This bulletin applies to 2010 Chrysler Town and Country vehicles equipped with a 3.3L engine, equipped with a steering column locking slip collar. A no-start condition, accompanied by inability to remove the key fob, may occur when the battery dies.
New Wireless Ignition Node (WIN) GEN2 uses optical sensors to sense key rotation with bi-stable solenoid to lock the key. The new WIN software fixes mismatch of cryptology handshake between WIN and ESCL, resulting in a SKIM out.
Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, first verify that all engine systems are functioning as designed.
Replace the WIN following the detailed service procedures in DealerCONNECT/TechCONNECT. Refer to Group 8 – Electrical > Electronic Control Modules 8E > Receiver, Wireless Ignition Node.
A replacement WIN is available as P/N 68210155AA.
