Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT MIRROR POSITION SENSOR CONNECTOR CONDITION • Turn the ignition switch to OFF position. • Disconnect the negative battery cable. • Disconnect mirror position sensor connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to the next step.
No | Go to the next step.
2 | INSPECT MIRROR POSITON SENSOR • Inspect the mirror position sensor. (See POWER OUTER MIRROR INSPECTION.) • Is the mirror position sensor normal? | Yes | Go to the next step.
No | Replace the power outer mirror, then go to the next step. (See POWER OUTER MIRROR REMOVAL/INSTALLATION.)
3 | INSPECT POSITON MEMORY CONTROL MODULE CONNECTOR CONDITION • Disconnect position memory control module connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to the next step.
No | Go to the next step.
4 | INSPECT POSITION MEMORY CONTROL MODULE CIRCUIT FOR OPEN CIRCUIT • Position memory control module and mirror position sensor connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side): ― Mirror position sensor terminal 2A—Position memory control module terminal 2F • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for possible open circuit, then go to the next step.
5 | VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Reconnect the negative battery cable. • Clear the DTC using the M-MDS. (See CLEARING DTC [POSITION MEMORY CONTROL SYSTEM].) • Switch the ignition to ON. • Perform the DTC inspection using the M-MDS. (See DTC INSPECTION [POSITION MEMORY CONTROL SYSTEM].) • Is the same DTC present? | Yes | Replace the front seat slide adjuster. (See FRONT SEAT SLIDE ADJUSTER REMOVAL/INSTALLATION.)
No | DTC troubleshooting completed.
