Hi guys, i got problem with my sport mode. When i'm driving in D, the sport mode keep on and off every 2 second. I have already diagnose with GT1 but no fault code appear. Do u guys have any idea what is the prob? my machanic suspect the gearbox's ecu that cause the prob.. thanx

I am just guessing but here goes...

It could be the gearlever shifter mechanism.
When u push it to the left, it goes to 'S' mode.
Therefore, if on 'D' mode, and u experience it changing to 'S' mode, it could mean there's something wrong with the switch component etc.
This kind of defect would not be picked up by GT1 as it is interpreted as intensional switching....
Check it out la....

Just change gear position switch. But stil not solve the problem but "sport mode" not appear often as it used to be.
