Remote Control Mirror Ecu Circuit: Lx470
Disconnect remote control mirror ECU harness connectors. Using an ohmmeter, check for continuity between specified remote control mirror ECU connector terminals (harness side) within specified conditions. See REMOTE CONTROL MIRROR ECU CIRCUIT CONTINUITY (LX470) table. See Fig 1. If continuity does not exist, repair wiring harness as necessary. If continuity exists, check remote control mirror ECU. See REMOTE CONTROL MIRROR ECU PIN VOLTAGES under COMPONENT TESTS.
