

If there is any malfunction, adjust the applicable part.

2. Park the vehicle on level ground.

3. Turn the ignition switch off.

4. Connect the M-MDS to the DLC-2.

WARNING:



Unless the initialization procedure of the combined sensor is
completed, the DSC will not operate, causing an unexpected
accident. Therefore, always perform the initialization procedure to
ensure DSC operation if the combined sensor and DSC HU/CM have
been removed or replaced.
