Have you checked continuity between pin 34 on the meter and connector C228, pin 53 (Blue wire) on the ETACS ECU? Also, what happens if you earth pin 53?

ETACS ECU is faulty then.

If the other outputs (interior light and chime) are working as they should then the only option is the ECU.

You're still using the ETACS ECU though? It is separate from the engine ECU.

 

[jhfozzy]

Yes

 

[jhfozzy]

Yeah, no programming needed.
