The abs/asc lights are both on I had the car diagnosed but the computer couldnt access the abs system although it got all other info from the car so with no luck there I changed all four wheel sensors checked all fuses which were fine then checked the multiplug at the abs module with a voltmeter the only reading I could get was 7 volts at 1 pin nothing at the rest so I replaced the abs relay but still nothing the the battery is just new and the alternator is putting out 14.6 volts everything is working fine on the dash speedo etc

It is likely there is an internal fault in the ASC/DSC module itself and a new one will need to be coded to the car.

Is that the module located in the engine bay or is there another module located somewhere
