On occation on my overhead display it will show CCD. From a search it appears to be Chrysler's Collision Detection. Not sure what it means or how to get rid of it. Also on occation my display will dim at random without me even touching it as I drive down the road. Anyone have any experience with this or advice on how to clear this?


Thanks

 

I have CCD appearing as well, and have heard that the overhead module can fail and display that. When I first got the truck it had CCD, I unplugged the module and it went away, for a while. It is back again, and I have been unable to clear it in anyway.

Found this on the net:
This is out of the 2001 service manual. It may help you find out whats up.

SELF-DIAGNOSTIC TEST
A self-diagnostic test is used to determine that the
compass mini-trip computer module is operating
properly electrically. Initiate the self-diagnostic test
as follows:
(1) With the ignition switch in the Off position,
simultaneously depress and hold the Step button and
the U.S./Metric button.
(2) Turn the ignition switch to the On position.
(3) Continue to hold both buttons depressed until
the compass mini-trip computer module enters the
display segment test. In this test, all of the Vacuum
Fluorescent Display (VFD) segments are lighted
while the compass mini-trip computer module performs
the following checks:
² Microprocessor RAM read/write test
² Non-volatile memory read/write test
² Microprocessor ROM verification test
² CCD communications test.
(4) Following completion of these tests, the compass
mini-trip computer will display one of three
messages: “PASS,” “FAIL,” or “CCd.” Respond to the
respective test results as follows:
² If the “PASS” message is displayed, but compass
mini-trip computer operation is still improper, the
use of a DRB scan tool and the proper Diagnostic
Procedures manual are required for further diagnosis.
² If the “FAIL” message is displayed, the compass
mini-trip computer module is faulty and must be
replaced.
² If the “CCd” message is displayed, the use of a
DRBt scan tool and the proper Diagnostic Procedures
manual are required for further diagnosis.
² If any VFD segment should fail to light during
the display segment test, the compass mini-trip computer
module is faulty and must be replaced.
(5) If all tests are passed, or if the ignition switch
is turned to the Off position, the compass mini-trip
computer module will automatically return to normal
operation.

 

Thanks I will give it a shot. If the module is faulty do you know of any places to get them besides the dealer?

 

Unfortunately I do not, I believe I will be looking for one myself soon. Auto Wreckers I suppose.

 

I have tested mine a few times over the last while. Still just shows CCd. Sure wish the dealerships up here could free up 20 minutes for a guy. They want me to leave the truck there ALL DAY! I know at our shop we do quick little scans for customers, good way to keep your customer happy.
