5. Connect the special tool (MB991658) to the harness side
of the engine coolant temperature sensor connector.
6. Connect the special tool [MB991791(APS)] to the special
tool (MB991658).

NOTE
Since the resistance value of the special tool (APS)
indicates a low engine coolant temperature, engine speed
increases.

the end, check that the engine speed decreases and
the radiator fan motor rotates.
9. When the lever of the special tool (APS) is turned to
the reverse direction, check that the voltage between
terminals of the radiator fan motor connector gradually
decreases from the battery voltage to 0 V.
10. If inoperable, replace the radiator fan controller.
(Refer to P.14-15.)
11. Install the center under cover.

2. Insert the special tool at the back of the radiator fan
motor connector.
3. Connect the special tool to the circuit tester.
4. Start the engine and run it at idle.
5. Turn the A/C switch to the ON position and hold the
engine coolant temperature at 80_C or lower.
