The combination meter assembly and engine oil pressure switch assembly are connected via direct line. The combination meter assembly determines the engine oil pressure based on the engine oil pressure switch signal.
The combination meter assembly receives various signals in order to output warnings from the ECM and hybrid vehicle control ECU via CAN communication.
The combination meter assembly operates the following to output oil pressure warnings:
Engine oil pressure warning buzzer
Engine oil pressure warning message on multi-information display
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
The following troubleshooting procedure is based on the assumption that the SFI system and hybrid control system are normal. Confirm that the SFI system and hybrid control system are not malfunctioning before performing the following procedure.
