Push-Button Start System
The START/STOP button (ignition switch) is used to control the ON, OFF and START ignition modes.
The RFA module sends 2 voltage signals to the push-button ignition switch to monitor requests to turn the ignition on, off or to start the vehicle. When the button is pressed, the voltage signals are routed to ground indicating a request to change the ignition state. Changing the ignition state from the OFF mode works in conjunction with the PATS . A programmed key is required to change the ignition from OFF to ON. For additional PATS information, Refer to: PASSIVE ANTI-THEFT SYSTEM (PATS) - SYSTEM OPERATION AND COMPONENT DESCRIPTION .
The RFA module provides voltage to the same circuits a conventional ignition switch does by using additional relays to achieve 2 of the 3 standard ignition states (ON and START). Unlike a conventional ignition switch system, the pushbutton start system does not have an ACC mode. The RFA module only utilizes the OFF, ON and START modes.
Refer to the following chart for information about achieving the various ignition states.
| Ignition Entry Condition | Desired Ignition Mode | Action To Take |
|---|---|---|
| Off | ON (engine off) | Press the START/STOP button without applying the clutch pedal (manual transmission) or the brake pedal (automatic transmission). |
| Any ignition mode | START | Apply and hold the clutch pedal (manual transmission) or the brake pedal (automatic transmission) and then press the START/STOP button. |
| On (engine off) | OFF | Press the START/STOP button. |
| On (engine running) | OFF | Press and hold the START/STOP button. |
The RFA module must recognize a programmed key before it changes the ignition state from OFF.
