52B-DIAGNOSTIC TROUBLE CODE CHART

CHECK CHART FOR DIAGNOSTIC TROUBLE CODES

caution

During diagnosis, a diagnostic trouble code associated with another system may be stored when the ignition switch is turned on with connector(s) disconnected. After completing the repair, confirm all systems for diagnostic trouble code(s). If diagnostic trouble code(s) are stored, erase them all.

Inspect according to the inspection chart that is appropriate for the DTC.

note

^*1: Electrically Erasable Programmable ROM
^*2: This diagnostic trouble code will remain in memory and the SRS warning light will be switched on even if the system returns to normal condition.
^*3: This diagnostic trouble code will remain in memory and the SRS warning light will be switched off when the system returns to normal condition.
^*4: This diagnostic trouble code cannot be erased by "Erase diagnostic trouble codes" function.
^*5: Though the SRS does not have emergency call function, this diagnostic trouble code is stored.
