CHECK CHART FOR DIAGNOSIS CODES


caution During diagnosis, a diagnosis code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for diagnosis code(s). If diagnosis code(s) are set, erase them all.
Code No.

note
  • *1: Electrically Erasable Programmable ROM
  • *2: This diagnosis code will remain in memory and the SRS warning lamp will be switched off when the system returns to normal condition.
  • *3: This diagnosis code cannot be erased by "Erase diagnosis codes" function.
  • *4: This front impact sensor (LH) indicates that the front impact sensor integrated in the centre of the vehicle is defective.
