Pinpoint Test B : The Satellite Radio Is Inoperative, Has Poor Reception Or No Sound

B1 CHECK THE ACM DTCs

Using a diagnostic scan tool, clear the ACM DTCs.

Repeat the ACM self-test.

Are any DTCs present?

Yes	If DTC B1A89:11 or DTC B1A89:13 is present, GO to B3. If DTC U3000:96 is present, INSTALL a new ACM. Refer to Audio Control Module (ACM) . For all other DTCs. Refer to DTC chart .
No	GO to B2.

B2 CHECK THE RECEPTION AND CATEGORY FILTER SETTING

Turn the category filter function off. Refer to the Owner's Literature.

Drive the vehicle to an open location, free of obstacles.

Scan for a good channel.

Does the satellite audio system find a good channel with normal reception?

Yes	The system is operating correctly at this time. The concern was a result of no channel being found in the selected category or obstructions to the antenna line of sight.
No	GO to B3.

B3 CHECK THE SATELLITE RADIO ANTENNA CABLE RESISTANCE

Ignition OFF.

Disconnect: Satellite Radio Antenna Connection at the ACM.

Disconnect: Satellite Radio Antenna Cable In-Line Connection at the RH Scuff Plate Trim Panel.

Disconnect: Satellite Radio Antenna Connection at the Satellite Radio Antenna.

Measure the resistance of the upper satellite radio antenna cable core between the satellite radio antenna and the satellite radio antenna in-line connection; and between the upper satellite radio antenna cable core and shield.

Measure the resistance of the lower satellite radio antenna cable core between the ACM and the satellite radio antenna in-line connection; and between the lower satellite radio antenna cable core and shield.

Is the resistance of each satellite radio antenna cable core less than 1 ohm, and the resistance between the core and shield of each satellite radio antenna cable more than 10, 000 ohms?

Yes	GO to B4.
No	INSTALL a new satellite radio antenna cable, as necessary. Refer to Antenna Cable - Front or Antenna Cable - Rear .

B4 ISOLATE THE SATELLITE RADIO ANTENNA

Connect: Satellite Radio Antenna Connection at the ACM.

Connect: Satellite Radio Antenna Cable In-Line Connection at the RH Scuff Plate Trim Panel.

Install a new satellite radio antenna. Refer to Antenna .

Drive the vehicle to an open location, free of obstacles.

Operate the audio system in satellite radio mode.

Does the system operate correctly?

Yes	The concern was caused by an inoperative satellite radio antenna. The system is operating correctly at this time.
No	GO to B5.

B5 CHECK FOR CORRECT ACM OPERATION

Ignition OFF.

Disconnect and inspect all ACM connectors.

Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or pins)
- Pushed-out pins (install new pins as necessary)

Reconnect the ACM connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new ACM. Refer to Audio Control Module (ACM) .
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
