1. Connect the hand-held tester or OBD II scan tool to the DLC3.
2. Enter DATA LIST MODE on the hand-held tester or OBD II scan tool.
Ignition timing: 8 to 12° BTDC
HINT: Please refer to the hand-held tester or OBD II scan tool operator's manual if you need help to select DATA LIST.
c. When not using hand-held tester or OBD II scan tool:
1. Using SST, connect terminals 13 (TC) and 4 (CG) of DLC3.
