Section 495 (Speed Control): Switch: Description

WARNING: This page is about a different car, the 2005 Dodge Pickup and 2005 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Two separate switch pods operate the speed control system. The steering-wheel-mounted switches use multiplexed circuits to provide inputs to the PCM (to the ECM for diesel) for ON, OFF, RESUME, ACCELERATE, SET, DECEL and CANCEL modes. Refer to the owner's manual for more information on speed control switch functions and setting procedures.

The individual switches cannot be repaired. If one switch fails, the entire switch module must be replaced.

Depending on engine control computer (JTEC having a 3- plug connector or NGC having a 4- plug connector), 2 types of switches are used. Both types of switches are internally and externally different. The switch used with the NGC system (3.7L, 4.7L, 5.7L) has an attached pigtail lead. The switch used with the JTEC system (8.3L SRT-10) does not have an attached pigtail lead.
