Inspection

1. HDS DLC - Connect

2. DTC - Check

3. Engine - Warm Up

4. Idle Speed - Check

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 No. 1 ignition coil harness.

3. Aim the light toward the pointer (A) on the timing belt lower cover. Check the ignition timing under a no load condition (headlights, blower fan, rear window defogger, and air conditioner are turned off).

4. If the ignition timing differs from the specification, check the camshaft timing. If the camshaft timing is OK, check for any authorized service information related to the DTCs or symptoms you are troubleshooting, 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.
