As you are reading this you will probably be wishing to extract a fault code or clear a fault indicator lamp from the dashboard of your older Mercedes Benz model vehicle. Well the alternative information source you have been looking for is here, hopefully clear and accurate enough for your needs. I have collected the following information together in one place to save the frustration of trying to locate and find most that you would ever need to tackle this job.

I will not repeat what has already been expertly written on this subject, you can find links below to these sources to expand on what I have noted here. All was needed was a paperclip or short banana plug jumper to ground the required pins and simply watch the number of flashes. Codes are resolved from comparison of flashes to fault codes on a written list. This was commonly located within the ECU box and was accesses by removing a sealed access cap.

The reason behind this was that MB at the time had to comply with export requirements that necessitated access to emission data through OBD standard protocols. At this time Mercedes added the OBD port under the dash, in some cases near the steering column just to give access to emission related diagnostic codes, all the other electronic systems were dealt with through the 38 pin socket as before. So very much a hybrid situation was in existence — seemingly done as a quick fix to continue to sell cars in the US.

Without going into too much detail this new system used ISO communication protocol to access the vehicle electronics via a common communications module. This used both a K-line and L-line connection and Mercedes own communications language to access the system. Even though the communications standard of ISO is the same as used on OBD2 systems the way in which it talked to the modules was bespoke — and this is why you cannot use traditional OBD2 readers on systems of this type.

Fortunately Mercedes saw the error of their ways and only ran with this for about a six year window opting to take on the OBD2 standard across the board from Thank goodness! So given the above history there are three primary diagnostic code reading methods actually four that you may come across in the model year window of Please note all dates stated are approximate and for guidance only What is a little confusing is that Mercedes in their wisdom used the 38 pin diagnostic connector for both the analogue and digital systems making it very difficult to visually identify what system you are dealing with — they even used the same pin number allocations to reflect the connection to individual system components!

Select your chosen test point module connection to test from the following 38 pin socket diagram and connection pin-out table. Turn ignition on, engine not running. Press momentary switch for seconds, wait and then count flashes. Note down the number of flashes on a piece of paper. Repeat the process until the first flashed code repeats. After reading a code, press the momentary switch for seconds then release.

Please note not all pins are loaded in every model, the quantity of available pins depends on model, version and fitted equipment.

I have discovered that this period model The one I have! However that is about the extent of any function accessible by this method. As stated earlier above to read engine codes or ABS codes etc the unit has to be connected to a capable electronic code reader. This is because the protocol or access language is specific to Mercedes.

About the only system capable of reading and accessing the majority of codes through the Mercedes proprietary system is the Carsoft V12 system.

This is a Mercedes single model diagnostic tool made in Belgium. Its kit consists of a 7. For those fortunate to own post vehicles of the R stable your car should be equipped with a fully compliant OBD2 diagnostic system, 16 pin standard diagnostic port and the capability to be interrogated by most any off the shelf OBD2 reader. Lucky you! Instead of counting flashes, the AC console displayed fault codes on the two digit LCD temperature display and were cleared by a combination of pushing buttons.

Information for the reading and clearing of the diagnostic codes of the AC unit for the R can be found on page 90 of the Cs Baum Tools Manual.

On total diagnosis it only responds with 4 results, the rest failed to communicate, having selected the 38 pin digital. It look like this software is extremely limited in scanning this particular car. Hi Frank, Like all computer software it is a temperamental interface and you have to get things just right. It is most certainly not limited but I suppose is to the MB tools but is probably one of the best available tools for older diagnostics.

You will have to play with the settings a little to get the most out of it the settings for the port comms are critical and indeed you have to run it a couple of times on occasion to connect correctly.Your Mercedes vehicle will flash a host of service lights to inform you when something might be damaged inside the car.

Compared to its predecessor, the W had somewhat smaller exterior dimensions but offered more interior space, particularly in the long-wheelbase versions although the trunk is smaller than on its W predecessor.

Production of the series totalledunits, slightly more than the production totals from the W In many European countries, the diesel S CDI version became the most popular model, making it the first S-Class in which a diesel engine achieved broad appeal. There were long and short wheelbase versions, performance and luxury enhancement options, and also four-wheel drive versions. Steve Mattin's design was the first sketch drawn in October and developed into scale by late By MarchW program engineers completed the design freeze, 29 months before production start in August The W exterior design especially headlights was previewed by the Mercedes-Benz F concept in late Being a Mercedes flagship vehicle worldwide, the S-Class largely popularized the theme.

It demonstrated a significantly different stylistic mindset, with both exterior lines and an interior design that expressed elegance and modernity.

This can be seen as a response to criticism on its W predecessor, which had a more boxy look. Despite being smaller, the new car was roomier inside while the dashboard carried over the new styling details first seen in the first generation A-Class from the year before.

A face-lifted version of the S-Class was designed in late and introduced in Septemberoffering a more refined front-end with a larger, more upright grille, transparent headlamp housings with sealed-beam projectors, and revised taillights.

Much of the rest of the exterior remained largely unchanged from first phase W models. Exterior updates included a more upright grille angle, new transparent housing for the headlamps replacing the earlier translucent versionsand restyled lower air intakes on the front bumper. The S series has a "V12" badge affixed to either side of the car, just forward of the front doors and back from the wheel wells.

After the Ohtani news, that went to 30-1. Japanese star Shohei Ohtani's signing with the Los Angeles Angels had ripple effects in Las Vegas as well. The Angels go from 50-1 to 30-1 to win the World Series at the Westgate Las Vegas SuperBook. With their new odds, the Angels would be in the same category as the Tampa Bay Rays, Toronto Blue Jays, Seattle Mariners and Milwaukee Brewers.

Note that those odds are from November and may have changed since then. When Westgate released its odds in November, the Angels were tied with the Chicago White Sox, Atlanta Braves and San Francisco Giants at 50-1. While Ohtani should help the Angels, the team is still considered a fringe playoff contender according to Las Vegas.

None of the teams with 30-1 odds made the postseason in 2017, though many came close. That includes the Angels, who finished at 80-82. Many believe Ohtani can be a difference-maker, at least on the mound. If Ohtani is that good, you might as well put your money down now, because it would be tough to see the Angels miss the postseason with the next Babe Ruth and Mike Trout on the same team.

Actually, you might want to put your money on the Angels even if you believe Ohtani is merely a good player instead of a legendary one. The level of uncertainty surrounding Ohtani could mean Vegas is underrating him at the moment.
