cruise control not ready

[tyrone]

I was doing my usual trip thru Idaho and Montana last week, using my cruise control most of the time . After I stop and tried to use my cruise, I got a message on the DIC that said "cruise control not ready". Never seen that one before. Waited 30 seconds and tried it again, same message. Waited around 5 minutes and everything was good to go. Message never reappeared. Anyone ever experience such a message before or know what happened?

Actually happens to me quite often... not sure why, but, as you say, wait about 5 minutes and all is well.

CRUISE NOT READY

The DSCC commands the display of the CRUISE NOT READY message in the DIC when ACC cannot engage due to a temporary condition. The ACC vehicle conditions that prompt the display of the CRUISE NOT READY message are temporary and do not require service. If no target is identified by the forward looking sensor (FLS) and cruise is attempted to be engaged, the CRUISE NOT READY message will be displayed in the DIC until the FLS is able to identify an accepted target. CRUISE NOT READY message is also displayed in the DIC when the DSCC is too hot and the brakes are too hot. The DIC sounds an internal chime anytime it displays the CRUISE NOT READY message.

Could it also be due to a dirty lens, or does the DIC display that message??

CLEAN RADAR

The CLEAN RADAR message displays in the DIC when the DSCC detects a blockage of the FLS and cruise is engaged or attempted to be engaged. The FLS may be blocked by snow, ice, dirt, heavy rain or road spray. The DSCC commands the display of the CLEAN RADAR message via a GMLAN serial data circuit request to the BCM. The DIC displays the CLEAN RADAR message when it receives a class 2 serial data request from the BCM. When the CLEAN RADAR message is displayed in the DIC, safely park the vehicle and turn OFF the ignition. Clean the driver side front fascia lens to eliminate the blockage. It may be necessary to clean both the outside surface of the lens, the inside surface of the lens and the DSCC surface. Refer to Distance Sensing Cruise Control Maintenance for more cleaning information. It is important to turn the ignition OFF before cleaning any of the named surfaces. This is because the CLEAN RADAR message may still display in the DIC after cleaning the 3 surfaces. Cycling the ignition to OFF for 10 seconds is necessary to clear the CLEAN RADAR indicator if the indicator remains ON in the DIC. The DIC sounds an internal chime anytime it displays the CLEAN RADAR message. In rare instances, the target characteristics or a vertically misaligned FLS may trigger the activation of the CLEAN RADAR message in the DIC. Refer to Distance Sensing Cruise Control Aiming .

This is great stuff. While on my recent trip to/from northern Minnesota, my ACC would sometimes interpret an overpass as a stopped car! Lights, brakes, etc., and a hazard to the car behind me and to myself. Once past the bridge, all was well.

I would love to have referred to that link you provided, Bruce, but I get a "Page Not Found" message. Wonder if it got left behind when we changed servers.

[/TD]
[TD]For horizontal adjustment, measure the back of the horizontal adjuster. Adjust the horizontal until 6 mm (0.25 in) of the adjuster is protruding out behind the radar. This method should work assuming that the bracket and frame have not been damaged in a collision.

[TABLE="align: center"]
<TBODY>[TR]
[TD]3.
[/TD]
[TD]Use a scan tool to perform a Factory Reset of the adaptive cruise module (ACM). Ensure that the Auto Alignment Learn Status parameter indicates Not Aligned. This allows the forward looking sensor (FLS) to automatically align itself during vehicle driving.

</TBODY>[/TABLE]

[TABLE="align: center"]
<TBODY>[TR]
[TD]4.
[/TD]
[TD]Drive the vehicle at speeds of at least 56 kph (35 mph), so that the automatic alignment process can operate. The process requires the radar to observe stationary targets along the edge of the road (i.e. mail boxes, parked cars, poles, signs, etc.). Do not follow other vehicles too closely, since this obscures the view for the radar.

[/TD]
[TD]Use a scan tool to monitor the Auto Alignment Learn Status parameter. Continue driving until the Auto Alignment Learn Status parameter indicates Aligned. Typically, it will require less than 10 miles of driving. If not proceed to step #4. If the resulting Alignment Error is within -1.5 and 1.5 degrees, the alignment is within specification. Otherwise, proceed to step #6.

cruise control

Will I get a "smuched grasshopper" message?

 

[BoughtTheXLR]

Re: Distance Sensing Cruise Control Aiming

Shouldn't the first step be to ensure that the car itself is level? If it isn't then the vertical adjustment would be incorrect...

 

[Crimson Pearl]

Bruce,

Your everyday Clark Kent persona is stripped away to reveal our XLR Supertech!

Another reason we all love ya!

We have ALL learned so much reading these threads.

 

[XFireXLR]

Never got that message, but got a "Disk Not Ready" audible message when trying to use the voice command option. I was not able to use the voice command option until I restarted the car. This has never happened before, and has not happened since.
