Check CAN communication waveform generation
WARNING: This page is about a different variant/trim than selected.
- IG "OFF" and connect each channel scope to P-CAN HIGH terminal and P-CAN LOW terminal.
- IG "ON" after disconnecting each module that included in P-CAN network.
Specification: At Ignition "ON", the waveform is same as the one of "Signal Waveform & Data".
* Different from "Signal Waveform & Data", if 1) both CAN HIGH and LOW signal are fixed at 2.5 V or 2) HIGH and LOW signal are fixed at 3.5 V and 1.5 V, respectively, it is due to communication error between modules.
- Is the measured waveform normal?
YES
- Fault is intermittent caused by poor contact, and go to "VERIFICATION OF VEHICLE REPAIR ".
NO
- Replace the module which generates poor communication waveform, and go to "VERIFICATION OF VEHICLE REPAIR ".
