Since I posted last night, I've been doing some research on the CTS-V oil temp warnings going off, and apparently my year (2004) had an issue.... see the TSB below issued by GM:
ASI Resolution - Engine Oil Tempature Gage Warning (Call TCSC and Reprogram IPC Module) #04-08-49-017A - (Aug 3,2004)
Document ID # 1542045
Engine Oil Tempature Gage Warning (Call TCSC and Reprogram IPC Module)
2004 Cadillac CTS-V
Built prior to breakpoint 40181396 and build date April 14, 2004
This bulletin is being revised to add the correct information. Please discard Advanced Services Bulletin Number 04-08-49-017 (Section 8 -- Body & Accessories)
Condition
Some customers may comment that during or after aggressive driving, the engine oil tempature display in the DIC has a higher than expected reading or the oil tempature warning has come on.
Cause
A ground offset between the engine oil tempature sensor and the instrument cluster affects the tempature reading and may indicate a tempature higher than actual. the actual oil tempature should be in operating range.
Correction
Engineering has released a software update. Using normal SPS reprogramming procedures, Technicians are to reprogram the IPC modual wit an updated software calibration. Prior to reprogramming, technicians MUST contact the Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French) to obtain Vehicle COnfiguration INdex (VCI) nymber for assistance in modifying TIS Pass-thru RS-232 Baud rate from 115200 to 57600.
The new calibration will be released beginning with TIS satellite data update version 7.4 to be available on 7-21-04. As always, make sure your TECH2 is updated with the latest software version.
