 CLAMP stands for Courtesy lamp The radio is back feeding thru another circuit when you shut it off very common.


   If you had any work done latly I would look there first for loose or freyed wires.Bad grounds ect.

WHAT ABOUT A BAD RELAY..........A BAD DOOR JAM SWITCH?????
Expert:  Davo replied 11 years ago.
Cause: Clamp 15A, fuse #10, 10 amp fuse blown to the BCM/PZM, terminal A11. This fuse is normally powered in run and not during cranking. When this fuse is blown, the BCM acts as though it is in the crank mode with the key on. The BCM turns the radio off via CLASS 2 and inhibits auto door lock operation. The HVAC control head inhibits a/c compressor operation.

CORRECTION:

Replace the 10 amp #10 fuse.
Check the heater water pump located at the right wheel well area for a leak. Also, check the auxiliary pump located on the left side of the radiator support for a leak. If either pump is leaking, coolant may be dripping onto a connector for this fused circuit which may cause a short to ground condition.
If both pumps are okay, install in-line fuses rated less then the fuse in question for each component affected to isolate the failed circuit.
Please follow this diagnosis process thoroughly and complete each step.

Expert:  Davo replied 11 years ago.
No coolant leakage from either pump?Have you run it and checked for leaks or pressure tested it?Be aware if coolant is still laying in a connector it can still blow a fuse.So you should try to clean the connections with a solvent like brake clean and blow dry them with compressed air if possible.Take the connections apart to clean and then snap them back together.Keep me advised.
