P0603= VCM memory reset(could be set by disconnecting the battery)
C1762= Left rear position sensor input fault
B1552= Loss of BCM keep alive memory(could also be set by disconnecting the battery)
As far as the C1762, first check to see the the connector for the LR sensor is plugged in correctly, and is not corroded. From there, the service manual can help with the diagnostics, if you have it. If not, then first check the connector, and post back. The sensors seem to have a problem with the connectors, as well as water intrusion.
