With Conventional Instrument Cluster
The instrument cluster system consists of the following components:
- Tachometer
- Speedometer
- Fuel gauge
- Instrument cluster gauge amplifier
- Engine coolant temperature gauge
- Vehicle odometer
- Trip odometer
- A transmission range indicator
- An odometer reset shaft
The instrument cluster contains the following indicators and warning indicators:
- Charging system
- Safety belt
- BRAKES
- High beams
- Low oil pressure indicators
- Left turn / right turn signal
- LOW COOLANT
- Low fuel
- SERVICE ENGINE SOON (Malfunction Indicator Lamp. MIL)
- Anti-Lock Brake System (ABS)
- Air bag
- Door ajar
- Low washer fluid
- CRUISE
- Transmission control indicator (O/D OFF)
- THEFT (alarm status)
- Traction assist
Instrument Cluster Display Prove Out
When the ignition switch is turned to RUN, the following warning lamps will prove out by momentarily lighting:
- SERVICE ENGINE SOON
- Safety belt
- Charging system
- Air bag
- Low oil pressure
- Anti-lock brake system
- Door ajar
- Low fuel
Printed Circuit
The instrument cluster printed circuit :
- Supplies current to the instrument cluster lamps and gauges.
- Is made of copper foil which is bonded to a polyester base film (usually referred to as Mylar).
- Is mounted to the instrument cluster housing. Due to its location, the instrument cluster printed circuit cannot be easily inspected and/or tested in the vehicle. This makes the instrument cluster printed circuit vulnerable to damage when a probe is used for in-vehicle testing. The probe can pierce the instrument cluster printed circuit or in some cases, burn the copper conductor.
