CHECK MODE PROCEDURE

1. DESCRIPTION

(a) Check mode has a higher sensitivity to malfunctions and can detect malfunctions that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect. In check mode, DTCs are detected with 1 trip detection logic.

2. CHECK MODE PROCEDURE

(a) Make sure that the following conditions are met:

(1) Battery positive voltage 11 V or higher.

(2) Throttle valve fully closed.

(3) Shift lever in P or N.

(4) Air conditioning off.
