Instrument Cluster Scan Tool Information
Instrument Panel Cluster Scan Tool Data Parameters
| Parameter | System State | Expected Value | Definition |
|---|---|---|---|
| Operating Conditions: Ignition ON | |||
| Battery Voltage | - | Varies | The scan tool displays 0-19 volts. This is the voltage input supplied to the instrument panel cluster. |
| Engine Coolant Temp | - | Varies | The scan tool displays 38-128°C (100-260°F). The displayed coolant temperature gage value in the IPC. |
| Engine Speed | - | 0 RPM | The scan tool displays 0-9999 RPM. The current engine speed (RPM) signal received by the IPC. |
| PRNDL State | - | The scan tool displays Manual, Low, 2nd, 3rd, Drive, Neutral, Reverse, or Park. The state of the PRNDL indicator as commanded by the IPC. | |
| Fuel Level | - | Varies | The scan tool displays 0-100%. The IPC calculates the amount of fuel remaining in the tank based on the input from the ECM. |
| Trip Odometer | - | Varies | The scan tool displays miles. The IPC calculates trip odometer information from the vehicle speed data received. |
| Trip Reset Switch | - | Inactive | The scan tool displays Active or Inactive. The IPC monitors the control stem on the cluster. A closed switch is displayed as Active. |
| Vehicle Speed | - | 0 mph (0 km/h) | The scan tool displays 0-255 km/h (0-155 mph). The current vehicle speed signal received by the IPC. |
Instrument Panel Cluster Scan Tool Output Controls
| Scan Tool Output Control | Description |
|---|---|
| Coolant Gauge Sweep Test | The instrument panel cluster (IPC) drives the coolant gauge at or below minimum for a few seconds when you select ON, then drives the gauge at or above maximum for a few seconds. The test will end after one cycle of the gauge sweep. |
| Fuel Gauge Sweep Test | The instrument panel cluster (IPC) drives the fuel gauge at or below minimum for a few seconds when you select ON, then drives the gauge at or above maximum for a few seconds. The test will end after one cycle of the gauge sweep. |
| Lamp Test | The IPC illuminates all the indicators when you select On. The indicators should remain illuminated until commanded Off. |
| PRNDL Display | An underscore illuminates under each indicator in the PRNDL display until commanded Off. |
| Speed Gauge Sweep Test | The instrument panel cluster (IPC) drives the speedometer at or below minimum for a few seconds when you select ON, then drives the gauge at or above maximum for a few seconds. The test will end after one cycle of the gauge sweep. |
| Tach Gauge Sweep Test | The instrument panel cluster (IPC) drives the tachometer at or below minimum for a few seconds when you select ON, then drives the gauge at or above maximum for a few seconds. The test will end after one cycle of the gauge sweep. |
