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. Make sure to use the ground on pin 14.
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.
