Are you supposed to hold the button in for seven seconds after the every code individually? or after the entire sequence of codes has completed?

. . . by bringing up each fault and within 10 secs, hold the button down for 8 - 9 secs for each fault.

6. Idle Speed faulty <-- no adjustment for this!

9. Intake air temp sensor. Open or short. <-- is it connected? Many times the connector is left off when working on the car.

17. Data Exchange fault between individual control module. <-- #6 and this fault MAY be the start of a bad ETA (my page, MENU#24).

26. Upshift delay switchover valve, circuit open or short. <--- maybe a bad vacuum line to the transmission.
