Refer to Wiring Diagrams Cell 20 for schematic and connector information.

Normal Operation and Fault Conditions


REFER to: Steering Wheel and Column Electrical Components - System Operation and Component Description (211-05 Steering Wheel and Column Electrical Components, Description and Operation).

The push-button ignition switch is a momentary, dual-contact, normally-open switch. The push-button ignition switch inputs are monitored by the RFA module by 2 circuits. When the START/STOP button is pressed, both contacts close and both voltage signals are routed to ground. The 2 circuits are for redundancy. If there is a concern with one of the 2 inputs, the other input provides a ground signal to allow the vehicle to start and a DTC sets.


  RFA Module DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B108B:23 Start Button Circuit "A": Signal Stuck Low Pressing the start/stop switch starts a 120 second timer in the RFA module. This DTC sets when the RFA module detects the signal from C3503B-23 is still pulled low (switched to ground) when the timer expires. Holding the start/stop button pressed for more than 120 seconds can cause this DTC to set. This DTC only sets continuous; not during a module self-test.
B108B:29 Start Button Circuit "A": Signal Invalid When RFA module detects 5 occurrences of the push-button start ignition switch inputs not corresponding to each other, such as an open in one of the input circuits, this DTC sets. This DTC only sets continuous; not during a module self-test.
B108C:23 Start Button Circuit "B": Signal Stuck Low Pressing the start/stop switch starts a 120 second timer in the RFA module. This DTC sets when the RFA module detects the signal from C3503B-22 is still pulled low (switched to ground) when the timer expires. Holding the start/stop button pressed for more than 120 seconds can cause this DTC to set. This DTC only sets continuous; not during a module self-test.

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.
