Load compensation inspection

1. Start the engine and let it idle.
2. Connect the M-MDS to the DLC-2.
3. Verify that DTC P0506:00 or P0507:00 is not displayed. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
   • If DTC P0506:00 or P0507:00 is displayed, perform the DTC inspection. (See DTC P0506:00, P151B:00 [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) (See DTC P0507:00 [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
4. Select the RPM PID.
   NOTE:

   • Excludes temporary idle speed drop just after the loads are turned on.
5. Verify that the engine speed is within specification under each load condition.
   • If the load condition is not as specified, inspect the following:
     • A/C switch and related wiring harness system (A/C request signal is always on or off) (See NO. 23 A/C DOES NOT WORK SUFFICIENTLY .) (See NO. 24 A/C IS ALWAYS ON OR A/C COMPRESSOR RUNS CONTINUOUSLY .)
     • Electrical load
     • Charging system (See BATTERY INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) (See GENERATOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT I-ELOOP)] .)
