DIAGNOSTICS
ENGINE
1996 LAND CRUISER (RM451U)
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand
−
held tester) to check the DTC, use
normal mode. For codes on the DTC chart subject to ”2 trip
detection logic”, turn the ignition switch OFF after the
symptom is simulated the first time. Then repeat the simu-
lation process again. When the problem has been simu-
lated twice, the MIL lights up and the DTCs are recorded in
the ECM.
