CODES WITHOUT SCAN TOOL

When the Malfunction Indicator Lamp (MIL) has been reported on, do the following:

Zoom Sized for Print

Connect the Service Check Connector terminals with a jumper wire as shown. (The 2P Service Check Connector is located under the dash on the passenger side of the car.) Turn the ignition switch on.

Zoom Sized for Print

Note the Diagnostic Trouble Code (DTC) : The MIL indicates a code by the length and number of blinks. The MIL can indicate simultaneous component problems by blinking separate codes, one after another. Codes 1 through 9 are indicated by individual short blinks. Codes 10 through 59 are indicated by a series of long and short blinks. The number of long blinks equals the first digit, the number of short blinks equals the second digit.

Zoom Sized for Print

If codes other than those listed above are indicated, verify the code. If the code indicated is not listed above, replace the ECM.
The Malfunction Indicator Lamp (MIL) may come on, indicating a system problem when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary.
A/T: The MIL and [D4] indicator light may come on simultaneously when the MIL blinks 6, 7 or 17. Check the PGM-FI system according to the PGM-FI system troubleshooting, then recheck the [D4] indicator light. If it comes on, refer to TRANSMISSION CONTROL SYSTEMS
The MIL and TCS indicator light may come on simultaneously when the code blinks 3, 5, 6, 13, 15, 16, 17, 35 and 36. Check the PGM-FI system according to the PGM-FI system troubleshooting, then recheck the TCS indicator light. If it comes on, refer to TRANSMISSION CONTROL SYSTEMS.

DMy car is a 94" Acura Legend 2 dr. Coupe, so being that year 1994 there is no OBDI or II connector I have found anywhere nor have I heard there might be one. The connector wire end for the paper clip to start this thing living is where it is supposed to b, but when we follow instructions etc, and turn on the key, . No lights at all.I found another code retreval trick for my car that instructs us to fold back passenger side carpet and reveAl the CONTROL BOx in the floorboard. We did this and there is a red light and a yellow one which doesn't matter for this. The way this works is that when the check rngine light is on you turn the key to on (second) position, and the codes are supposed to flash on the red light, just like the dash light codes do. I got one red flash when I turned the key on, and one red blink when I turned it off. So, I will now try questionung the dealer for his stuff. This is Guam, USA here too, and nobody except a friend would read the codes free if they couls dO That With OBDI or II They charge minimum of $80 anywhere and UP. I'm sure they would flat refuse to read the hard way I'm trying. I don't care, I;ll stand on my head and sing if I can get the codes that way. Thanks for the input though, you never know what may happen next. Nothing so far
