OUTLINE
Each illumination lamp is controlled by each function of BCM and IPDM E/R.
Control by BCM Combination switch reading function
 Headlamp control function
Control by IPDM E/R Relay control function
ILLUMINATION CONTROL
 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 (With auto light system)
 IPDM E/R turns the integrated tail lamp relay ON according to position light request signal. It provides the
power supply to each illumination lamp.
 Combination meter dims the meter illumination according to position light request signal.

Part Description
BCM 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/RControls the integrated relay according to the request from BCM (with CAN communi-
cation).
Combination meterIlluminates the meter illumination according to the request signal from BCM (with CAN
communication).

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

Check that the following fuse and fusible link are not blown.
Is the fuse fusing?
YES >> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is
blown.
NO >> GO TO 2.
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connectors.
3. Check voltage between BCM harness connector and ground.
Is the measurement value normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
Does continuity exist?
YES >> INSPECTION END
