[2] Check injector bank 2.: Short circuit to ground

Test 1: Check injector bank 2.

1. Check injector bank 2.
Special tools

- Test cable 266 589 01 63 00
- Socket box 129 589 00 21 00
Test sequence

- Switch off ignition.
- Disconnect the socket M at control module N3/9 (CDI control unit).
- Connect 126-pole socket box at engine wiring harness.
- Measure resistance with multimeter between socket (M.25) 25 of the 126-pole socket box tester and ground
- Measure resistance with multimeter between socket (M.26) 26 of the 126-pole socket box tester and ground
- Measure resistance with multimeter between socket (M.27) 27 of the 126-pole socket box tester and ground
Specified value

- Resistor infinite ohms
Question

- Are the measurement values OK?


YES
The measurement values are OK.Possible cause and remedy in the case of stored fault code

- Check lines between control unit N3/9 (CDI control unit) and component Y76y4 (Fuel injector cylinder 4) as well as connections and connectors for damage, correct fitting, loose contact and corrosion, and repair or replace as necessary.
- Check lines between control unit N3/9 (CDI control unit) and component Y76y5 (Fuel injector cylinder 5) as well as connections and connectors for damage, correct fitting, loose contact and corrosion, and repair or replace as necessary.
- Check lines between control unit N3/9 (CDI control unit) and component Y76y6 (Fuel injector cylinder 6) as well as connections and connectors for damage, correct fitting, loose contact and corrosion, and repair or replace as necessary.
End of test

NO
The measurement values are not OK.Further procedure

- Test cables and connections, rectify any short circuit.
