- Clear the DTCs with the HDS.
- Turn the ignition switch to LOCK (0), and then back to ON (II).
- Check for DTCs with the HDS. Is DTC B1802 indicated? YES - Replace the power seat control unit. NO - Intermittent failure. The driving position memory system is OK at this time. Check for loose or poor connections at the power seat control unit connector.
