Driver's Seat Switch Isolation

  1. Turn ignition off. Ground memory seat module diagnostic connector (located under driver's seat) to enter Mode 1 diagnostics. Operate power seat switch until a beep is heard. This ensures that memory seat module and Mode 1 diagnostics are activated. During Mode 1 diagnostics, all seat and recliner motions are disabled.
  2. If beep was heard in step 1), go to next step. If beep was not heard in step 1), ensure battery voltage exists at memory seat module connector C1 terminal No. 3 (Orange wire) and connector C2 terminal "A" (Red wire). Repair as necessary. If battery voltage exists as indicated, repair poor ground connection at memory seat module diagnostic connector.
  3. Operate driver's power seat switch and recliner switch in all positions that do not work. If memory seat module beeps once for each switch position, go to step 5). If memory seat module does not beep once for each switch position, go to next step.
  4. With inoperative switch position pressed, use ohmmeter to check resistance between appropriate memory seat module terminal and chassis ground. See WIRING DIAGRAMS . If resistance is less than one ohm, replace memory seat module. If resistance is greater than one ohm, replace driver's seat switch.
  5. Disconnect inoperative motor. Apply battery voltage to one motor terminal, and ground other motor terminal. If motor operates, check for poor connection, open, or short to ground in circuits to motor. If circuits are okay, replace memory seat module. If motor does not operate, check cables and linkage for binding. If cables and linkage are okay, replace motor.
