TROUBLE DIAGNOSIS — INDEX
P NO. INDEX FOR DTC
Check if the vehicle is a model with Euro-OBD system or not by the “Type approval number” on the identifica-
tion plate. Refer to GI-43, "
IDENTIFICATION PLATE" .
●*1: These numbers are prescribed by SAE J2012.
●*2: When the fail-safe operation occurs, the MIL illuminates.
●*3: The MIL illuminates when both the “Revolution sensor signal” and the “Vehicle speed sensor signal” meet the fail-safe condition at
the same time.Type approval number Model
