Test L: the Delayed Accessory Is Inoperative/Does Not Operate Correctly

PINPOINT TEST L: THE DELAYED ACCESSORY IS INOPERATIVE/DOES NOT OPERATE CORRECTLY


L1-L3:






Normal Operation
The delayed accessory relay, which is integral to the smart junction box (SJB), receives power from the battery junction box (BJB) through circuit SDC02 (RD). When the ignition key is turned ON, the SJB activates the delayed accessory relay. The delayed accessory relay provides power to the LH front window control switch through circuit CBP47 (GN/BU). On MKX, the delayed accessory relay also provides power to the RH front window switch and the LH and RH front window motors through circuit CBP41 (BU). The delayed accessory relay remains active for 10 minutes after the ignition key is turned OFF or until either front door is opened.

Possible Causes
- SJB
- Door ajar switches
