Dtc check/clear
1. Dtc check (normal mode)
Notice:
hand–held tester only:
when the diagnostic system is switched from the normal
mode to the check mode, all the dtcs and freeze frame
data recorded in the normal mode will be erased. So before
switching modes, always check the dtcs and freeze frame
data, and ...

1 Check relay (marking: starter cut)
Inspect the relay continuity, as shown in the illustration
and table.
Standard:
2 Check tvip ecu
Disconnect the tvip ecu connector.
turn the ignition switch position to the start.
measure the voltage between the termina ...
