Hi Guys;

Been having the limp-mode problem with my sonata, and I'm pretty sure it's one of the speed sensors, as it shifts fine for a few minutes and then hits limp.

I have been reading hmaservice.com with regard to getting DTCs from a 1997 sonata. It says to ground pin 1 and measure voltage on 15, however I'm not sure if this is correct. Can someone please shed some light on this, specifically what pins these are (on the connector in the fuse box) as they are not numbered, and the voltage range I should be looking for.

A picture of the connector with the pins pointed out would be really helpful

Thanks in advance,

shannon

 

Here is a diagram of the pinouts on the D-shaped data link connector located under the dash. You are not measuring voltage, perse, but counting the swings or spikes in voltage. You count the number of consecutive long spikes and then the number of short spikes to come up with the code. Some guys have wired an LED circuit to this connector to count the "flashes". When I use to diagnose problems on a 87 Chevy pickup I once had in similar fashion, I found an analog meter (with a swinging needle) was easier to count than a digital one. Make sure you have pin #1 connector to the volt meter first. Grounding pin #15 is what starts the error code sequence. Also, I think the the first one or two voltage spikes (which last several seconds) are initiation sequences that don't count.

 

Hey mate, thanks for the info,

here is what the connector looks like, it's not the standard OBD2 connector, if it was I could simply use my scanner to read the codes.

Do you have the pinout for this connector by any chance? or am I looking in the wrong place?

 

"MATE" ??? I take it this is maybe not a USA vehicle ??

HMA Service shows OBD-II connector located at left lower dash panel..

Sit in seat (assumunig left hand drive USA) and where right knee might could hit lower panel in line above gas pedal... the OBD-II port is shown to be there poking through the dash panel...

Go look....

1997 USA had to be OBD-II compliant, so look for that black connector poking through the lower dash panel...



HMMMMMM,,, looking at larger pic of fuse block door and accell pedal, it looks like we have a right hand drive car.... maybe not OBD-II being non-North American vehicle

 

I'm a Sonata user from Thailand. That connector is exactly located the same place to mine. Yes, it's non OBDII and I think my 1997 Sonata has no the second(downstream) H2OS after the CC(Catalytic Converter).

 

I read in my repair manual, DTC is read by using the most up-right(MPI Diagnosis) and most down-left(ground) pins for OBDI (pulses represent 2 digits DTC, they can be found on www.hmaservice.com).

 

I just found a useful link for reading "Korean" VIN, which answers my question why the 9th digit is "P" not a number and my 8th digit is F (1975cc, shold be Tiburon in USA and Canada but it's 1997cc Sonata by the link).

The right place, here is the pinout...;-)

I got the same connector in a 98 model Hyundai H1
Only pin 1,2 and 12 in use
According to data it should be ISO 9141
I tryed to scann with KKL Vagcom cable, no contact
I tryed the flash with multimeter, but no activity....
(Went to one dealer who din't have the right scanner)

Most interested to scann pinn 2 air bag, the air bag light is solid.

Any tip is welcome...;-)

 

There are 2 video clips about reading the DTCs on my Youtube.
