CAUTION / NOTICE / HINT
The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during cylinder head gasket removal/installation are shown below.
| Replaced Part or Performed Procedure | Necessary Procedure | Effect/Inoperative Function when Necessary Procedure not Performed | Link |
|---|---|---|---|
|
*: Even when not replacing the part, it is necessary to perform the specified necessary procedures afterinstallation. *1: Also necessary after performing a tire rotation. *2: It is not necessary to perform this procedure if the tire pressure warning valve and transmitters areinstalled to the same location. *3: When the starter assembly is replaced, "ST relay" must be also replaced. *4: The vehicle height changes because of suspension or tire replacement. *5: If transaxle compensation code read from ECM *6: If transaxle compensation code not read from ECM |
