Introduction

Introduction
This document describes the characteristics of the On Board Diagnostic system
(OBD) used by the ECU and assembled on the 2017 Marathon Euro 4 PRO.
The OBD system checks and shows one or more faults concerning:
• Emission up to Euro 4 limits.
• Engine power limitation.
On this document you can find all information needed to solve the OBD Errors
found on the bikes.
The components checked by the OBD System are:

OBD System

OBD System
The ECU is provided by the OBD system, when the OBD detects a failure it
shows the following symbol on the dashboard:
To know the cause of the failure you will need to connect to the ECU with a
OBDII reader, this tool can be show the diagnostic Error and erase it, once the
error has been erased the symbol on the dashboard will switch off, if after
erasing the failure the symbol continues it means that the problem is not solved.
When the problem disappears, the error is automatically erased after 10
complete cycles of use (bike running around 5 minutes), for example if one
customer unplugs the temperature sensor switch the error symbol will appear, if
they reconnect the connector the error will disappear after 10 uses.
Specific tool
To connect the bike at the OBDII reader is necessary have on harness adapter
to connect the standard connector of the bike to the connector SAE J1962 Type
A use on the OBDII readers.
Rieju has the next part available to use the OBD systems:
0/000.160.6022 – HARNESS SUPPLEMENT OBD E4

System for auto diagnostics
0/K00.160.6000 – KIT OBD READER WITH HARNESS SUPPLEMENT
If you have a standard OBD reader you will need only the harness supplement
to connect it with the ECU of the bike. If you dont have an OBD reader Rieju
suggest use the KIT OBD READER WITH HARNESS SUPPLEMENT, this kit
has been tested on Rieju bikes and its operation is guaranteed
Connection OBD reader with the bike
The OBD connector is placed under the seat next to the battery cables.

OBD System
1. Check that the key is in OFF position.
2. Take out the cap protection.
3. Plug the OBD harness supplement with the main harness.
4. Plug the OBD reader on the harness.
5. Turn ON the key (it will not necessary run the bike).
When the key is in the ON position the OBD reader will switch ON
automatically. Look at the OBD reader instructions to know the error codes and
erase it if necessary.
If the OBD reader does not switch ON, and the OBD reader is not supplied by
Rieju it’s possible that your OBD reader is not compatible with the OBD II
system and you will need replace it.
If the OBD reader is provided by Rieju but it cannot switch ON please check the
battery is correctly connected and is full charged, check the fuse of the main
harness and the harness supplement. If the problem continues contact with the
Rieju after sales department.

Error code

Error code
Once the OBD reader is connected with the ECU we can found the following
error code:
Code
Component
Error
P0601
ECU
Internal error
P0335
Pick-up sensor
Open circuit or value out of tolerances.
P0118
Engine temperature
sensor
Resistance value on the limits.
P0117
Engine temperature
sensor
Resistance value under limits.
P0351
Coil
Primary resistance value on the limits.
P2300
Coil
Primary resistance value under limits.
P0601 error:
This fail means an internal ECU fail, check the following points:
1.- Check the correct status of the battery.
Nominal voltage will 12,5 V en DC
Clean the terminal and check the correct contact between the terminals and the
harness.
Put the key in ON position and run the bike, with a multimeter in 20V DC
position check the correct charge of the battery.
•Multimeter will show one value between
13,5 and 15V.
If the battery doesn’t have the correct charge
level the electronics will not work correctly and
show an internal error code.
Once the battery is checked, and replaced if necessary, erase the error with the
OBD reader. Switch ON the bike and run it, if the Error appears other time
check point 2.
