Drew Technologies CarDAQ-M J2534-1&2 Module, Quick Start Manual

2 

CarDAQ-M has been carefully designed and tested to comply with OBDII 
protocols, which are used on most 1996 and newer cars and light trucks sold in 
the USA. However, some vehicle models are not in full compliance with these 
protocols for various reasons. In addition, the computer control systems or 
sensors on any given vehicle may be malfunctioning or out of specification. 
 

Note:

 Vehicles manufactured for use outside of the USA may not comply with 

OBDII protocols, even though an SAE J1962 connector is located in the vehicle. 
Connection to vehicles manufactured for use outside of the USA is AT YOUR 
OWN RISK. Drew Technologies will not be held responsible for ANY direct, 
indirect or consequential damage that arises as a result of connecting to such a 
vehicle.  
 
Before installing CarDAQ-M, we recommend visiting this website for service

While Drew Technologies testing and the experience of thousands of CarDAQ-M 
users have shown the interface to be safe and reliable, there is an inherent risk in 
using any product that may potentially affect the operation or drive-ability of your 
vehicle. Drew Technologies will not be held responsible for ANY direct, indirect or 
consequential damage that arises as a result of using CarDAQ-M on a vehicle. 
 
If you are concerned about the operation of your vehicle at any time while using



If you are driving, pull off the roadway immediately or as soon as it is 
safe to do so.
