Dodge Nitro. Manual - part 307

DIAGNOSIS AND TESTING 

SPEAKER 

Any diagnosis of the Audio system should begin with the use of scan tool. For information on the use of 
the scan tool, refer to the appropriate Diagnostic information.  

Refer to the appropriate wiring information. 

1. If all speakers are inoperative, check the fuses in the Totally Integrated Power Module (TIPM). If OK, go 

to Step 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse.  

2. Turn the ignition switch to the ON position. Turn the radio receiver ON. Adjust the balance and fader 

control controls to check the performance of each individual speaker. Note the speaker locations that are 
not performing correctly. Go to Step 3.  

3. Turn the radio receiver OFF. Turn the ignition OFF. Disconnect and isolate the battery negative cable. If 

vehicle is not equipped with an amplifier, remove the radio receiver. If vehicle is equipped with an 
amplifier, disconnect wire harness connector at output side of amplifier. Go to Step 4.  

4. Check both the speaker feed (+) circuit and return (-) circuit cavities for the inoperative speaker at the 

radio receiver wire harness connector for continuity to ground. There should be no continuity. If OK, go 
to Step 5. If not OK, repair the shorted speaker feed (+) and/or return (-) circuits(s) to the speaker as 
required.  

5. Disconnect wire harness connector at the inoperative speaker. Check for continuity between the speaker 

feed (+) circuit cavities of the radio receiver wire harness connector and the speaker wire harness 
connector. Repeat the check between the speaker return (-) circuit cavities of the radio receiver wire 
harness connector and the speaker wire harness connector. In each case, there should be continuity. If 
OK, replace the faulty speaker. If not OK, repair the open speaker feed (+) and/or return (-) circuits(s) as 
required.  

WARNING:

Disable the airbag system before attempting any steering wheel, steering 
column, seat belt tensioner, side airbag, or instrument panel component 
diagnosis or service. Disconnect and isolate the battery negative (ground) 
cable, then wait two minutes for the airbag system capacitor to discharge 
before performing further diagnosis or service. This is the only sure way 
to disable the airbag system. Failure to take the proper precautions could 
result in accidental airbag deployment and possible personal injury.

CAUTION: The speaker output of the radio is a "floating ground" system. Do not 

allow any speaker lead to short to ground, as damage to the radio may 
result.

NOTE:

If poor sound quality is noted in the audio system, check the Cabin Equalization 
curve programmed in the TIPM. Make sure a base speaker system has the Base 
Cabin Equalization Curve programmed to the vehicle. If the vehicle has a 
premium speaker system, make sure the Premium Cabin Equalization Curve is 
programmed to the vehicle
