| 9003825 | 2022-09-15. Service bulletin. LATCH, Hood For the following concerns, please verify secondary plunger switch before replacing hood latch with primary switch. Please refer to service information for complete diagnostics of the secondary plunger switch which is located in the left front under hood on RU, MP, and WK/WD and left rear under hood on KL. 1) Electronic Stop Start Message on Cluster or DTC P152F without hood ajar illuminated. 2) KL Hood ajar light is on or unlatched hood due to high closing effort. (KL hood may have a higher closing effort to latch the hood as rubber bumper interference is set purposely high to prevent hood flutter at highway speeds) If stop start message or DTC P152F is present on vehicles without a hood ajar light illuminated, the issue is not related to the primary hood latch switch. |
| 9004401 | 2022-08-22. Service bulletin. DIFFERENTIAL, Rear Axle (KL 4WD w/DK2 = 1-SPEED RDM) The Differential, Rear Axle (aka RDM) design, pump design, Driveline Control Module (aka DLCM) hardware & software and pressure sensor have all changed in the past few years. The changes are not interchangeable and each had a separate implementation date. Please comprehend it to avoid repeat repairs. There are 2 sections each with 3 sub-sections: 1) For 2014/5 VINs with DK2 = 1-spd RDM 2) For 2016 and later VINs with DK2 = 1-spd RDM 1) For 2014/5 VINs with DK2 = 1-spd RDM 2014 - 2015 VINs were built with a 1-speed RDM used a 24 plate clutch design. New service RDMs 68550586A$ use a 20-plate design. 1.1) If replacing the RDM · 24 plate and 20-plate design RDMs are NOT interchangeable unless the Drive Line Control Module (DLCM) is also replaced. · 68550586A$ service RDMs have a 20 clutch plate design · Not all 20-plate RDMs have the new pump design. The new pump requires a new DLCM. · All new service RDMs are shipped with the new pump design. · If a new 68550586AA service RDMs is installed, then replace the DLCM with new DLCM 68540647AA - 1-spd designed for the 20-plate RDM. 1.2) If replacing the DLCM but not the RDM or pump assembly, then · If the RDM is the original 24 plate design then use 68540645AA - 1-spd, 24 plate DLCM AND replace the pump with 68551790AA · If the RDM is the new 20 plate design then use 68540647AA - 1-spd, 20 plate DLCM AND also replace the pump with 68551790AA new pump unless the RDM previously had a 68551790AA installed. 1.3) If replacing the pump assembly, then use 68551790AA (new pump) AND also replace the DLCM with the version that matches the correct version of the RDM (24 or 20 plate). · Use 68540645AA for the 24 plate RDM with a new pump. · Use 68540647AA for the 20 plate RDM with a new pump. 2) For 2016 and later VINs with DK2 = 1-spd RDM Early 2016 were built with 68090612AG 24 plate RDMs. Use Section 1 ?For 2014/5 VINs with DK2 = 1-spd RDM? to resolve.
