| Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM (w/ Canister Pump Module): DTC CHECK / CLEAR; 2019 - 2020 MY RAV4 [11/2018 - 08/2020] | ||
DTC CHECK / CLEAR
NOTICE:
When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and Freeze Frame Data recorded in normal mode are cleared. Before changing modes, always check and make a note of DTCs and Freeze Frame Data.
HINT:
- DTCs which are stored in the ECM can be displayed on the Techstream. The Techstream can display the confirmed, pending and permanent DTCs.
- If a malfunction is detected during the current driving cycle, confirmed and permanent DTCs are stored.
- Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
- confirmed and pending DTCs can be cleared by using the Techstream or by disconnecting the cable from the negative (-) battery terminal. However, permanent DTCs cannot be cleared using either of these two methods.
-
After clearing current DTCs using the Techstream (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.
To clear permanent DTCs, all of the following conditions must be are met:
- There is a history that universal trip driving was performed.
- The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)
- No malfunctions are detected.
2 Trip Detection Logic Examples
|
Pending DTC |
Store condition |
Malfunction detected |
|
Clear condition |
System determined to be normal or DTCs cleared using Techstream or Cable disconnected from negative (-) battery terminal |
|
|
Confirmed DTC |
Store condition |
Malfunction detected (2nd trip) |
|
Clear condition |
No malfunctions in 40 driving cycles or DTCs cleared using Techstream or Cable disconnected from negative (-) battery terminal |
|
|
Permanent DTC |
Store condition |
Malfunction detected (2nd trip) |
|
Clear condition |
Ignition switch turned to ON after normal judgment obtained in 3 consecutive driving cycles or After DTCs cleared using Techstream or cable disconnected from negative (-) battery terminal, universal trip performed and normal judgment obtained for 2 trips (not for misfire and fuel system DTCs) or After DTCs cleared using Techstream or cable disconnected from negative (-) battery terminal, malfunction not detected when universal trip driving performed (misfire and fuel system DTCs) |
|
|
MIL |
ON |
Malfunction detected (2nd trip) |
|
OFF |
Ignition switch turned to ON after normal judgment obtained in 3 consecutive driving cycles or DTCs cleared using Techstream or Cable disconnected from negative (-) battery terminal |
HINT:
- Obtaining a normal judgment and performing a universal trip driving pattern can be done in the same driving cycle or in different driving cycles.
- It is unnecessary to obtain a normal judgment if the output DTCs are misfire or fuel system DTCs.
CHECK DTC
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
Powertrain > Engine > Trouble Codes
(e) Check the DTC(s) and Freeze Frame Data, and then write them down.
|
Techstream Display |
Description |
|---|---|
|
Test Failed |
Shows the malfunction judgment results during the current trip. |
|
Pending |
Shows the malfunction judgment results up to now. (Indicates the possibility of a malfunction when no DTC is confirmed.) |
|
Confirmed |
Shows the DTCs confirmed up to now. (The number of current trips differs for each DTC.) |
(f) Check the details of the DTC(s).

CLEAR DTC (Pending and Confirmed DTC)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Clear the DTCs.
Powertrain > Engine > Clear DTCs
CLEAR DTC (Pending and Confirmed DTC without using Techstream)
(a) Perform either of the following operations:
NOTICE:
After turning 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.

(1) Disconnect the cable from the negative (-) battery terminal for more than 1 minute.
(2) Remove the EFI-MAIN NO. 4 fuse from the No. 1 engine room relay block and junction block assembly located inside the engine compartment for more than 1 minute.
OUTLINE
- After clearing current DTCs using the Techstream (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

To clear permanent DTCs, all of the following conditions must be are met:
- There is a history that universal trip driving was performed.
- The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)
- No malfunctions are detected.
CLEAR PERMANENT DTC

(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
Powertrain > Engine > Trouble Codes
HINT:
If "PERMANENT" in the top right of the screen displays "YES", permanent DTCs are stored.
(e) Select the "Generic" tab.
