DTC B2477: Reverse Light Relay Shorted To Ground: Description

When PZM receives input that transaxle is in reverse, PZM energizes reverse light relay which will turn on back-up lights. When back-up lights have been commanded on, PZM constantly measures voltage at Brown 32-pin connector C2, terminal D14 (Dark Green wire). DTC B2477 will set when voltage is approximately equal to ground. DTC B2477 will clear when voltage is greater than ground for at least one monitoring cycle.
