6. CHECK ENGINE BRAKE
Check engine brake.
Does vehicle decelerate by engine brake?
YES >> 1. Stop vehicle.
2. Perform self-diagnosis. Refer to AT-82, "
SELF-DIAG-
NOSTIC RESULT MODE" , AT-90, "Diagnostic Proce-
dure Without CONSULT-II" .
NO >>

Mark the box on the AT-47, "DIAGNOSTIC WORK-
SHEET" .

Go to AT-223, "Vehicle Does Not Decelerate by
Engine Brake" .

Stop “Road Test”.
