Function Specification E&E Department EC Team 3 SUPPLEMENT
Driver Door Ajar SW
4 Door Ajar SW
Equivalent Logic to
3 Door Ajar SW BCMBCM
After add the Key Illumination function, the 4 Door Ajar SW has to compart into Driver Door Ajar SW and 3 Door Ajar SW, for Driver Door Ajar SW information is needed to judge the state of the Key Illumination light. But in other cases (such as 2.1 Dome lamp relay control, 2.4 Central lock/unlock, 2.9 Alarm), it will not bring any difference to it’s original inputs or outputs, so the two diagram can be replaced each other freely.
