Radio Frequency Hub Module Initialization - Export With Column Lock Module
On vehicles equipped with the optional export premium Vehicle Theft Alarm, when either the Radio Frequency Hub Module (RFHM) or the shaft lock module (also known as the Electronic Steering Column Lock/ESCL) is replaced with a new unit, the existing RFHM or ESCL MUST also be replaced with a new unit. In other words, any time either the RFHM or the ESCL is replaced with a new unit, BOTH the RFHM and the ESCL MUST be replaced with new units, WITHOUT EXCEPTION. Following replacement of BOTH the RFHM and the ESCL, the two modules MUST be initialized using diagnostic scan tool routines in the EXACT SEQUENCE found in the initialization procedure. Refer to STANDARD PROCEDURE . Failure to follow this sequence may result in BOTH the new RFHM and the new ESCL being rendered unusable, requiring BOTH units to be replaced a second time.
