CIRCUIT OPERATION
The ETACS-ECU operates the dome lamp dimming
function according to the input signals from the fol-
lowing switches:
Ignition switch (IG1): OFF
Key reminder switch: ON
Door switches: OFF

Inspection Procedure K-1 "The dome lamp do not
illuminate and go out normally P.54B-359."
Some of the interior lamps do not illuminate normally. :
Refer to Inspection Procedure K-2 "The front dome
lamp, rear dome lamp or trunk lamp do not illuminate
or go out normally P.54B-366."
STEP 2. Check the adjustment function.
Q: Has a setting other than "No auto-shutoff" been
selected for the interior lamp automatic shutdown
function by the adjustment function?
YES : Go to Step 3.
NO : Set the interior lamp automatic shutdown function to
another setting other than "No auto-shutoff".
