Without Scan Tool

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) in 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).

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. Diagnostic Trouble Code Descriptions
