1. MIL is ON.
2. Engine does not start.
3. Engine stops after few seconds.
4. Engine vibration and noise noticed.
5. Reduced torque mode [Restricted
performance.
6. Disables the Pilot injection;
7. Disables RVD.
8. Disables EGR.
9. IMV operates without trims.
10. Cylinder balancing is deactivated.
11. High pressure Leak detection test is
prevented.
12. IMV is fully open;
13. System Pressure is limited to 800 bar.
14. Rail pressure build measurement is
deactivated.
15. Disables the Rail pressure control fault
detection.
16. Rail pressure set to 800 bar.
This DTC gets logged if the
IMV drive electrical
connection is short circuited
with Ground.
1. Check IMV connection.
Remove and check for
oxidation and damages.
2. Check IMV.
3. Check Electrical continuity.
4. Check ECU.
1. Check and ensure IMV connector is connected to
IMV.
2. Check IMV connector for oxidation and rust and
damages; clean the connector for rust; dirt etc.
reconnect properly.
3. Check continuity between ECU pin 11 and IMV
connector as per circuit schematic; replace the
connector/harness if found faulty.
4. Check IMV ;( Provide IMV internal resistance at
room temperature for checking). Replace IMV if
found faulty.
5. Check ECU; if problem still persist; replace the
ECU.
6. After rectification ensure the following before
handing over the vehicle to customer.
a) Please fit the IMV with it's connector and
remove the ECU connector and ensure
continuity between IMV and ECU connector.
b) Perform actuator test for IMV.
