ELS27 v5 is a new car diagnostic adapter that combines full compatibility with ELM327, high reliability and speed of work with on-board networks of the car. The device supports work with CAN-bus and K-L-lines of cars. Can be used for diagnostics of various car systems, reading/resetting fault codes (DTC), enabling/disabling additional functions, modules and much more. Due to high quality of workmanship and stable operation, as well as low cost, the adapter has received wide recognition among repair specialists and owners of Ford and Mazda cars.

ELS27 adapter updates:

• New case
• USB Type-C

The protocol scheme has been revised and the connection (jumper) Pin 8 - Pin 9, as well as Pin 7 - Pin 12, has been removed. The mechanical relay has also been replaced with a separate transceiver and another one has been added for the CAN line on pins 12/13 (often used in Renault).

• FEPS on pin 13

Flash and EEPROM Programming Signal (FEPS) is a signal for switching ECU units to programming mode. It is used for Ford units manufactured before 2011.

• Flashlight
• LEDs on both sides of the case (if there is a wireless module)
• Buttons on the case for the wireless module

R - reset, resetting the module settings. M - mode, WiFi or Bluetooth mode (depending on the mode, the corresponding LED (B or W) next to the button lights up. Attention! This lot does not have a built-in wireless module!

• Modular structure of the adapter

The board with the processor and the interface board are two different boards, which means we can "update" earlier versions of adapters starting with v3.0 to v5.0.

• New silicone wire with PD 100W (Power Delivery)

The adapter supports the following car protocols:

Standard OBDII

• ISO 15765-4 (CAN)
• ISO 14230-4 (Keyword Protocol 2000 - KWP2000)
• ISO 9141-2 (Asian, European, Chrysler)
• SAE J1850 VPW (General Motors vehicles)
• SAE J1850 PWM (Ford vehicles)

Non-standard OBDII

• ISO 15765
• ISO 11898 (raw CAN)
• GMLAN Single Wire CAN (GMW3089)
• Ford Medium Speed ​​CAN (MS CAN)

Operating Rules

It is prohibited to:

• Connect the adapter to 24V on-board networks;
• When working with the adapter, use chargers of the "cigarette lighter" type that do not have a galvanic connection between the vehicle ground and the negative contact of the computer power plug;
• Leave the adapter in the vehicle socket for a long time without supervision.

The ELS27 v5.2 is a new automotive diagnostic adapter that combines full ELM327 compatibility with high reliability and speed of operation with vehicle on-board networks. The device supports the CAN bus and K-L lines of vehicles. Applications include diagnosing various vehicle systems, reading and clearing fault codes (DTCs), enabling and disabling additional functions and modules, and much more. Thanks to its high build quality and stable operation, as well as its low cost, the adapter has gained widespread recognition among repair specialists and owners of Ford and Mazda vehicles.

It is based on the FTDI FT232RL chip, the L9637D, and a Wi-Fi module. A USB Type-C to Type-C cable and a Type-A adapter are included.

The following changes have been made since version 5.0:

The "B" LED is now blue, not orange as in the v5.0 adapters, where the LEDs are powered by 3.3V, which is insufficient for blue LEDs with a voltage drop of 3.2V-3.8V.
The CAN bus on OBD pins 6/14 (the engine control unit bus) is connected directly to the transceiver. This change is not intended to improve anything (although it does add some stability), but it brings the circuit design closer to a "correct" implementation, where the main bus is always in place.
The backlight (flashlight) turns off when OBD power is restored.

CAN support on the following OBD pins (HI/LO):

• 3-11 (default)
• 1-8
• 12-13
• 13-12
• 1-9
• 3-8

ATTENTION! Switching between buses on these pins must be implemented in the software. The adapter does not have terminating resistors (bus terminators). These must be provided for use with desktop units.

- Compatibility with Wi-Fi modules is the same as v5.0, but the ability to update 16Mb Wi-Fi via wire is added (the v5.0 adapter only updates 4Mb via wire due to differences in the module's processor).

The ELS27 v5.2 adapter supports the following vehicle protocols:

Standard OBDII

• ISO 15765-4 (CAN)
• ISO 14230-4 (Keyword Protocol 2000 - KWP2000)
• ISO 9141-2 (Asian, European, Chrysler)
• SAE J1850 VPW (General Motors vehicles)
• SAE J1850 PWM (Ford vehicles)

Non-Standard OBDII

• ISO 15765
• ISO 11898 (raw CAN)
• GMLAN Single Wire CAN (GMW3089)
• Ford Medium Speed ​​CAN (MS CAN)
