Load compensation inspection

Start the engine and idle it.
Connect the M-MDS to the DLC-2.
Verify that P0506 or P0507 is not displayed.
- If P0506 or P0507 are displayed, perform DTC inspection.
  (See DTC TABLE [L3] .)
Access the RPM PID.
NOTE:
- Excludes temporary idle speed drop just after the loads are turned on.
Verify that the engine speed is within the specification under each load condition.
- If load condition is not as specified, inspect the following:
  - A/C switch and related wiring harness
    (See CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER] .)
    
    (See CLIMATE CONTROL UNIT INSPECTION [MANUAL AIR CONDITIONER] .)
  - Fan switch and related wiring harness
    (See CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER] .)
    
    (See CLIMATE CONTROL UNIT INSPECTION [MANUAL AIR CONDITIONER] .)
