B2555 STOP LAMP

B2555 STOP LAMP

Description

INFOID:0000000009950126

BCM detects the stop lamp status and confirms the stop lamp switch ON/OFF status. BCM confirms the
engine start condition according to the stop lamp switch ON/OFF status.

DTC Logic

INFOID:0000000009950127

STOP LAMP

BCM makes a comparison between the 
upper voltage and lower voltage of stop 
lamp switch. It judges from their values to 
detect the malfunctioning circuit.

• Harness or connectors

(Stop lamp switch circuit is open or shorted)

• Stop lamp switch
• Fuse
