ERASE SELF-DIAGNOSIS

●

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 ignition switch “OFF” after performing self-diagnostics or by
erasing the memory using the CONSULT-II. Refer to

WT-23, "How to Erase Self-diagnostic Results"

ID Registration Procedure

With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press and hold the button for 5 seconds.

●

When ignition switch ON, and then low tire pressure warning
lamp blinks as per the following diagram, the respective then
