2 - Checking the balance of the injector return flows:
3 - Removing the tool:
Disconnect the pipe from an injector:
–press on the injector clip,
–pull vertically on the end piece of the pipe of tool Mot.1760, placing a wipe on the end piece to prevent run-off.
Lift the end piece vertically so that the fuel contained in the pipes flows into the measuring cylinders of tool Mot.1760.
Remove the other 3 pipes using the same procedure.
TEST8
CONTINUED 5
Does the engine start? – Fit Mot. 1760 as shown in the tool fitting procedure.
–Start the vehicle or perform a 15 second starting sequence
(with ignition key).
–Measure the length travelled by the diesel fuel in the pipes of the
Mot. 1760.
–Replace the injector if the length travelled by the fuel is more than
10 cm compared with the average of the other three injectors. NO
YES
–The injector return pipes must be fitted to the injectors.
–Start the engine.
–Display the Fuel circuit sub-function in the CLIP diagnostic tool.
–Raise the temperature of the engine.
–Read the diesel fuel temperature with PR063 Fuel temperature until a diesel fuel temperature greater than
50˚C is reached
–Switch off the engine.
–Fit Mot. 1760 as shown in the installation procedure (see step 1).
–Check the value of the PR038 Rail pressure.
–Ask another Cotech to monitor the rise in fuel in the cans during engine turnover, as one of the cans will fill up
quickly if one of the injectors is leaking.
–Start the engine.
–Accelerate the engine until the pressure in the rail is 550 bar:
●if the engine speed is less than 3,000 rpm, maintain this pressure.
●if the engine speed is greater than 3000 rpm, reduce the engine speed until the rail pressure is 500 bar and
maintain this pressure.
–Maintain these conditions for one minute.
–Release the accelerator pedal and maintain the idle speed for 10 seconds.
–Switch off the engine.
–Measure the quantity of fuel contained in each measuring cylinder.
–Replace the injector if the quantity of fuel is more than 50 ml.
–Remove Mot. 1760 as shown in the tool removal procedure (see step 3).
IMPORTANT:
Use a cleaning cloth (part number 77 11 211 707) to absorb fuel run-off.
