A2 VERIFY THE COMPUTERS AND CONTROL SYSTEMS INFORMATION PINPOINT TEST QA HAS BEEN CARRIED OUT
-
Verify that pinpoint test QA has been carried out.
-
Has pinpoint test QA been carried out?
Yes
GO to A3.
No
REFER to Computers and Control Systems Information, Pinpoint Tests, pinpoint test QA (gasoline engine) or AE (diesel engine) to diagnose no
