2014 Nissan Frontier Pro4x....I have no low beams....Light bulbs are good fuses are too....Can't find the low beam relay.
System Description INFOID:0000000009478426 Control of the headlamp system operation is dependent upon the position of the combination switch (lighting and turn signal switch). When the combination switch (lighting and turn signal switch) is placed in the 2nd position, the BCM (body control module) receives input requesting the headlamps and park lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate. HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION With the combination switch (lighting and turn signal switch) in the 2ND position and placed in HIGH position, the BCM receives input requesting the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a signal to the BCM. This input is communicated to the IPDM E/R via the CAN communication lines. The CPU of the combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R controls the headlamp high relay coil which supplies power to the high beam headlamps. The combination meter receives a high beam request signal (ON) via the CAN communication lines and turns the high beam indicator lamp ON.
Relays are located in the underhood fuse relay box , look inside the lid for location #

Would you give me an idea of how you are going about deciding on what parts to replace? Are you using any test equipment? Are you using a scan tool or code reader? If so, are there any codes stored? I have two ideas that may apply to your "Start/Stop" issue. What is your vehicles security system doing? Is the Security warning light staying on during startup? Is so, I would focus on that system. If not, you may need to take a closer look at the ECM. Let me know what is going on and if you need more help.
