homelink 3* |
Abort Long pre conditioning, it will also aborted if you unlock your Zoe. |
(* Requires V-CAN connection)
CAN security gateway & OBD port limitations
The Renault Zoe Phase 2 has a CAN security gateway, making the OBD port normally silent. All OVMS metrics must be polled through UDS/ISO-TP, similar to OEM diagnostic software. The CAN gateway forwards these polls to the appropriate ECU.
OVMS cannot determine if the vehicle is awake unless polling is actively triggered.
Continuous polling drains the 12V battery.
Due to CAN security restrictions, commands cannot be sent via OBD port. A V-CAN connection is required for remote control functions.
The vehicle’s Telematics Control Unit (TCU) requests battery statistics from the BMS, allowing OVMS to detect wake-up events.
If you want to disable or remove the TCU a V-CAN connection is absolutely neccessary.
V-CAN connection
The primary vehicle CAN (V-CAN) connects critical ECUs such as BCM, HVAC, Instrument Cluster and more. It can be connected to the OVMS module instead of OBD port connection.
A V-CAN connection enables:
Accurate wake-up detection (without relying on the TCU).
Additional control functions (e.g., pre-climate control, unlocking).
Metrics like Dashboard-SOC, Charge time remaining and estimated range (grabbed from Zoes ECUs instead of calculation within OVMS)
BMS firmware recommendation
If your BMS firmware is 530 or lower, enable “OVMS Energy Calculation” in the setup menu. Older firmware versions miscalculate energy values, leading to an accelerated SoH decline and extended “0 km range” driving.
For an upgrade, visit a Renault dealer with CLIP and Token access. Ensure “COMPUTER DATA” is not rewritten after flashing to prevent issues.
