Ignition Timing: Testing and Inspection
PREPARATION1. Warm up the engine to normal operating temperature.
2. Turn all electric loads OFF.
- Headlight switch
- Blower switch
- Rear window defroster switch
- A/C
3. Connect the SST to the data link connector.
4. Connect a timing light to the engine.
5. Connect a tachometer to the data link connector terminal IG- as shown.
Ignition Timing
1. Perform Preparation. (Refer to above.)
2. Verify that the idle speed is within the specification; if not within specification, adjust the idle speed. (See "Idle Speed" in "Fuel Delivery and Air Induction".)
Idle speed (Neutral): 600-700 (650 ± 50) rpm
3. Set switch A to position 1.
4. Set test switch to SELF TEST.
5. If the SST is not used, connect a jumper wire between the TEN terminal and the GND terminal of the data link connector.
6. Verify that the idle speed is within the specification.
Idle speed (Ground the terminal TEN): 550-750 rpm
7. Verify that the timing mark (yellow) on the crankshaft pulley and the mark on the timing belt cover are aligned.
Ignition timing: BTDC 9° - 11° (10° ± 1°)
10. DISCONNECT the SST.
11. Verify that the ignition timing is within the specification.
Ignition timing: BTDC 6 - 18°
