< FUNCTION DIAGNOSIS >

DIAGNOSIS SYSTEM (BCM)

The BCM records the following condition at the moment a particular DTC is detected.
• Vehicle Speed
• Odd Trip Meter
• 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.
