REMOVAL
1. Disconnect and isolate the negative battery cable(s) (Refer to 08 - Electrical/Battery System/Standard Procedure) .
2. Remove the sport bar speaker pod assembly (Refer to 08 - Electrical/8A - Audio and Video/ENCLOSURE, Speaker/Removal and Installation) .
3. Disconnect the wire harness connector.
4. Remove the antenna mounting retainer.
5. From inside the vehicle, using a flat bladed tool, press one of the two plastic retaining tabs on the antenna
stud. Push up on one side of the antenna stud, press the other plastic retaining tab and remove the antenna
from the sport bar.
INSTALLATION
Follow the removal procedure in reverse for general reassembly of the components on the vehicle. The steps listed below are calling out specific procedures that
should be followed during installation.
A new silver clip (with four legs) must be used if the same antenna is being re-installed.
Insert the wire harness through the hole in sport bar. Press the antenna into position until both retainers on the antenna stud and the locator stud engage into
position in the sport bar.
Tighten the fastener securely.
08 - Electrical / 8A - Audio/Video/Entertainment/Connectivity / BODY AND CABLE, Antenna / Diagnosis and Testing
DIAGNOSIS AND TESTING - ANTENNA BODY AND CABLE
The following four tests are used to diagnose the antenna with an ohmmeter:
TEST 1 – Mast to ground test
TEST 2 – Tip-of-mast to tip-of-conductor test
TEST 3 – Body ground to battery ground test
TEST 4 – Body ground to antenna coaxial cable shield test.
WARNING:
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before
attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or
instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly
from the negative battery post, then wait two minutes for the system capacitor to discharge before performing further diagnosis or
service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag
deployment.
The ohmmeter test lead connections for each test are shown in the illustration.
NOTE:
This vehicle has a two-piece radio antenna coaxial cable. Tests 2 and 4 must be conducted in two steps to isolate an antenna cable
problem. First, test the primary antenna cable (located between the antenna body and the secondary cable) from the coaxial cable
connector under the right end of the instrument panel near the right cowl side inner panel to the antenna body. Then, test the secondary
antenna cable (instrument panel antenna cable) from the coaxial cable connector under the right end of the instrument panel near the
right cowl side inner panel to the coaxial cable connector at the radio.
TEST 1 – Test 1 determines if the antenna mast is insulated from ground. Proceed as follows:
1. Disconnect and isolate the antenna coaxial cable connector under the right end of the instrument panel near
the right cowl side inner panel.
2. Touch one ohmmeter test lead to the tip of the antenna mast. Touch the other test lead to the antenna body.
Check the ohmmeter reading for continuity.
3. There should be no continuity. If OK, go to Test 2. If not OK, replace the shorted antenna body and cable.
TEST 2 – Test 2 checks the antenna conductor components for an open circuit. This test should be performed first
on the entire antenna circuit, from the antenna mast to the center conductor of the coaxial cable connector at the
radio. If an open circuit is detected, each of the three antenna conductor components (antenna mast, antenna
body and primary cable unit, instrument panel antenna secondary cable) should be isolated and tested
individually to locate the exact component that is the source of the open circuit. To begin this test, proceed as
follows:
1. Disconnect the instrument panel (secondary) antenna cable coaxial connector from the back of the radio.
2. Touch one ohmmeter test lead to the tip of the antenna mast. Touch the other test lead to the center
conductor pin of the instrument panel antenna cable coaxial connector for the radio. Check the ohmmeter
reading for continuity.
3. There should be continuity. The ohmmeter should register only a fraction of an ohm resistance. High or
infinite resistance indicates a damaged or open antenna conductor. If OK, go to Test 3. If not OK, isolate and test each of the individual antenna conductor
components. Replace only the ineffective antenna conductor component.
TEST 3 – Test 3 checks the condition of the vehicle body ground connection. To begin this test, proceed as follows:
1. This test must be performed with the battery positive cable disconnected from the battery. Disconnect and isolate both battery cables, negative cable first.
2. Reconnect the battery negative cable.
3. Touch one ohmmeter test lead to a good clean ground point on the vehicle right fender panel. Touch the other test lead to the battery negative terminal post.
Check the ohmmeter reading for continuity.
4. There should be continuity. The ohmmeter should register less than one ohm resistance. High or infinite resistance indicates a loose, corroded or damaged
connection between the battery negative terminal and the vehicle body. If OK, go to Test 4. If not OK, check the battery negative cable connection to the
vehicle body and the radio noise suppression ground strap connections to the engine and the vehicle body for being loose or corroded. Clean or tighten these
connections as required.
TEST 4 – Test 4 checks the condition of the connection between the antenna coaxial cable shield and the vehicle body ground as follows:
1. Disconnect and isolate the antenna coaxial cable connector under the right end of the instrument panel near the right cowl side inner panel.
2. Touch one ohmmeter test lead to a good clean ground point on the vehicle right fender panel. Touch the other test lead to the outer crimp on the antenna
coaxial cable connector under the right end of the instrument panel near the right cowl side inner panel. Check the ohmmeter reading for continuity.
3. There should be continuity. The ohmmeter should register less than one ohm resistance. High or infinite resistance indicates a loose, corroded or damaged
connection between the antenna body and the vehicle body or between the antenna body and the antenna coaxial cable shield. If not OK, clean the antenna
body to right fender panel mating surfaces and tighten the antenna mounting nut to specifications.
4. Check the resistance again with an ohmmeter. If the resistance is still more then one ohm, replace the ineffective antenna body and cable.
For additional diagnosis of an AM/FM reception issue, perform the POOR OR NO AM/FM AUDIO RECEPTION test. (Refer to 29 - Non-DTC
Diagnostics/Audio/Video/Diagnosis and Testing) .
