U300E:62, U300F:62, U300F:00, U3010:62 or U3011:62


Refer to Wiring Diagrams Cell 13 for schematic and connector information.

Normal Operation and Fault Conditions

The RFA module monitors the push-button ignition switch. When the START/STOP button is pressed, the RFA module changes the ignition state (OFF to ON or ON to OFF). After receiving this input, the RFA module activates/deactivates the smart keyless entry ignition relay and the smart keyless entry accessory relay.

The IPC receives voltage input on separate circuits from the 2 smart keyless entry relays. Based on the input, the IPC sends an ignition status message to the RFA module over the CAN . The RFA module compares its current ignition state with the ignition status data from the IPC . If a discrepancy exists, a DTC sets.
