MEMORY FUNCTION
CHU050201026S04
• The memory function stores malfunction information detected in the malfunction detection function. Once
malfunction information is stored, the memory will not be cleared even when the ignition switch is turned off
(LOCK position) or the malfunction is repaired.
• The stored memory (malfunction information) can be cleared using the WDS or equivalent, or by disconnecting
the negative battery cable.
