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 identifi-
cation plate. Refer to GI-41, "IDENTIFICATION PLATE".
●*1: These numbers are prescribed by ISO 15031-5.
●*2: When the fail-safe operation occurs, the MI illuminates.
●*3: The MI 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
