BCM (BODY CONTROL MODULE)
 Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF is not to be fluctuated by being overloaded.
 Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT -III. Refer to
BCS-24, "
COMB SW : CONSULT-III Function (BCM - COMB SW)".
 BCM reads the status of the combination switch at 10 ms internal normally. Refer to BCS-7, "

DescriptionINFOID:0000000001722956
Light reminder warning does not sound even though headlamp is illuminated.
Diagnosis ProcedureINFOID:0000000001722957
1.CHECK COMBINATION SWITCH (LIGHTING SWITCH) OPERATION
Check that the headlamps operate normally by operating the combination switch (lighting switch).
Do they operate normally?
YES >> GO TO 2
NO >> Refer to EXL-5, "
Work Flow".
2.CHECK FRONT DOOR SWITCH (DRIVER SIDE) SIGNAL CIRCUIT
Perform inspection of the front door switch (driver side) signal circuit.

DRIVER SIDE : Diagnosis Procedure"
 With Intelligent Key and super lock: DLK-296, "DRIVER SIDE : Diagnosis Procedure"
 Without Intelligent Key and super lock: DLK-499, "DRIVER SIDE : Diagnosis Procedure"
 Without Intelligent Key, with super lock: DLK-644, "DRIVER SIDE : Diagnosis Procedure"
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
3.CHECK FRONT DOOR SWITCH (DRIVER SIDE)
Perform a unit inspection for the front door switch (driver side).
 With Intelligent Key, without super lock: DLK-66, "
DRIVER SIDE : Component Inspection"
 With Intelligent Key and super lock: DLK-297, "DRIVER SIDE : Component Inspection"
 Without Intelligent Key and super lock: DLK-500, "DRIVER SIDE : Component Inspection"
 Without Intelligent Key, with super lock: DLK-645, "DRIVER SIDE : Component Inspection"
Is the inspection result normal?

THE KEY WARNING DOES NOT SOUND
THE KEY WARNING DOES NOT SOUND
DescriptionINFOID:0000000001722960
Key warning does not sound even though key is in ignition and front door (driver side) is opened.
Diagnosis ProcedureINFOID:0000000001722961
1.CHECK WARNING CHIME OPERATION
With key removed from the ignition and the front door (driver side) open, turn the lighting switch to 1st or 2nd
position.
Does warning chime sound?
YES >> GO TO 2
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".

DiagnosisProcedure" (with Intelligent Key) or
WCS-28, "
DiagnosisProcedure" (without Intelligent Key).
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
3.CHECK KEY SWITCH
Perform a unit inspection for the key switch. Refer to WCS-27, "
Component Inspection" (with Intelligent Key)
or WCS-29, "
Component Inspection" (without Intelligent Key).
Is the inspection result normal?
