    Here it is from the manual:

    1. WARM UP ENGINE Allow the engine to warm up to normal operating temperature.
    2. CONNECT TOYOTA HAND-HELD TESTER OR OBD II SCAN TOOL

    1. Connect the TOYOTA hand-held tester or OBD II scan tool to the DLC 3.
    2. Please refer to the TOYOTA hand-held tester or OBD II scan tool operators manual for further details.

    3. CHECK IGNITION TIMING
    1. Using Special Service Tool (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.
    2. Using a timing light, connect the test probe to the No.1 high-tension cord.
    3. Check ignition timing.
    Ignition timing: 3 - 7°BTDC @ idle
    4. 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 OBD II SCAN TOOL AND TIMING LIGHT
