Front suspension dropped and wont come up with a trouble code c277

B1941 41 RH primary crash sensor feed/return circuit open GO to DTC B1941.
DTC B1941: RH PRIMARY CRASH SENSOR FEED/RETURN CIRCUIT OPEN- LAMP FAULT CODE 41

Normal Operation
The voltage at Pin C276-16, Circuit 617 (PK/O) is set by the air bag diagnostic monitor to be slightly less than battery voltage. Circuit 617 (PK/O) is connected to Circuit 624 (Y/W) inside RH primary crash sensor. Therefore, the voltage at Circuit 624 (Y/W) and air bag diagnostic monitor Pin C277-24 should be the same as the voltage at air bag diagnostic monitor Pin C276-16, Circuit 617 (PK/O).
The air bag diagnostic monitor periodically pulls the voltage at Pin C276-16, Circuit 617 (PK/O) low to verify the connection to Pin C277-24, Circuit 624 (Y/W). If the voltage at Pin C277-24, Circuit 624 (Y/W) does not pull low as a result of this test, the air bag diagnostic monitor will store in memory DTC B1941 and flash lamp fault code 41 on the AIR BAG indicator. If the connection between Pins C276-16, Circuit 617 (PK/O) and C277-24, Circuit 624 (Y/W) is later serviced, DTC B1941 will be stored in memory.
Possible Causes
Failure to get low voltage at Pin C277-24, Circuit 624 (Y/W) during the test can be caused by:

• an open circuit in the wiring harness in either Circuit 617 (PK/O) or Circuit 624 (Y/W).
• an open circuit inside RH primary crash sensor across Circuit 617 (PK/O) or Circuit 624 (Y/W).
• a short to battery or ignition voltage in any of the Circuits 617 (PK/O), 619 (PK/W), 624 (Y/W), 625 (Y/LG).

has this car got air suspension ? if so check the ride height senors the clip on the lower suspension arm securing the sensor link rod sometimes comes adrift or the sensor may be faulty

unusual for only one corner to be out, the common problems are, air leaks, between valve block and suspension unit, ride level sensors, normally the clamp on the suspension corrodes and allows the sensor to float,it sounds like a air leak on that corner to me. you can buy a leak detection spray to help find the leak. the pump is also troublesome. located front bumper liner lh, but that would affect the whole system, I would check the plastic pipe is ok from the valve block to the suspension unit first, then get the fault codes out of the air suspension module, the valve block is in the boot spare wheel well. hope this helps.

this is common problem normally a faulty air pump behind lh/of front bumper

the only thing will cause the fault light to come on is the pressure in the retention tank located in the trunk underneath the spare tire...,once the pressure drops,then the suspension pump relay makes the pump refil the tank...the cause of this is usually a leaking shock...normally they will leak around the upper caping...one sign is that the car will be lower overnite then normal or if it sits for a long period.if the front is lower then its a front shock..the bumpy ride is the fault system lowering the car from the leak while your riding..

You will need to have suspension computer scanned for codes , these codes will point you in the direction of the problem, a scan tool will be needed to do this,if you can get me the codes i could help you i little more and point you in the right direction.

Sounds like the front "air ride suspension" is out.
That works off rubber bags built into the springs. If one or both has developed a leak/hile, it lets the front end (or rear or both) drop to ride on the bottom of the suspension.
Get the wallet out. It's expensive.
Sorry :-(

dose anyone know where the sensor on 03 bmw x5 front suspension are located.

faulty units replace
