The two TPU inputs that the CANdi module requires are TPU12 and TPU15, which enable the module<br />
and detect its presence. If TPU12 and 15 do not appear on the screen, then they are defective in the<br />
VCI module and the VCI is failing to properly enable the CANdi module. If the above test passes, you<br />
must repeat the same test with the Burndy loopback adapter at the end of the cable. The setup is the<br />
same as if you were plugging into a vehicle without the CANdi module connected and with the loopback<br />
adapter at the end of the cable. Then you must run the VCI TPU test. If the example above appears<br />
(TPU13 and 14 are missing in this test because these I/Os don’t go through the cable), then the cable<br />
is also fine. However, if TPU12 and 15 are missing, then the cable is defective.<br />
4. Verify that the DLC cable (also known as the ALDL, J-1962, or OBDII interface cable) is functioning<br />
properly and then proceed to step five. Replace the DLC cable if it does not function properly. Call the<br />
<strong>Tech</strong>line Customer Support Center (TCSC) at 1-800-828-6860 for more information if you have trouble<br />
with this test.<br />
