Description
BCM
• Activates the interior room lamp timer depending on the vehicle condition to turn the
interior room lamp ON/OFF.
• Turns the step lamp ON /OFF according to any door switch status.
• Operates the interior room lamp battery saver depending on the vehicle condition to
cut the interior room lamp power supply.
• Detects each switch condition by the combination switch reading function.
• Judges the illumination lamp ON/OFF status depending on the vehicle condition.
And then it transmits position light request signal to IPDM E/R and combination
meter (with CAN communication).
IPDM E/R
Controls the integrated relay according to the request from BCM (with CAN communi-
cation).

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits position light request signal to IPDM E/R and combination meter according to tail lamp ON
condition.
Tail lamp ON condition
- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment
- Lighting switch AUTO, with the front fog lamp switch ON and the ignition switch ON
• IPDM E/R turns the integrated tail lamp relay ON according to position light request signal. It provides the
