Error Codes - OVMS User Manual

OVMS: Renault Twizy User Guide

Error codes

...will be shown as hexadecimal values. If an SDO cannot be read or written, the SDO index and
subindex will be indicated as well. Example:
ERROR 0020 SDO 0x5110.00: 0x0005
This means:
– Error code "0020" containing...
– ...error class "002x" = switching to pre-operational mode
– ...error detail (x) "0" = no low level error
– last accessed SDO was 0x5110.00 = current mode register
– value of SDO was 5 = "operational mode"
As there was no low level error, the pre-op mode switch was denied by the OVMS due to security
constraints (i.e. no pre-op mode while Twizy is in normal drive mode).
Error classes are:
– 001x = SEVCON login
– 002x = switching to pre-operational mode
– 003x = command parameter out of range (x = failed parameter number)
– 004x = unknown hardware
CAN I/O detail error codes (x) may be:
– 1 = No CAN bus write access (feature #15)
– 2..5 = SDO read errors
– 8..9 = SDO write errors
– A = Timeout
– B = Component offline
So for example a code "004B" means the OVMS cannot check the SEVCON type as it's offline.
If on a CAN error the SDO value is "0x08...", it's the CANopen abort code. See SEVCON manual
for a list of these.
CAN level errors are temporary, repeating the last command will normally succeed. If a state
change cannot be performed, try to switch the Twizy off and on again before repeating the
command. When switching on, do not continue to "GO". See above.
If an error persists or can be reproduced in a certain way, please post a complete description to the
OVMS forum or mailing list.
