1. Box This is necessary as a scan tool may be needed to log on as a communication node of the CAN Bus system Without scan tool recognition the system will not transmit signal data to the CTB and therefore connection of the CTB may result in failure of the CTB interface LEDs to operate when performing a diagnosis 11 15 11 20112. capture SB can Test Box CTB Scan Tool and Oscilloscope Connections Vehicle DLC im 10 CAN Test Box Connection Schematic PC USB Connection Automotive Oscilloscope CAN Low u 5 5 0 50 2 5 5 u 5 5 2 u T A I Signal Ground a uU 5 5 5 5 5 5 5 5 5 UU u I Scan Tool Connection WARNING Observe workshop safety practices 5 11183 can Test Box OBD II Connector Pin Designation OBD II Connector Note IS09141 2 amp ISO 14230 keyword 2000 use the same pinout so you cannot distinguish between the two by simply examining the connector Connect and use the CTB Monitor the LED indicators for protocols activity to identify the network structure in use CTB and CAN Bus system diagnostics Manufacturer s Proprietary Bus Line of J1850 Manufacturer s Proprietary Chassis Ground 1 2 3 4 5 Signal Ground 6 CAN High of SAE of J2284 7 K Line of IS09141 2 amp keyword 2000 8 Manufacturer s Proprietary 9 Manufacturer s Proprietary 10 Bus Line of SAE J1850 11 Clock Proprietary 12 Manufacturer s Proprietary 13 Manufacturer s Proprietary 14 CAN Low of SAE J2284 15 L Line of ISO 9141 2 amp keyword 2000 16 Battery Power 4 amp max Please note Some vehicles may require connection of a scan tool prior to connecting the CAN Test

4. Quick Start NOTICE 1 Important As active LED signals may have the potential to interfere with CAN data package signals we do not recommend the CTB be connected to late model C A N protocol vehicles under the following conditions i With a scan tool attached whilst driving the vehicle during or under road test conditions ii CTB left connected to the vehicle DLC OBDII connector while road testing or left connected to the vehicle for extended periods of time 2 Important Only use external test devices such as probes oscilloscopes or diagnostic equipment with more than 1 megaohm of input impedance 3 Important Do not connect the CTB when performing any vehicle re flash or reprogramming procedures with scan tool or pass thru programming devices connected Failure to observe this can cause control module failure or damage Important Do not use the CTB to power any external test devices in excess of 1 2 amps 5 Important Use caution at all times when probing the 16 pin DLC breakout box Bridging pins e g pin 16 POWER to any other pin could result in serious vehicle electrical or computer damage 6 Important The working and operating voltage of the CTB is 12 V to 15 V DC Under no circumstances should the CTB be used on any vehicle which has a higher operating voltage or the CTB unit will be permanently damaged For example it cannot be used on 24 V commercial vehicles 7 Important Care should be taken not to d
