Initial Inspection and Diagnostic Overview

Using the HDS (preferred method)

NOTE: Make sure you have the latest software on the HDS.

1. Go to B-CAN System Diagnostic Test Mode A to check for "Connected Units" and DTCs.
2. If no DTCs are retrieved, go to B-CAN System Diagnosis Test Mode C or Test Mode D. Troubleshooting - B-CAN System Diagnosis Test Mode C

Without the HDS (use only if HDS is not available)

The self-diagnostic function of the driving position memory system detects system problems. If a system problem is detected, the buzzer built into the power seat control unit sounds for 5 seconds and the system stores a DTC. The status and DTC information can be retrieved through the driving position memory switch indicators.

Displaying the Diagnostic Trouble Code (DTC)

1. Turn the ignition switch OFF, and move the seat to a non-memorized position.




2. Press and hold the MEMO button (A) and both position buttons (B) on the driving position memory switch at the same time.
3. Turn the ignition switch ON (II), and wait at least 1 second, then release the three buttons.
4. After 1 second, the position button indicators (C) will blink to show the DTC.

Status and DTC Indications




No System Problem Detected
If there is no DTC stored, the indicators blink only once (3 seconds).




System Problem Detected

If a system problem occurs, and a DTC is stored, the indicators will show the DTC. The first digit is indicated by the number of long {1 second) blinks, and the second digit is indicated by the number of short (0.26 second) blinks. There is a 3 second break between each DTC when there are multiple DTCs.

Canceling the DTC Indication
- Turn the ignition switch OFF or
- Press the MEMO button, or position button 1, or position button 2, or
- Press one of the seat adjustment switches.

Erasing the DTC from Memory

With the HDS
Use the HDS to clear DTCs in the power seat mode of the body electrical select menu.

Without the HDS
Make sure you have the anti-theft code for radio and navigation system, then write down the audio presets. Turn the ignition switch OFF. Remove fuses No. 7 (10 A), No. 14(20 A) and No. 16(20 A) from the under-dash fuse/relay box. Wait at least one minute and then plug them back in.
