Idle Speed Inspection
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation.)
2. Verify that the idle speed (M-MDS: RPM) is within the specification. (See PCM INSPECTION [MZR 2.0 DISI i-stop].)
Ignition Timing Inspection
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation.)
2. Verify the ignition timing (M-MDS: SPARKADV) using the PID/DATA monitor function of the M-MDS. (See PCM INSPECTION [MZR 2.0 DISI i-stop].)
3. Verify that ignition timing advances when the engine speed increases gradually.
Idle Mixture Inspection
1. Verify that the idle speed and ignition timing are within the specification. (SeeIgnition Timing Inspection.) (SeeIdle Speed Inspection.)
2. Insert an exhaust gas analyzer to the tailpipe.
3. Verify that the CO and HC concentrations are within the regulation.
Idle-up Speed Control Inspection
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation.)
2. Verify that the engine speed (M-MDS: RPM) is within the specification when each load is applied. (The speed decrease just after the load is applied is not considered.) (See PCM INSPECTION [MZR 2.0 DISI i-stop].)
