*1: No inspection required when ABS, TRC, VSC warning lamp ON (B5 terminal output 10~14V due to

warning output. Other terminal output 0V caused by solenoid relay OFF due to fail safe function).

*2: When normal, output 1ms cycle and 0.5ms serial signal pulse occurs.

*3: When normal, output 2ms cycle and 0.5ms serial signal pulse occurs.
