No, does not have an adaptive cruise.
The scan tool does show that PCM registers which button is pressed. The switch is a simple multiplexed switch with a resistor network that passes data through LIN. My understanding is that if PCM and SAS modules can see which cruise control button is pressed they should trigger it.
The brake (or stop) lamp switch controls three independent circuits. These circuits are described as follows:
•Brake Lamp Switch Circuit - A normally open brake lamp switch circuit receives a battery voltage input, and supplies this battery voltage to the Center High Mounted Stop Lamp (CHMSL) and the Totallly Integrated Power Module (TIPM) on a brake lamp switch output circuit only when the brake pedal is depressed (brake lamp switch plunger released).
•Brake Lamp Switch Signal Circuit - A normally closed brake lamp switch signal circuit receives a direct path to ground, and supplies this ground input to the Powertrain Control Module (PCM) on a brake signal 1 circuit only when the brake pedal is released (brake lamp switch plunger is depressed).
•Speed Control Circuit - A normally closed speed control circuit receives a battery voltage input from the Totallly Integrated Power Module (TIPM) on an ignition run/start control output circuit, and supplies this battery voltage to the PCM on a brake signal 2 circuit only when the brake pedal is released (brake lamp switch plunger is depressed).
The PCM sends electronic brake lamp switch status messages to other electronic modules in the vehicle over the Controller Area Network (CAN) data bus for use as an additional logic input for controlling many other vehicle functions and features.
Interestingly if you see my scanner showed the clutch pedal as pressed. The car is auto and I think the scanner is showing signal 1 or 2 as clutch. If its pressed the cruise will not turn on I guess. I have ordered the brake switch because it was 33 bucks oem. Too bad that I can't find the CRD ECU diagram to trace those signals.
