Fix the injector (a common problem on DV6C engines) and the ABS light should clear. Note that injectors are numbered from the flywheel end.
Hi Richard would you happen to have the wiring diagram for injectors to Engine ECU at all as mine is playing up as I am trying to check continuity between pin 2 of each injector and engine ECU (48 pin ) or if anyone else has one many thanks
