15 Reconnect the battery negative cable and Injector wiring connector
16 Perform Injector coding registration on ECM using scan tool in case any injector is replaced with new one

TASK 3: Removal and Refitting of common rail and fuel pressure sensor
1 Relieve the fuel pressure
2 Disconnect the battery negative cable
3 Remove the engine cover and high pressure pipe of fuel injector and common rail pipe

4 Remove common rail return line to fuel tank
5 Disconnect the Fuel pressure sensor and Fuel pressure regulator wiring connector
6 Remove fuel pressure sensor from common rail
Checking of Fuel pressure regulator

7 Check the resistance between terminals of fuel pressure regulator, compare the resistance value with
manufacturers service manual. If the values are out of specification, replace the common rail with pressure
regulator
8 Clean the common rail

9 Mount the common rail pipe and tighten the common rail mounting bolts
10 Reconnect all the high pressure pipes and tighten with specified torque
