The scan tools rely on this power being present. No Voltage or Low Voltage on Connectorīy specification, every OBDII connector must have 12-v power on pin 16 and ground on pins 4 and 5. The scan tool may not connect to the OBDII system if you do not wait for the complete system boot-up. A good rule is to engage the scan tool after all chimes have finished and all dashboard activity has been completed. Also, many vehicles take several seconds for all of the modules to finish their boot-up sequences. Most OBDII scan tools require that the ignition key be placed in the run position, or the engine be running. These kind of manufafacturer specific protocols require a scan tool with a software that is capable of reading these PIDs. A professional multi-system diagnostic scanner with OBD1 OBD2 compatibility will be required to diagnose wider range of vehicles and systems. While most OBD code readers should be able to communicate with cars that use the standarised OBDII protocols - or cars with OBD2 compatible protocol to cover the engine/emission management system a common issue with communication can be that the car you are trying to connect uses a non standarised OBD protocol such as ALDL, MOBD, MUTT or OBD1 etc. Below we explain some of them with more details. In most cases, communication issues can be caused by various reasons including: ignition-key position, connector-voltage issues, incorrect communication protocol, hung ECM, missing or bad data, and OEM-updated ECM software that is unknown to the scan tool. In this article we will briefly explain some of the reasons and what can be done to troubleshoot any communication error between your OBD2 scanner and your car. With error message showing "No-Communication"! Using an OBD2 scan tool to communicate with vehicle's ECU is generally considered pretty straightforward task. However, on some rare occasions certain issues can make connection and communicating to the system troublesome.

For the newer ECU's he requires you to post a read out from the software so that he can send you a fully functioning version of the software (it is linked to the ECU serial number to prevent commercial use) for the older ECU's it works straight out of the box (including setting the TPS and resetting the service light). He has done some tweaks to the software and it now works with older 5.9M ECU's like the one fitted to my 2003 999. There is a full list of compatible bikes on the site. The attached link takes you to a French guy's site who has created a diagnostic software package for the 5.9AM ECU's.
