Code Tech Notes
Remedy:
Switch off engine.
Disconnect injector and coil harness multi plugs and go to step 1 of the test below.
Test:
1. Ensure the harness continuity injector pin 1 is correctly wired to PI 119/005. If this gives a positive result then go to step 2. If the circuit is open then find and correct the wiring fault, re-connect the harness and go to step 13.
2. Ensure the harness continuity in each injector pin 2 is correctly wired to GEMS ECM connection. If this gives a positive result go to step 3. If the circuit is open then find and correct the wiring fault, re-connect the harness and go to step 13.
3. Ensure the harness continuity from each coil pin 1 is correctly wired to GEMS ECM connection. If this gives a positive result then go to step 4. If the circuit is open then find and correct the wiring fault, re-connect the harness and go to step 13.
4. Ensure the harness continuity from each coil pin 1 is correctly wired to RS 001/010. If this gives a positive result then go to step 5. If the circuit is open then find and correct the wiring fault, re-connect the harness and go to step 13.
5. Ensure the harness insulation from each injector pin 1 is correctly wired to ground. If this gives a positive result then go to step 6. If it short circuits then find and correct the wiring fault, re-connect the harness and go to step 13.
6. Ensure the harness insulation from each injector pin 2 is correctly wired to ground. If this gives a positive result then go to step 7. If it short circuits then find and correct the wiring fault, re-connect the harness and go to step 13.
7. Ensure the harness insulation from each coil pin 1 is correctly wired to ground. If this gives a positive result then go to step 8. If it short circuits then find and correct the wiring fault, re-connect the harness and go to step 13.
8. Ensure the harness insulation coil from each pin 2 is correctly wired to ground. If this gives a positive result then go to step 9. If it short circuits then find and correct the wiring fault, re-connect the harness and go to step 13.
9. Check the voltage reading between each injector pin 2 connector and PI 119/005. If it reads 0V then go to step 10. If it reads Vbatt then find and correct the wiring fault, re-connect the harness and go to step 13.
10. Check the voltage reading of each injector pin 1 connector and PI 119/005. If it reads 0V then re-connect the harness and go to step 11. If the reading is Vbatt then find and correct the wiring fault, re-connect the harness, re-connect the injector, coil and harness and go to step 13.
11. Ensure the fuel pump pressure lies between 3 - 4 bar (absolute) and also that it changes with engine load. If this gives a positive result then go to step 12. If the pressure is out of range then correct and go to step 13.
12. Check to find out if the fault code for crankshaft position sensor has been recorded. If it has not then go to step 13. If it is faulty then correct and go to step 13.
13. Clear the fault. Then in order to check if the fault code has been cleared perform the service drive cycle. If this gives a positive result then stop. If the fault is still present then go to step 14.
14. Repeat the diagnostic procedure. If this now omits a positive result then stop.
