Problem - Cruise control SET light blinks continously
hey guys i have a issues with my 05 350z. When i turn on cruise control, the SET light keeps blinking. And the cruise control never engages. The issue only occurs sometimes.
SET only blinks when i turn on cruise control.
Got this from google:
When the ECM detects any of the following conditions, the ECM will cancel the cruise operation and inform the driver by blinking indicator lamp.
Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE lamp may blink slowly.
When the engine coolant temperature decreases to the normal operating temperature, CRUISE lamp will stop blinking and the cruise operation will be able to work by pressing SET/COAST switch or RESUME/ACCELERATE switch.
Malfunction for some self-diagnoses regarding ASCD control: SET lamp will blink quickly.
So im guessing its the last one. SET lamp blinks continously.
I've noticed the issue does not happen on cold days (even if i drive the car hard). The issue does happen more on hot days. And if i turn off the car and on after a while, the issue is gone. So i'm guessin its something to do with temperature?
Any ideas guys on the issue?

actually scratch that. I started after coming back from work and the issue happend within 5 minutes. So I doubt its to do with heat.

This all links back to the clutch pedal (microswitch):
Faulty microswitch = no start, as the clutch needs to be depressed.
Faultly microswitch = flashing cruise light, as the clutch is part of the cruise system.

Noticed following behaviour...
* start the car, press cruise control on/off button, CRUISE light turns on. SET is not blinking. CRUISE stays on, and i can use cruise control by pressing SET. I can se cruise control like this for a long time.
* But, once i turn off cruise control via the button, CRUISE light turns off, SET turns off. When I drive like this for 3-5 minutes, turn cruise control on, the CRUISE light comes on, but the SET light keeps blinking. Turn off cruise, SET stops blinking. SET only blinks when cruise is on.
* The only way to fix the issue is to pull over, stop the car, and restart it, and i can start using cruise again.
Any idea what the issue is guys?

Same problem
I have the same problem. Ounce set light flashes, the cruise fails to work. The only way to"reboot" cruise is to turn engine off and restart. Mine also fails sometimes when cruising.

Blinking cruise control "set" light.

It could be a number of things. The Automatic Speed Control Device (ASCD) or "cruise control" operates based on various input to the ECM. Here's a breakdown from the FSM. If your coolant temp is good, it may be one of the switches/sensors or the ECM (hopefully not).
You can try cleaning the contacts for the pedals first since that seems to be the easiest. Here's a link to a DIY: https://my350z.com/forum/engine-driv...nd-adjust.html
Good luck!
