OIL TEMPERATURE WARNING DEVICE OF AUTOMATIC VEHICLE

摘要

PURPOSE: To reduce the number of parts and manufacturing cost by eliminating an oil temperature warning lamp. CONSTITUTION: Oil temperature warning is done by flashing an N range lamp 17 by way of doubly using the N range lamp 17 of a shift indicator to indicate a shift range position and controlling a switching cycle of a switching transistor 26 by an N range lamp signal output circuit 24 against an oil temperature warning signal output from a CPU 23. Additionally, the N range lamp 17 is also doubly used for failure warning indication, and the N range lamp signal output circuit 24 flashes the N range lamp 17 at the time of failure warning and oil temperature warning by way of changing the cycle and carries out failure indication preferentially.
