ISO activity for Motorcycle OBD connector
ISO/TC22/SC38/WG4
presentation at 9th L-EPPR
Geneve, 12 January 2015

2. ISO/TC22/SC38/WG4

3. Members of SC38/WG4
Convenor: Koji Yamada (Suzuki) Secretary: Ayako Tsukiyama (JSAE) Active Experts from: JAPAN, ITALY, US

4. Workplan of SC38/WG4 1. In June 2013 (Pontedera, IT)
WG17 (Pollution and Energy) agreed to establish an OBD connector standard for motorcycles/mopeds exclusively.
2. In Oct 2013 (Vienna, A)
SC38 agreed to organize a new WG dealing with the standardization activity for a Motorcycle dedicated OBD connector.
3. In March 2014
A New Work Item Proposal (NWIP) was officially approved by P-members.

5. Workplan of SC38/WG4 4. In May 2014 (Turin, IT)
The Kick-of meeting was held, agreeing the following:
-- target and timeline of WG4,
-- to define "one type of connector with 6 pins" in the standard,
-- to go with a faster process (skipping WD stage and FDIS stage),
5. In Nov 2014 (Kyoto, JP)
The 2nd meeting of WG4 was held, agreeing to submit the draft as CD.
The next 3rd meeting is scheduled in Rome (IT) in May 2015.

6. Target of SC38/WG4 Why we are not using ISO 15031-3 connector
The existing OBD standards such as ISO15031 are for passenger cars.
ISO is especially not applicable for motorcycles/mopeds since a connector for motorcycle/moped needs to satisfy specific requirements such as water-proofness and smaller size.
Target of SC38/WG4
To define the ISO standard for a motorcycle/moped dedicated OBD
connector:
- meeting specific requirement for motorcycle/mopeds
(waterproof, suitable size, optimized contacts, accessibility & anti-chemical fluid)
- based on ISO for commonality and productivity

7. Target of SC38/WG4
Target of WG4 is to standardize for; 1. Waterproof 2. Suitable size 3. Optimized contacts 4. Accessibility 5. Anti-chemical fluids

8. Target of SC38/WG4 1. Waterproof
Motorcycle does not have a watertight compartment.
5.7.4 Connector system performance requirements
The connector system shall meet the performance requirements given in a) to e) of this sub clause, following performance of each of the environmental exposures according to Measurements shall be taken at room temperature (23°C ± 5°C).
Insulation resistance between adjacent contacts tested in accordance with ISO :2005, 4.12:≧ 100 MΩ.
Contact retention in housing tested in accordance with ISO :2005, 4.7: ≧ 60 N.
Connection and disconnection force tested in accordance with ISO :2005, 4.3.1, fully equipped with 6 contact pairs: ≦ 75 N.
Polarization features shall prevent mismating of connectors when a force of 150 N is applied.
Waterproofness tested in accordance with ISO :2005, : leakage current≦ 50μA at 48V and ,
Extracted from ISO CD
Define waterproof toughness according to ISO

9. Target of SC38/WG4 2. Suitable size
Car connector is not of a suitable size for compact motorcycles/mopeds
Car connector
New OBD connector for motorcycle
Design new OBD connector 3 times smaller than car connector

10. Target of SC38/WG4 3. Optimized contacts
Only 6 pins are necessary/enough for motorcycles/mopeds.
Eliminate unnecessary pins for motorcycle from car connector

11. Extracted from EU regulation
Target of SC38/WG4
4. Accessibility
The connector shall meet the requirements for position/ accessibility/protection defined by EU regulation No.44/2014.
(3.12)
The preferred installation position is under the seating position. Any other position of the diagnostic connector shall be subject to the approval authority’s agreement and be readily accessible by service personnel but protected from tampering by non-qualified personnel.
Extracted from EU regulation
Smaller connector is necessary for limited space in motorcycle to meet requirement of EU Regulation N. 44/2014

12. Target of SC38/WG4 5. Anti-chemical fluids
The connector for motorcycle could be influenced by chemical fluids such as engine oil, brake fluid, and engine coolant, etc.
(4.23) Chemical fluids
(4.23.1) Principle and application
The resistance to chemical fluids is only required for connectors likely to be exposed to such fluids. For this purpose, a list of chemicals and tests common to automotive use has been established (see Table 7). The vehicle manufacturer and supplier should choose the fluids and tests depending on the connector application.
Extracted from ISO
