2019 - 2020 MY Corolla Corolla Hatchback [06/2018 - 09/2019]; M20A-FKS (ENGINE CONTROL): SFI SYSTEM: INITIALIZATION

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 (-) 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 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System (for Gasoline Model))
  • After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)

HINT:

If a malfunction such as pump lock occurs and the fuel pump is damaged, excessive current may be continuously applied to the fuel pump control ECU, damaging its internal parts. Make sure to replace the fuel pump control ECU at the same time when replacing the fuel pump.

PROCEDURE

1. PRECAUTION

NOTICE:

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

Pull off

NOTICE:

  • Remove any foreign matter on the fuel tube joint before performing this work.
  • Do not scratch or allow any foreign matter to get on the parts when disconnecting them as the fuel tube connector has O-rings that seal the pipe (fuel pipe).
  • Be sure to disconnect the fuel tube joint by hand.
  • Do not bend, twist, pinch or kink the nylon tube.
  • Cover the disconnected fuel tube joint with a plastic bag to prevent damage and contamination.
  • If the fuel tube joint and fuel suction plate sub-assembly are stuck, push and pull to release them.

9. REMOVE FUEL PUMP GAUGE RETAINER

(a) Remove the fuel pump gauge retainer.

(1) Temporarily install SST (plate) and SST (claw) to the fuel pump gauge retainer.

SST: 09808-01071

SST: 09808-14031

09808-01030

09808-01090

HINT:

Securely insert the ends of SST (claw) into the insertion points in the fuel pump gauge retainer.

(2) While firmly pressing SST (claw) into the insertion points in the fuel pump gauge retainer, tighten SST (bolt).

(3) Install SST (handle) and an extension bar (270 mm) to SST (plate).

SST: 09808-01071

*e

Extension Bar (270 mm)

(4) Lightly press down on SST to prevent it from separating from the fuel pump gauge retainer. While pressing down on SST, rotate SST (handle) slowly to loosen the fuel pump gauge retainer.

NOTICE:

  • Do not use any tools other than specified in this operation as this may result in damage to the fuel pump gauge retainer or the fuel tank assembly.
  • Do not press down on SST excessively as this may make the fuel pump gauge retainer hard to rotate, and may damage components.
  • Make sure to rotate SST (handle) horizontally. If it is rotated at an angle, SST may come off.
  • Do not spin SST too fast or use an impact wrench as this may result in damage to components.
  • If SST comes off of the fuel pump gauge retainer, loosen SST (bolt) and reinstall SST.

(5) While pressing down on the fuel suction tube with pump and gauge assembly, remove the fuel pump gauge retainer.

10. REMOVE FUEL SUCTION TUBE WITH PUMP AND GAUGE ASSEMBLY

(a) Remove the fuel suction tube with pump and gauge assembly from the fuel tank assembly.

NOTICE:

Be careful not to bend the arm of the fuel sender gauge assembly.

(b) Remove the fuel suction tube set gasket from the fuel tank assembly.
