STEP 23. Check the wiring harness between joint
connector (2) A-15 (terminal 1) and relay box (fuse No. 20).
Q: Is the wiring harness between joint connector (2) A-15
(terminal 1) and relay box (fuse No. 20) in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Verify that
the fog lights illuminate normally.
INTERIOR LIGHT
GENERAL DESCRIPTION CONCERNING INTERIOR LIGHT
M1549021800140
The ECU related to the interior light function types
and various control functions are as follows.
Dome light control function
When the dome light switch is at the door position,
the ETACS-ECU controls the lighting of the dome
light as follows:
• When a door is opened to get on or get off the
vehicle with the ignition switch off, the dome light
lights up at a luminance of 100 percent. When a
door is closed, the dome light dims at a lumi-
nance of 65 percent, and goes off 30 seconds
later. However if the ignition switch is turned ON
or if all doors are locked while they are closed,
the dome light will go off at that point.
• When a door is opened with the ignition switch
ON, the dome light lights up at a luminance of
100 percent. When a door is closed, the dome
light goes off.
• When the ignition key is removed with all doors
closed, the dome light lights up at a luminance of
100 percent, and goes off 30 seconds later. How-
ever if the ignition key is inserted again or if all
doors are locked while the dome light is lighting,
the dome light will go off at that point.
• The dome light is flashed twice when door is
locked with keyless entry. When door is unlocked
with keyless entry, the dome light lights at a lumi-
nance of 100 percent, and goes off 15 seconds
later.
