Ignition Timing Inspection

NOTE: If a DTC is present, diagnose and repair the cause before continuing with this inspection.

3. Engine - Warm Up
1.
Start the engine. Hold the engine speed at 3,000 min-1 (rpm) with no load (in P or N) until the radiator fan comes on, then let it idle.

5. SCS - Short
1.
Turn the vehicle to the OFF (LOCK) mode.
2.
Jump the SCS line with the HDS, and wait more than 1 minute.

6. Ignition Timing - Inspect
1.
Start the engine.
2.
Connect the timing light to the service loop (white tape).
3.
Aim the light toward the pointer (A) on the cam chain case. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off).
Ignition Timing
8 ±2 ° BTDC (RED mark (B)) at idle in P or N
4.
If the ignition timing differs from the specification, check the camshaft timing. If the camshaft timing is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the system works properly, and the PCM was substituted, replace the original PCM.
5.
Disconnect the HDS and the timing light.
