A WORD ABOUT YOUR KEYS
Your vehicle uses either a key start ignition system or
keyless ignition system. The key start ignition system
consists of a either a bladed key with an immobilizer chip
in it, or a Key Fob with Remote Keyless Entry (RKE)
transmitter and an Ignition Node Module (IGNM). The
keyless ignition system consists of a Key Fob with
Remote Keyless Entry (RKE) transmitter and a Keyless
Ignition Node (KIN).
Ignition Node Module (IGNM)
The Ignition Node Module (IGNM) operates similar to an
ignition switch. It has four operating positions, three with
detents and one that is spring-loaded. The detent posi-
tions are OFF, ACC, and ON/RUN. The START position
is a spring-loaded momentary contact position. When
released from the START position, the switch automati-
cally returns to the ON/RUN position.
