Toyota Yaris: Fuel Pump (for High Pressure) / Removal
REMOVAL
CAUTION / NOTICE / HINT
The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during fuel pump assembly removal/installation are shown below.
Necessary Procedures After Parts Removed/Installed/Replaced
| Replaced Part or Performed Procedure | Necessary Procedure | Effect/Inoperative Function when Necessary Procedure not Performed | Link |
| Fuel pump assembly (for high pressure side) | Inspection after repair | -
Poor idle, etc.
-
Engine start function, etc.
|
|
CAUTION:
-
Never perform work on fuel system components near any possible ignition sources.
-
Vaporized fuel could ignite, resulting in a serious accident.
-
Do not perform work on fuel system components without first disconnecting the cable from the negative (-) auxiliary battery terminal.
-
Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
NOTICE:
-
After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 120 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
-
This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.

HINT:
When the cable is disconnected/reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
-
Learning completes when vehicle is driven
| Effect/Inoperative Function When Necessary Procedures are not Performed | Necessary Procedures | Link |
| Lane tracing assist system | Drive the vehicle straight ahead at 35 km/h (22 mph) or more for 5 second or more. |
|
| Pre-collision system |
| Stop and start system | Drive the vehicle until stop and start control is permitted (approximately 5 to 60 minutes) |
|
-
Learning completes when vehicle is operated normally
| Effect/Inoperative Function When Necessary Procedures are not Performed | Necessary Procedures | Link |
| Power door lock control system | Perform door unlock operation with door control switch or electrical key transmitter sub-assembly switch. |
|
| Air conditioning system | After the ignition switch is turned to ON, the servo motor standard position is recognized. | - |
