Toyota do NOT check any cars ECU during its mandatory 9 month service.
Faults that can be found with a simple ECU test are missed.
Toyota did NOT respond to an email asking about their policy on WHY they
did NOT include an ECU scan of cars during a service. One employee
stated the only time they do an ECU scan is when the engine light comes
on. I am guessing YOUR car warranty would have well expired by then. A
very nice way to ensure there service department profits from a very
poor policy at your expense.
After inspecting 4 cars, 3 had a number of faults found during the ECU
scan. The faults I found were - ABS-VSC-TRC(CAN), Main Body?, U1 201 /
C1 294 / C1 249 refer to vehicle service manual, Engine and ECT,
Startability malfunction, Malfunction in Yaw Sensor, Air Conditioner,
Air Purifier Open Circuit. The last car came back ECU fault free.
I don't know if the above are major faults, only that three owners where
NOT happy learning that the faults were there and NOT sorted at time of
Service. After all isn't a service supposed to give you piece of mind
that the vehicles are in good condition. Why have a load of sensors in
your vehicle at all?
Toyota are unable to provide a print out of an ECU scan because they do
NOT have a printer connected to their test equipment? All you get if you
ask for a test is there word your car is fine?
Car accidents also VOIDS some warranties at Toyota discretion.
Weather its Toyota or any other car company, demand an ECU test during
your warranty service. I know of at least one other major brand who
actually provide a print out of an ECU test as part of their service plan.
Feel free to tell others of what I feel is very poor service to its
loyal customers.
