Subject: | Current Draw from Rear Seat Entertainment (RSE) After DTCs Cleared or SPS Programming with Tech 2® |
Models: | 2007-2008 Chevrolet Caprice, Lumina (Export Only) |
This bulletin is being updated from Issue 2 by including an additional cause for RSE current draw. Please replace your copy of the previous bulletin H07-08-06.
When vehicles equipped with the Rear Seat Entertainment (RSE) option undergo either of the following there is potential that the RSE module will not correctly reset. This may result in a constant current draw when not in use and may lead to a serious dead battery situation.
• | flash programming (SPS) of any module on either of the GM LAN networks |
OR |
• | clearing of Rear Seat Entertainment (RSE) Diagnostic Trouble Codes (DTCs), including clearing DTC’s from the whole vehicle (regardless of whether there were DTCs logged in the RSE or not). |
The RSE system may not respond to a command to return to a "normal" state after SPS programming or DTC clearing and can potentially stay in "programming" mode.
Revised software was introduced into production to address the SPS-related issue only from the following breakpoint. .
Important: A production fix for the issue related to DTC clearing is currently being developed
