Mode $09 – Reports vehicle information. This information
includes VIN number and calibration information stored in the
vehicle ECUs.
Mode $0A – Requests emission-related DTCs with permanent
status. This mode is required for all emissions-related DTCs. The
presence of permanent DTCs at an inspection without the MIL
illuminated is an indication that a proper repair was not verified by
the on-board monitoring system.
2.2 Oil Service Reset Review
The Engine Oil Life System calculates when to change the engine oil
and filter based on vehicle use. An oil change is required whenever
indicated by the display or according to the recommended
maintenance schedule. Whenever the oil is changed, reset the system
so it can calculate when the next oil change is required. If you
change the oil prior to a service indicator being turned on, please also
reset the system.
2.3 EPB Review
The EPB is a system which controls the brake force by pulling the
parking cable as in conventional existing parking brakes. EPB
system includes a DC motor, a gearbox, a screw, a nut, a current
sensor, a Hall-effect force sensor, an acceleration sensor and an
ECU.
Generally, if a driver or a high level system operates the EPB system,
the controller calculates a target force from the parking cable based
on the car mass as well as the inclination of the road as measured by
the acceleration sensor. The EPB increases the brake force by pulling
the parking cable using the DC motor until the brake force reaches
the target force. Brake force is measured by the Hall-effect force
sensor.
