Instrument Cluster (IC) Prove-Out
The instrument cluster (IC) and other vehicle modules carry out a display prove-out to verify that all module controlled warning/indicator lamps and monitored systems are functioning correctly within the instrument cluster (IC). When the ignition switch is cycled to the ON position with the engine off, the indicators illuminate to prove-out according the following table:
| Indicator | Controlling Module | Indicator Type | Prove-Out Duration |
|---|---|---|---|
| Air bag | Restraints control module (RCM) | Warning | 6 seconds |
| ABS | Instrument cluster (IC) | Warning | 3 seconds |
| Anti-theft indicator | Instrument cluster (IC) | Indicator | 3 seconds |
| Brake | Instrument cluster (IC) | Warning | 3 seconds |
| Malfunction indicator lamp (MIL) | PCM | Warning | Engine startup |
| Safety belt | RCM | Warning | 65 seconds if the safety belt is unbuckled, turns off when the safety belt is buckled |
| Speed control | PCM | Indicator | No prove-out |
| Tire pressure monitoring system (TPMS) | Instrument cluster (IC) | Warning | 3 seconds |
| High beam | Instrument cluster (IC) | Indicator | No prove-out |
| Overdrive off | Transmission control module (TCM) | Indicator | No prove-out |
| RH/LH turn signals | Instrument cluster (IC) | Indicator | No prove-out |
