5. Measure the resistance between joint connector (3) terminal 19 and multi-center display unit (middle-grade type) connector terminal 12.
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 multi-center display (middle-grade type) may be suspected. Diagnose the
multi-center display (middle-grade type). Refer to "Inspection Procedure 1: Communication with Scan Tool is Not Possible. (Middle Grade
Type)".
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 multi-center display unit (middle-grade type) connector.
