Manufacturer summary

Original wording in English

IF YOU CONFIRM The client states that either the rear hatch is inoperative, or the rear hatch closes after opening only a small amount, AND DTC B2426-23 for “SPINDLE SENSOR LH” and/or DTC B2427-23 for “SPINDLE SENSOR RH” is stored, AND/OR There is a growling type noise from the rear hatch area when opening/closing the rear hatch. · DTC B2426-23 for “SPINDLE SENSOR LH” and/or DTC B2427-23 for “SPINDLE SENSOR RH” may also be stored. HINT: If any DTC other than B2426-23 and/or B2427-23 is stored, this bulletin does not apply. ACTION Replace ONLY the spindle unit that is confirmed to be setting one of the DTCs listed above and/or causing the growling noise. Do NOT replace both spindle units when diagnosis leads to replacement of only one. HINT: Rear hatch spindle units are not hydraulic systems. If a rear hatch spindle unit appears to be leaking, this is normal drainage of water (rain, car wash, condensation) and design intended water management. Do not replace spindle units for suspected leaking. IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it contains information that is essential to successfully completing this repair.
