Assuming that the replacement VVEL module is good, I would focus on the wiring. Verify the module has 12v on pin 1, 8 and 13 with ignition on, engine off.

Pins 11 and 24 are the dedicated CAN bus that runs from the ECU to the VVEL module. • With the battery disconnected, the resistance between pins 11 and 24 should be around 60 ohms. This verifies the CAN bus wires and proper bus termination. • With the battery connected and engine running, check the voltage between pin 11 + 14 (ground) and pin 24 + 14 (ground) You should see around 2.2V for CAN-Low and 2.7V for CAN-High. |
