Ignition Timing: Testing and Inspection

IGNITION TIMING

INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.





2. INSPECT IGNITION TIMING
a. When using a hand-held tester or OBD II scan tool.
(1) Connect a hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Date Link Connector 3 (DLC3)
(2) Please refer to the hand-held tester operator's manual for further details.
Ignition timing: 7 to 24° BTDC at idle (Transmission in neutral)
(3) Disconnect the hand-held tester or OBD II scan tool from the DLC3.





b. When not using a hand-held tester or OBD II scan tool.
(1) Remove the air cleaner cap.
(2) Connect the tester probe of a timing light to the wire of the ignition coil connector for the No.1 cylinder.





(3) Using SST, connect terminals TC and CG of the DLC3.
SST 09843-18040





(4) Using the timing light, check the ignition timing.
Ignition timing: 8 to 12° BTDC at idle (Transmission in neutral position)
(5) Remove the SST from the DLC3.
(6) Check the ignition timing.
Ignition timing: 7 to 24° BTDC at idle (Transmission in neutral position)
(7) Disconnect the timing light from the engine.
(8) Install the air cleaner cap.
