5. Measure the resistance between joint connector (3) terminal 5 and ETACS-ECU connector terminal 72.
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 ETACS-ECU may be suspected. Diagnose the ETACS-ECU by referring
to GROUP 54B, Diagnosis P.54B-79.
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 ETACS-ECU connector.
STEP 11. Check A/C-ECU connector C-10 <manual air conditioning system (low)> or C-15 <manual air conditioning system (middle) or
automatic air conditioning system> for loose, corroded or damaged terminals, or terminals pushed back in the connector.
