For those Altezza that's with sunroof.
Do u know that the sunroof can be 'set' & 'reinitialize' ?? lol...
below are excepted from Australia tezza forums. (well, not sure is for IS200 or Altezza, but is good tips)
The service manual says the following about the sunroof, this is a straight copy paste - hope it helps...
"Sliding roof always re-opens (anti trap function)"
Increase the foce by running the sliding roof again manually by pushing and holding the close switch within
10 sec.( Try max 3 times )
When the sliding roof starts reversing ( Resistance becomes greater due to the deformation of seal.),
press the switch and hold it. So reverse force increases, then the sliding roof can be closed.
First time : Reverse with force of 100N
Second time : Reverse with force of 150N
Third time : No jam protection function
* Press the switch within 10 seconds after the roof has started reversing.
Otherwise, sliding roof ECU returns to the un initialized condition.
If this fails it recommends trying...
*Reinitialize
When the sliding roof does not stop at the normal position, ever
though the above operations have been performed, resetting is necessary.\
*Reinitializing method
(a) Move the sliding roof to the maximum tilted position.
( Release the switch, press the switch again and hold it for 10 secs.
© The sliding roof operates in a cycle of TILT DOWN " SLIDE OPEN " SLIDE CLOSE " TILT UP.
This completes reinitializing.
i didn't know that its circuit is intelligent!
