Cruise Control Indicator Always On

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

Circuit/System Description

The powertrain control module (PCM) monitors the cruise control indicator switch. When the cruise on/off switch is switched ON, the cruise control switch is closed and the signal circuit is high. When the cruise on/off switch is switched OFF, the cruise control switch is open and the signal circuit is low.

Circuit/System Verification

1. Ignition ON, verify that the Cruise Lamp parameter in the instrument panel cluster (IPC) inputs reads On.

• If the parameter displays Off, replace the IPC.

2. Observe the Cruise Control Active parameter in the PCM.

• If the parameter reads Off, replace the IPC.
• If the parameter displays On, replace the PCM.
