Ah ok. Thanks. Don't think mine has that, sadly.
One more question regarding my current IS250 which some of you advised me on after my head gasket went bang at Xmas.
I've tried to reset the ECU tonight by disconnecting the battery to see if I can get rid of the damn warning lights that have been there since the engine swap.
First time I left it disconnected for 10 mins then reconnected and tried it. 100 yards down the road and Check VSC flashed up again along with engine warning light and TCS light. So I tried again, but this time left it for 1.5 hours.
Much better result! Managed to drive around town, down the motorway and back toward home, no sign of warning lights or message and fuel economy is way up on what it has been... Then I stopped at the shop... 100 yards down the road and Check VSC is back! 😡
Question is, how long does it take to reset the ECU this way? Both times my one-touch windows reset and my radio presets, but driving position settings only reset on the second try. But the Bluetooth phone connection remained on both times, so I'd hazard a guess that it's not fully resetting.
TL;DR? - basically, how long do I need to keep the battery disconnected in order to fully reset the ECU. Thanks.
