## NHTSA's summary

Tech Tips \(Clicking Noise from Rear End\): This document informs For a complaint of ?clicking noise when backing up and then braking?, be sure to check the lower outboard control arm in the rear suspension for any play in the bushing. The noise could be mistaken for a differential noise if using chassis ears, because of the noise transferring through the rear axle.

If you have a complaint of DTCs for the low side fuel pressure being out of specification \(e.g. P310B\), check the fuel pressure with BOTH a mechanical gauge and by the display in Measured Value Block 103. The readings should be 1 bar higher in the MVB due to reading atmospheric pressure \+ fuel pressure. If the mechanical gauge reading is within specification BUT the MVB 103 reading is not 1 bar higher, check for a possible faulty G410 Low Fuel Pressure sensor.
