Diagnostic Result Display

●

The malfunctioning items are indicated by how many times LEDs on the seat memory switches 1 and 2
flash simultaneously.

●

If the vehicle speed is less than 7 km/h (4 MPH) for 15 seconds after the diagnosis for the seat and steer-
ing wheel systems were completed, the vehicle speed signal is judged malfunctioning.

●

If LH door mirror is malfunctioning, only indicator lamp on the memory switch 1 flashes, and if RH door
mirror is malfunctioning, only indicator lamp on the memory switch 2 flashes.

●

When all the diagnosis are finished normally, the indicator lamps on the memory switches 1 and 2 go off
after the vehicle speed signal diagnosis.

●

If there are multiple malfunctioning parts, the lamps indicate them in sequence from the smallest diagno-
sis trouble code.

●

The diagnosis results repeat until the diagnosis mode is cancelled.
