DIAGNOSIS SYSTEM (BCM)
ERASE SELF-DIAGNOSIS
With CONSULT-III
1. Perform applicable inspection of malfunctioning item and then repair or replace.
2. Turn ignition switch “ON” and select “SELF-DIAG
RESULTS” mode for “AIR PRESSURE MONITOR” with
CONSULTIII.
3. Touch “ERASE” on CONSULT-III screen to erase memory.
Without CONSULT-III
• In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned “ON” and“OFF”.
• However, this information is erased by turning igniti on switch “OFF” after performing self-diagnostic or by
erasing the memory using the CONSULT-III.
