CTB DO148, Quick Start User Manual, Page: 2 / 12

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.
4. 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 drop the CTB onto the OBD female end or to use
excessive force when connecting a scan tool, as the CTB 16 pin female DLC connector maybe
pushed in or broken. This is deemed to be operator abuse and is not a warrantable item.
Failure to observe these warnings may result in vehicle, CTB or scan tool damage or
incorrect test results.
