Normal Operation
To place the vehicle in ON mode, place the Intelligent Access (IA) key inside the vehicle and press the start/stop switch for at least one second without applying the brake pedal (or clutch pedal if equipped with a manual transmission). When in ON mode, the Remote Function Actuator (RFA) module applies battery voltage to the coil side of the smart keyless entry ignition relay and the smart keyless entry accessory relay. When activated, the smart keyless entry ignition relay provides battery voltage to the main ignition relay and several fuses in the Central Junction Box (CJB). The main ignition relay provides power to various vehicle systems. When activated, the smart keyless entry accessory relay provides battery voltage to CJB (Central Junction Box) fuses 19 (7.5A) and 26 (7.5A).
To start the engine; place the IA (Intelligent Access) key inside the vehicle, shift the transaxle into PARK (automatic transaxle) or NEUTRAL (automatic or manual transaxle), place the vehicle in either OFF mode or ON mode, press and hold the brake pedal (automatic transaxle) or clutch pedal (manual transaxle), then press the start/stop switch.
At that time, the RFA (Remote Function Actuator) module sends a voltage signal to the input side of the starter inhibit relay coil. If the Passive Anti-Theft System (PATS) authorizes the system to start the engine, the PCM supplies a ground to the coil of the starter inhibit relay, closing the relay and engaging the starter motor.
In the event the vehicle will not enter ON or START mode, the Front Control/Display Interface Module (FCDIM) displays messages that may indicate possible causes.
This pinpoint test is intended to diagnose the following:
- Fuses
- Wiring, terminals or connectors
- Start/stop switch
- Smart keyless entry ignition relay
- Smart keyless entry accessory relay
- Ignition relay
- Cruise control deactivation switch
- Clutch Pedal Position (CPP) switch
- Starting system
- PATS (Passive Anti-Theft System)
- RFA (Remote Function Actuator) module
