Load compensation inspection

Start the engine and let it idle.
Connect the M-MDS to the DLC-2.
Verify that DTC P0506:00 or P0507:00 is not displayed. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN L (WITHOUT CYLINDER DEACTIVATION))] .)
- If DTC P0506:00 or P0507:00 is displayed, perform the DTC inspection. (See DTC P0506:00, P151B:00 [PCM (VIN L (WITHOUT CYLINDER DEACTIVATION))] .) (See DTC P0507:00 [PCM (VIN L (WITHOUT CYLINDER DEACTIVATION))] .)
Select the RPM PID.
NOTE:
- Excludes temporary idle speed drop just after the loads are turned on.
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 A/C DOES NOT WORK SUFFICIENTLY [FULL-AUTO AIR CONDITIONER] .) (See A/C DOES NOT WORK SUFFICIENTLY [MANUAL AIR CONDITIONER] .) (See A/C IS ALWAYS ON OR A/C COMPRESSOR RUNS CONTINUOUSLY [FULL-AUTO AIR CONDITIONER] .) (See A/C IS ALWAYS ON OR A/C COMPRESSOR RUNS CONTINUOUSLY [MANUAL AIR CONDITIONER] .)
  - Electrical load
  - Charging system (See BATTERY INSPECTION .) (See GENERATOR INSPECTION [VIN L (WITHOUT CYLINDER DEACTIVATION)] .)
