2. 4WD ECM : Connect, EMC : Disconnect.
3. Measure resistance between EMC (+) terminal of EMC harness connector and EMC (-) terminal of EMC harness connector. (Component side)
A. Specification : Approx 2.4 Ohms





CAUTION: The above value is only for reference. The actual value may differ from it according to various engine condition.

4. Is "resistance" display near the specified value ?
YES
1) Substitute with a known-good "4WD-ECM" and check for proper operation. If the problem is corrected, replace "4WD-ECM" and then go to "Verification of Vehicle Repair" procedure.
NO
