SRS Diagnostic using DRBII:

      Updated 2/1/08

      When I went to sell my 3000GT I had to finally fix the SRS light. My hatred of dealers put me on a quest to get a
      DRBII or MUTT II so I would never have a reason to go to a dealer again. I got screwed over multiple times on EBAY
      by people selling DRB units that appeared to be complete but were missing cartridges or adapters. I also bought untested
      DRB units just to get the cartridges. As I expected untested meant they were broken. It took almost 5 separate EBAY
      auctions at a total cost of $1400 to get 2 functioning DRB II units. It was still cheaper than what the dealer wanted
      to fix a G-force sensor error code, so it was still a good deal. I felt that I should share my experiences so other 3S
      owners will not have to struggle as much as I did. I also started a thread on 3SI with pictures:

      If you want to diagnose the Airbag (SRS) system on your car you will need a DRBII or a MUT II.
      The Mitsubishi version is a MUTT II but I have never used a one and the DRB II unit worked on 3000GT’s too.
      A DRBII is a special dealer only diagnostic tool that was not sold to the general public.
      Now that newer versions are available you can often find them on EBay.
      If you buy from EBay you need to make sure you get every part you need.
      A DRB III is the newer version but it costs around $3000 on Ebay. If your car is newer than a 95 you are stuck
      paying big bucks or going to a dealer. If you are buying a DRB II unit on Ebay make the seller verify that it
      works and make sure you get the necessary parts listed below.

      The following parts are REQUIRED to use a DRBII.
      1. DRBII Main control Box. DRBII Main control Box. This is a 4.5x8” box with digital display and a fairly large keypad.
      2. DRB Cartridge for your car. The best cartridge is a “Super Cartridge” A Super Cartridge covers multiple years
        and cars. A very desirable cartridge in the blue 91-93 Super Cartridge. This will work for All 91-93 Chrysler,
        Dodge Stealth 3000GT and DSMs. The best cartridge I know of is the Yellow label 1983-1994 Super Cartridge
        Most DRBIIs are sold with no cartridges at all, or a cartage that has very limited usage so be carefull.
      3. MMC Adapter (P/N MM1000). This is a 3x6” box with wiring harnesses that allow a DRBII to connect to a DSM,
        3000GT or Stealth. Many DRBII are Not sold with this adapter but I have found the adapter sold separately.
      4. 94 Y-cable. This harness is only needed to connect to 94 & 95 DSM, 3000GTs and Stealths.
        Please Note: If you do not have a 94 compatible cartridge this is useless.


      The following parts are OPTION to use a DRBII or parts not used on 3000GT or Stealth.
      1. Jeep/Eagle Adapter (P/N JE1000), This is a 3x6” box with wiring harnesses that allow a DRBII to connect to a
        Jeep or Eagle. Many DRBII are Not sold with this adapter but I have found the adapter sold separately.
        THis is NOT needed with some Jeeps/Eagle. I do not know the exact usage of this yet...
      2. Co-Pilot. This is a data recorder that is installed in car. When intermittent problem occurs you hit a
        button to record. A DRBII is needed to download the stored data.
      3. SRS diagnostic Manual. The DRB is Really easy to use but this helps to figure out airbag codes.
      4. SCI Cable (P/N CC2000) This is the Engine Diagnostic cable for Chrysler cars. Not needed on Stealth or 3000GT
      5. CCD Cable (P/N CC1020) This is the Body Cable for some year Chrysler cars. Not needed on Stealth or 3000GT

      AIRBAG (SRS) DIAGNOSIS:
      Connect the DRBII to the vehicle as follows.
      1. FIRST Read 3000GT factory SRS diagnostic manual!
      2. Connect the 8-way DIN connector of the DBRII to the 8-way DIN connector of the MMC Adapter
      3. Plug the 12-way diagnostic connector of the MMC Adapter into the diagnostic connector of the vehicle.
        The vehicle’s diagnostic connector is located on the LH side of the dash next to the fuse box.
      4. Attach the red alligator clip the battery positive terminal. Note: attach the red alligator clip last,
        after the other two connectors are connected.
      5. Turn the Vehicles ignition switch to the “RUN” position. Note: Do not touch the keypad during the DRBII
        power-up sequence or an error will result.

      The DRBII will display the vervsion and rev level of the software for a short time.

      After A few seconds the main menus will come up Note the menu is larger than the display screen so you will have to
      use the down arrows to see all of the options.
