Condition
Some customers may comment on a dead battery after the vehicle has been parked for a extended period of time.
Typically, the battery will last approximately two weeks, depending on the initial state of battery charge.
Cause
A software anomaly within the remote control door lock receiver (RCDLR) causes an additional 30 mA draw on the battery when passive locking is
enabled and the vehicle is parked.
Correction
Use the Pass-Thru method when programming and select "Replace and Reprogram ECU."
A new calibration has been released to correct this condition. Reprogram the RCDLR using SPS. This new service calibration is available on TIS2WEB.
On Corvette models, prior to reprogramming, remove the Radio/S-Band/VICS 15-amp fuse and the HVAC/PWR SND 10-amp fuse from the I/P
electrical center (passenger floor). Also, the ignition must be in the "Key On Engine Off" mode.
If the programming does not finish successfully and the RCDLR appears to be in a "locked-up" state, DO NOT turn off the ignition, it can be reset by
removing the RCDLR fuse (# 11 in the UBEC) for at least 30 seconds and reinstalling it. If the ignition was turned to OFF after the "locked up"
condition occurred, its possible to continue programming by adding the VIN manually in TIS.
Tip
Transmitter programming and tire pressure learn procedures are NOT necessary after this reprogram.
