How to Modify ELM327 to add HS/MS CAN Switch

Posted on by sales

Notice: My successful diy experience on “Add HS/MS CAN Switch” via ELM327 is only for your reference. I do not confirm all of you can test it successfully.

Most Ford and Mazda models (approximately since 2) are equipped with MS CAN Bus, while MS CAN Bus is not supported by ELM327 Bluetooth OBD2, because MS CAN is a manufacturer-specific solution and located on non-OBD2 pins.

While ELM327 is a very flexible tool and slight modification allows to implement the MS CAN support. Therefore, let’s come to the process on “How to modify ELM327 in order to add the HS/MS Can switch” below:

1.5V ELM327 Scanner supports HS CAN from the stock, because Ford HS CAN completely matches to the OBD2 standard. It occupies pins 6 and 14. MS CAN bus occupies pins 3 and 11 (illustrated below).

ELM327 1

The simplest way to implement the MS CAN support is to add a switch that will shift between MS/HS CAN. The scheme below explains the modification:

ELM327 2

Roadmap:

1. Purchase a 6 pin mini-switch of ON-ON type (for example, MTS-202-A2) in any shop that sells electronic components, also prepare a wire.

ELM327 3

2. Disassemble ELM327 (carefully remove the label that hides 4 screws, unscrew them).

3. Find a place for mini-switch (most complex part of the whole operation for some devices that are extremely compact).

4. Unsolder wires from pins 6 and 14 of the OBD2 jack and solder them to the 2 middle pins of the mini-switch.

5. Solder 2 new wires from 2 outer mini-switch pins to pins 6 and 14 of the OBD2 jack.

6. Solder 2 other new wires from 2 other outer mini-switch pins to pins 3 and 11 of the OBD2 jack.

7. Check the work (it is very important to do not mix CAN-L and CAN-H wires up) and assembly the ELM327, mark the MS and HS can position on the device box to avoid confusion.

So far, all steps done. Hope it indeed helpful to you.

ELM327 OBD2 WIFI Auto Scanner for IPhone Ipad IPod

Posted on by sales

ELM327 obd2 for iPhone,iPad is able to detect and interpret these protocols automatically. ELM327 obd2 scanner also provides support for high speed communications and a low power sleep mode. It use AT commands to communicate with a host device (PC, notebook, iPhone, iPod touch, iPad and so on). There are plenty of software packages available, which are fully compatible with WI-FI OBD AUTO CHECKER. Some of them have pretty useful features, such as engine running parameters monitoring, DTC reading and clearing, MPG meter, etc. You can even write your own software on a specified hardware platform if you wish, because the AT commands are fully documented and very well explained.

 

WI-FI OBD AUTO CHECKER is measuring only 2.7 x 1.25x 0.9 inches.It comes included with a power switch built-in to prevent the need for having to constantly disconnect your unit from the OBDII port. It is compatible with 1996 and later vehicles. Connecting to your iPhone / iPod touch /iPad is made by WIFI connection in adHoc mode.

 

Elder OBD compatible vehicles has a sticker indicates that the vehicle is OBD compatible. Model year 1996 and newer vehicles are compliant by default, and will not have this sticker.

Following are some of the parameters which could be read from the vehicle.
