INTRODUCTION TO EMISSIONS STANDARDS

  • Three of the primary motorcycle exhaust emissions under government regulation are Hydrocarbons (HC), Nitrogen Oxides (NOx) and Carbon Monoxide (CO) and are measured in mean grams per kilometre (g/km).
  • There are currently no EU regulatory standards for CO2 (Carbon Dioxide) emissions for motorcycles, however, entering Suzuki's WMTC fuel consumption figure for the Suzuki Inazuma GW250 (85.87 mpg) into an Online CO2 Calculator results in a CO2 emissions figure of 76.32 g/km (ie: CO2 g/km = 6554 / mpg).

EU EMISSIONS STANDARDS (HC, NOx, CO)

  • The current EU motorcycle exhaust emissions standards applicable to the Suzuki Inazuma GW250 motorcycle (2012 onwards) are highlighted in GREEN in the table below.

US EMISSIONS STANDARDS

  • In the United States, motorcycle exhaust emissions standards are managed by the Environmental Protection Agency (EPA).
  • The state of California has special dispensation to promulgate more stringent vehicle emissions standards and other states may choose to follow either the national or California standards.
  • EPA regulations went into effect for the 2006 model year (the first revision to nation-wide motorcycle emissions requirements in more than 25 years).
  • The US EPA motorcycle exhaust emissions standards applicable to the Suzuki Inazuma GW250 motorcycle (2012 onwards) are highlighted in PINK in the table below
  • Note that in the US EPA Exhaust Emissions Standards the NOx value is added to the HC value to give a combined limit.

Source: United States Environmental Protection Agency - Highway Motorcycles Exhaust Emission Standards
a Starting with the 2006 model year EPA re-defined Class I to include motorcycles with engines smaller than 50 cubic centimeters. These new previously unregulated vehicles are Class I-A, and the pre-existing Class I became Class I-B.
b This is an optional standard that allows manufacturers to average their emissions or transfer emission credits across classes.

INTRODUCTION TO DIAGNOSTIC TROUBLE CODES (DTC)

  • Most modern Suzuki motorcycles have a Fuel Injection system controlled by an ECM (Engine Control Module).
  • If the ECM detects a fault situation, it will log and store a 2-digit fault code (eg: 'C12') in its memory, an 'FI' symbol (indicating 'Fault Indicator' or 'Fuel Injection' problem) will be shown on the Instrument LCD Panel and the red 'FI' LED will illuminate around 3 seconds after the Ignition Switch has been turned to the 'ON' position.
  • This 2-digit fault code can be used to help fault-find on Suzuki motorcycles.

DTC FAULT INDICATIONS

  • If the 'FI' indication on the Instrument LCD Panel is flashing but the red 'FI' LED remains steadily illuminated then a 'Get-You-Home' mode will be enabled and you will be able to continue to ride your motorcycle home (or to a Suzuki dealer) so that the fault can be repaired.
  • If the 'FI' indication on the Instrument LCD Panel is steadily shown but the red 'FI' LED is flashing then the engine is NOT able to run and you will need to find another means of getting your motorcycle home.
  • The 2-digit fault code, also known as a Suzuki Diagnostic Trouble Code (DTC), can be read out (the code is shown in place of the Odometer reading on the Instrument LCD Panel) by connecting a 'Mode Select Switch' (Suzuki Part Number: 09930-82720) to the DTC socket and switching it to the 'ON' position.

DTC SOCKET

  • On the Suzuki Inazuma GW250, the DTC socket is situated behind the rear right-hand frame cover panel (below and to the right of the seat).
  • You will first need to disconnect the white DTC socket from the white DTC plug in the wiring harness.
  • Don't forget to reconnect the DTC socket to the DTC plug when you have finished fault-finding.

DTC DEALER MODE

  • Operating the 'Mode Select Switch' enables 'Dealer Mode' instead of the default 'User Mode'.
  • Note that in 'Dealer Mode', the red 'FI' LED will NOT be illuminated.

DIY 'MODE SELECT SWITCH'

  • A Suzuki 'Mode Select Switch' will cost you around £15 ($25) but (wearing polythene gloves) you can also enable 'Dealer Mode' by shorting 2 terminals together carefully in the DCM socket with a metal paper clip as shown in the photo below.
  • Make sure that you short the correct 2 terminals with the paper clip (the wires to the 2 terminals on the Suzuki Inazuma GW250 should be Light Blue and Black / White Stripe). If you are not sure of what you are doing, use a proper Suzuki 'Mode Select Switch'.
  • The engine will need to be run or cranked for at least 4 seconds before a fault will be detected by the ECM.
  • When all the fault codes have been displayed and recorded on a piece of paper, switch off the engine, remove the metal paper clip and reconnect the DTC socket to the wiring harness.

DTC CODES

  • Not all possible Diagnostic Trouble Codes (DTC) are used on every Suzuki motorcycle. The possible codes will depend on your particular Suzuki model. For the Suzuki Inazuma GW250, 19 different DTC codes are possible as shown in the table below.
  • Do not disconnect any wire coupler from the ECM, any battery terminal or remove the main fuse if you have a fault with your motorcycle as that may erase the fault code.
  • If more than one fault is detected by the ECM, the fault codes will be shown, one after another, every 2 seconds, in the order of lower number to higher number.

DTC FAULT RESOLVED

  • If there is no malfunction or the fault has been resolved then 'C00' will be shown on the Instrument LCD Panel after the Ignition Switch has been turned to the 'OFF' position and then to the 'ON' position as shown in the photo below.

THROTTLE POSITION SENSOR

  • The line shown to the left of the 'C00' code indicates the Throttle Position (TP) sensor position when the engine is warm and idling at 1300 - 1500 RPM. The correct position for the line is in the middle.
  • If the line is at the bottom, remove the left-hand front frame cover panel, loosen the two securing Torx T25H screws and turn the sensor VERY SLIGHTLY anti-clockwise to bring the line to the middle.
  • If the line is at the top, turn the sensor VERY SLIGHTLY clockwise to bring the line to the middle. Finally, re-tighten the two Torx T25H screws and replace the left-hand front frame cover panel.
  • Note that the two securing Torx T25H screws normally have a dab of paint to indicate if they have been tampered with.

HOW TO CLEAR THE DTC HISTORY

  • To clear the DTC history from the ECM memory you will need to click your mouse on the 'Clear' button on the PC software program window of the Suzuki Diagnosis System or SDS (found on CD-ROM, Suzuki Part Number: 99565-01010-028) while the motorcycle is connected to the SDS module (Suzuki Part Number: 09904-41010) or take it to your Suzuki dealer who will be able to do this for you.
