5. Measure the resistance between joint connector (3) terminal 6 and A/C-ECU connector terminal 5 <manual air conditioning system (low)> or 15
<manual air conditioning system (middle) or automatic air conditioning system>.
OK: 2 ohms or less
CAUTION: Strictly observe the specified wiring harness repair procedure. For details Service Precautions/Vehicle Damage Warnings.
Q: Do all the resistances measure 2 ohms or less?
YES: If all the resistances measure 2 ohms or less, power supply to the A/C-ECU may be suspected. Diagnose the air conditioning system. Refer
to Manual A/C diagnosis, "Inspection Procedure 10: Malfunction of the A/C-ECU Power Supply System".
NO: If either of the resistances measures more than 2 ohms or all the resistances measure more than 2 ohms, repair the wiring harness between
joint connector (3) and the A/C-ECU connector.
