PTC Compromised Rod Detection

Checks for inoperative Positive Temperature Coefficient (PTC) heater rods and stores the result in the Right Vehicle Controller (VCRIGHT) ECU. Allows the VCRIGHT to restore operation of the PTC heater by not turning on the inoperative rod. To clear the stored information in VCRIGHT, run this routine if the PTC heater is replaced.
