Circuit Operation

Engine Coolant Temperature Gauge
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gauge defaults to 100 °F (40 °C) or below if:
1. The PCM detects a malfunction in the engine coolant temperature sensor circuit.
2. The IPC detects a loss of class 2 communications with the PCM.

Engine Oil Pressure Gauge
The IPC displays the engine oil pressure as determined by the PCM. The IPC receives aclass2 message from the PCM indicating the engine oil pressure. The engine oil pressure gauge defaults to 0 psi (0 kPa) or below if:
1. The PCM detects a malfunction in the engine oil pressure sensor circuit.
2. The IPC detects a loss of class 2 communications with the PCM.

Fuel Gauge
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from thePCM indicating the fuel level percent. The fuel gauge defaults to empty if:
1. The PCM detects a malfunction in the fuel level sensor circuit.
2. The IPC detects a loss of class 2 communications with the PCM.

When the fuel level is less than a pre-determined value, the IPC illuminates the low fuel indicator.

Odometer
The base IPC contains a season odometer and a trip odometer. The up level IPC contains a season odometer and two trip odometers. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer.
