(1) Disconnect the fuse EFI (1 5 A) for 10 sec. or more, with iG switch OFF.
(2) Initiate test mode (Connect terminal TE2 and E 1 of DLC 1) with IG switch OFF.
(3) Start the engine and warm the engine up with all ACC switch OFF. .
(4) After the engine is warmed up, let it idle for 3 min.
(5)Accelerate gradually and maintain at approximately 1, 500 rpm, or within the 1, 300 to 1,700
rpm range. Turn the A/C on, and drive in ”D” for AIT, or in case of M/T, upshift appropri–
ately shift carefully so that the engine speed would not fall below 1,200 rpm. depress the
accelerator pedal gradually and maintain a steady speed to avoid engine braking.
(6) Maintain the vehicle speed at 40 – 50 mph.
Keep the vehicle running for 1 – 2 min. after starting acceleration.

HINT: If a malfunction is detected the malfunction indication lamp will light up during step(6) .

NOTICE: If the conditions in this test are not strictly followed, detection of the malfunction
will not be possible.

DIAGNOSTIC TROUBLE CODE DETECTION DRIVING PATTERN

Purpose of the driving pattern.
(a) To simulate diagnostic trouble code detecting condition after diagnostic trouble code is recorded.
(b) To check that the malfunction is corrected when the repair is completed confirming that diagnostic

trouble code is no longer detected.
