Don't suppose anyone knows the difference between the round rain sensors, as fitted to corsa's, meriva B's, zafiras and some other vauxhalls,
They have a 2 letter code on them, SA, SB, SC and SD.
On ebay it seems the SD one is for the meriva B, i know the SC one is for corsa's, as i got one from a corsa at the scrappers,
I've wired it in... power and earth taken from the supply to the auto dipping mirror i fitted a few weeks ago (takne from the relevent pins on the BCM as if it were factory fitted),
and the data line to pin 20, plug X1 on the BCM.
I changed the variant programming in the BCM and the IPC to show rain/light sensor present, and the infrared led's in the ring of the sensor light up (seen via my phone camera.. and cameras see infrared) the led's only illuminate when pin 3.. data is connected to the sensor... and i checked globaltis and corsa's use the same sensor pin assignments.. 1 power, 2 earth, 3 data.
But it's not doing the sensign thing.. and tech2 says sensor malfunction.... i'm wondering if i have a duff sensor, or it really must be the SD variant for my car...
Don't suppose anyone has a SD variant sensor to sell me?
Also, if i fit the auto light switch, will i get auto lights? or is there another sensor used for that.. in tech2 i see 'tunnel detection' and i've read some cars use the sun strength sensor in the little nipple on the dash, which i dont have (i will have it when i change the heater unit over to full auto/dual zone, but thats a big project for much later.
