BCM (BODY CONTROL MODULE)
HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

SYMPTOM DIAGNOSIS
THE PARKING BRAKE RELEASE WARNING CONTINUES SOUNDING, OR
DOES NOT SOUND
DescriptionINFOID:0000000003838721
 The parking brake warning buzzer sounds continuously during vehicle travel though the parking brake is
released
 The parking brake warning buzzer does not sound at all even though driving the vehicle with the parking
brake applied.
Diagnosis ProcedureINFOID:0000000003838722
1.CHECK PARKING BRAKE WARNING LAMP
1. Start the engine.
2. Check the operation of the brake warning lamp by operating the parking brake.
Is the inspection result normal?
YES >> Replace the combination meter.
NO >> GO TO 2.
2.CHECK PARKING BRAKE SWITCH SIGNAL CIRCUIT
Perform a check for the parking brake switch signal circuit. Refer to MWI-52, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK PARKING BRAKE SWITCH UNIT
Perform a unit check for the parking brake switch. Refer to BRC-124, "
Component Inspection".
Is the inspection result normal?
YES >> Replace the combination meter.
NO >> Replace the parking brake switch.
When parking brake is applied : ON
When parking brake is released : OFF
