KEY SWITCH SIGNAL CIRCUIT (WITH INTELLIGENT KEY)
DescriptionINFOID:0000000001722936
Transmits a key switch signal to the BCM.
Component Function CheckINFOID:0000000001722937
1.CHECK BCM INPUT SIGNAL
Select “DATA MONITOR” for “BCM” and check the “KEY IN SW” monitor value.
>> Inspection End.
Diagnosis ProcedureINFOID:0000000001722938
1.CHECK FUSE
Check if the key switch and ignition knob switch 10A fuse (No. 31, located in the fuse and relay box) is blown.
