Load compensation inspection
- Start the engine and let it idle.
- Connect the M-MDS to the DLC-2.
- 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 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 .) (See GENERATOR INSPECTION .)
Idle-up speed (MT: Neutral position, AT: P, N position)
- No load: 660-760 rpm (MT), 670-770 rpm (AT)
- A/C on (With A/C): 720-870 rpm (MT), 700-800 rpm (AT)
