harness side. Is a resistance of less than 2 Ohms registered? CHECK and RENEW the RJB if necessary. CHECK the operation of the No LOCATE and RECTIFY the break in circuit SBR11A (BU/RD) between the L6: CHECK THE GROUND CONNECTION OF THE TRAILER COUPLING MODULE Ignition switch in position 0. 1 Measure the resistance between the trailer coupling module, connector 2 Is a resistance of less than 2 Ohms registered? GO to L7 . No LOCATE and RECTIFY the break in the circuit between the trailer coupling L7: CHECK FOR OPEN CIRCUIT BETWEEN THE TRAILER COUPLING MODULE AND THE CAUTION: The following measurement must only be performed using the Ford approved diagnostic tool digital multimeter. Failure to observe this instruction can lead to Measure the resistance between the trailer coupling module, connector DLC, connector C3DB04, pin 11, circuit VDB07D (VT/OG), wiring harness 1 Is a resistance of less than 2 Ohms registered? GO to L8 . No LOCATE and RECTIFY the break in the circuit between the trailer coupling L8: CHECK FOR OPEN CIRCUIT BETWEEN THE TRAILER COUPLING MODULE AND THE CAUTION: The following measurement must only be performed using the Ford approved diagnostic tool digital multimeter.
