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.
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: 5 to 15° BTDC at idle (Transmission in neutral)
3. Disconnect the hand-held tester and CAN VIM from the DLC3.
b. When not using a hand-held 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 DLC3.

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 DLC3.
