DTC B2502, Park Relay (BTSI) Shorted To Ground: Notes

When transaxle is in Park, PZM controls park relay output low to enable Brake Transaxle Shift Interlock (BTSI). PZM will continuously monitor this voltage. DTC B2502 will set when park relay output is not active, IGN-1 input exists, and PZM determines output is low for 2 consecutive monitoring cycles. DTC B2502 will clear when park relay output is not active, IGN-1 input exists, and PZM determines output is high for one monitoring cycle.
