Note
Use a timing light that detects primary signals.
Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
Note
Confirm the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine.
When checking the ignition timing, the transmission should be in neutral.
Using a timing light, check the ignition timing.
| Standard ignition timing |
|---|
| 8 to 12° BTDC @ idle |
Remove SST from the DLC3.
Check the ignition timing.
| Standard ignition timing |
|---|
| 8 to 18° BTDC @ idle |
Check that the ignition timing advances immediately when the engine speed is increased.
Disconnect the timing light from the engine.
Install the air cleaner case LH with the 2 nuts.
Connect the air cleaner cap LH.
Install the No. 1 air cleaner inlet with the 2 bolts.
Install the engine room side cover LH with the 5 clips.
Install the air cleaner inlet cover with the 5 clips.
Install the V-bank cover.
CHECK IDLE SPEED
Warm up and stop the engine.
Tech Tips
A warmed up engine should have an engine coolant temperature of over 80°C (176°F) and an engine oil temperature of 60°C (140°F), and the engine rpm should be stabilized.
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
Note
Switch off all accessories and the A/C before connecting the intelligent tester.
Race the engine at 2500 rpm for approximately 90 seconds.
Push the intelligent tester main switch on.
Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Engine Speed
| Standard idle speed |
|---|
| 700 to 800 rpm |
Note
When checking the idle speed, the transmission should be in neutral.
Tech Tips
Refer to the intelligent tester operator's manual for further details.
If the idle speed is not as specified, check the air intake system.
Disconnect the intelligent tester from the DLC3.
When not using the intelligent tester:
Using SST, connect a tachometer probe to terminal 9 (TAC) of the DLC3.
Note
Confirm the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine.
Race the engine speed at 2500 rpm for approximately 90 seconds.
Check the idle speed.
| Idle speed (Transmission neutral position) |
|---|
| 700 to 800 rpm |
If the speed is not as specified, check the air intake system.
Disconnect the tachometer from the DLC3.
CHECK CO/HC
Tech Tips
This check determines whether or not the idle CO/HC complies with regulations.
Start the engine.
Keep the engine speed at 2500 rpm for approximately 180 seconds.
Insert the CO/HC meter testing probe at least 40 cm (1.31 ft) into the tailpipe during idling.
Immediately check CO/HC concentration at idle and 2500 rpm.
Tech Tips
When performing the 2 mode (2500 rpm and idle) test, follow the measurement order prescribed by the applicable local regulations.
If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.
Check the air fuel ratio sensor Click here and heated oxygen sensor Click here operation.
See the table below for possible causes, and then inspect and correct the applicable causes if necessary.
| CO | HC | Symptom | Causes |
|---|---|---|---|
| Normal | High | Rough idle |
|
| Low | High | Rough idle (Fluctuating HC reading) |
|
| High | High | Rough idle (Black smoke from exhaust) |
|
CHECK ENGINE OIL LEVEL
Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low level mark and full level mark.
If low, check for leakage and add oil up to the full level mark.
Note
Do not fill engine oil above the full level mark.
Tech Tips
A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.
When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.
If low quality oil or oil of an inappropriate viscosity is used.
When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.
When leaving the idling for a long time, or when driving frequently through heavy traffic.
When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.
