INSPECTION PROCEDURE

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

.

HINT:

1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0606; ECM /...

Read freeze frame data using a Techstream. Freeze frame data record the engine condition when

malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other
data from the time the malfunction occurred.

PROCEDURE

1.

CHECK FOR DTC

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear DTCs

.

(e) Turn the ignition switch off and turn the Techstream off.

(f) Disconnect the Techstream.

(g) Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.

(h) Connect the cable to the negative (-) battery terminal.

(i) Connect the Techstream to the DLC3.

(j) Turn the ignition switch to ON.

(k) Turn the Techstream on.

(l) Wait for 16 seconds or more.
