Pin Voltage Tests

NOTE: Power seat ECU is only used on models with driving position memory.

Power seat ECU is located under driver seat and contains 2 electrical harness connectors. See Figure. Using DVOM, check voltage between specified power seat ECU terminals under specified condition. See Fig 1 and Fig 2 . If voltage is not within specification, repair wiring harness or replace components as necessary. See MEMORY SYSTEMS in SYSTEM WIRING DIAGRAMS article. If voltages are within specification, power seat ECU may be faulty. If necessary to replace power seat ECU, see POWER SEAT ECU under REMOVAL & INSTALLATION.
