1. WARM UP ENGINE

Allow the engine to warm up to normal operating temperature.

2. CONNECT TOYOTA HAND-HELD TESTER OR OBDII SCAN TOOL

Diagram: A TOYOTA Hand-Held Tester connected to the DLC3 (Data Link Connector 3).

(a) Connect the TOYOTA hand-held tester or OBDII scan tool to the DLC3.

(b) Please refer to the TOYOTA hand-held tester or OBDII scan tool operator's manual for further details.

3. CHECK IGNITION TIMING

Diagram: Using a Special Service Tool (SST) to connect terminals TE1 and E1 of the DLC1 (Data Link Connector 1).

(a) Using SST, connect terminals TE1 and E1 of the DLC1.

SST: 09843-18020

HINT: After engine speed is kept at about 1,000 rpm for 5 seconds, check that it returns to idle speed.

Diagram: A timing light connected to the No.1 high-tension cord, pointing towards the engine's crankshaft pulley where timing marks are located.

(b) Using a timing light, connect the test probe to the No.1 high-tension cord.

(c) Check ignition timing.

Ignition timing: 3 - 7° BTDC @ idle

(d) Remove the SST from the DLC1.

SST: 09843-18020

4. FURTHER CHECK IGNITION TIMING

Ignition timing: 4 - 17° BTDC @ idle

HINT: The timing mark moves in a range between 4° and 17°.

5. DISCONNECT TOYOTA HAND-HELD TESTER OR OBDII SCAN TOOL AND TIMING LIGHT
