INSPECTION PROCEDURE
HINT:

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at
the time of the malfunction.
1 READ VALUE OF HAND±HELD TESTER(INTAKE MANIFOLD ABSOLUTE
PRESSURE)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Push the hand±held tester main switch ON.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / MAPº and read its value displayed on
the hand±held tester.

HINT:
When each warning light stays blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal
ground short in each ECU is suspected.
