P311 HYBRID TRANSMISSION / TRANSAXLE: ELECTRONIC SHIFT LEVER SYSTEM: C2315: HV System
C2315 - HV System

DESCRIPTION

The transmission control ECU receives a P position switch signal from the hybrid vehicle control ECU and activates the parking lock motor by controlling current, causing the parking lock mechanism to switch. When the hybrid vehicle control ECU detects a malfunction with the P position switch or P position signal, it sends an information signal to the transmission control ECU. After receiving this signal, the transmission control ECU outputs this DTC.
