1. Check the No. 15 (10 A) fuse in the under-hood fuse/relay box and the No. 5 (7.5 A) fuse in the driver's under-dash fuse/relay box. If the fuse is blown, find and correct the cause, then replace the fuse.

1. Turn the ceiling light switch in ‘‘DOOR'' (middle) position. Close all doors. Turn the ignition switch to ON (II).
   NOTE: If the driver's seat belt is unbuckled, the beeper will beep.

1. Connect the MPCS short connector (A) to the MICU service check connector (B), and turn the switch (C) on.

1. After 5 seconds, the ceiling light and ignition key light should come on for 2 seconds, go out, then blink once for 0.2 second. This means that you are in Test Mode 1 of the self-diagnostic function.

1. About 1 second after step 5, the ceiling light and ignition key light will blink and indicate the DTC, and repeat it every 3 seconds. If there is more than one DTC, the system will indicate them in ascending order, beginning from the DTC with the lowest numerical value.
