Ignition Timing: Testing and Inspection

CHECK IGNITION TIMING
a) Warm up engine.
1) Allow the engine to warm up to normal operating temperature.





b) Inspect ignition timing (When using a intelligent tester).
1) Connect a intelligent 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 intelligent tester operator's manual for further details.
Ignition timing: 5 to 15° BTDC at idle (Transmission in neutral)
3) Disconnect the intelligent tester and CAN VIM from the DLC3.





c) Inspect ignition timing (When not using a intelligent tester).
1) Connect the tester probe of a timing light to the wire (black - red) of the ignition coil connector for the No. 1 cylinder.





2) Using SST, connect terminals TC and CG of the DLC 3.

3) Using a timing light, check the ignition timing.
Ignition timing: 5 to 15° BTDC at idle (Transmission in neutral)
4) Remove the SST from the DLC 3.
