to enter the self-diagnosis mode.
|
|
(5) |
When entering the self-diagnostic mode, the switch indicator
blinks once.
|
|
• |
Up to 2 fault codes can be output, and when 2 fault
codes are detected, each fault code is sequentially
repeated with a cycle of 2 seconds.
|
|
• |
The fault details can be checked through the self-diagnosis
mode in the same way for both the 1st and 2nd row seats.
|
|
• |
The shape of the heater & air ventilated seat switch
