Pinpoint Test N: The SIRIUS(R) Data Services Are Not Available In Navigation Mode
Normal Operation
SIRIUS(R) data services (live traffic, movies, weather, gas prices, sports score tracking) is sent from the Audio Control Module (ACM) internal satellite radio receiver to the Accessory Protocol Interface Module (APIM). In navigation mode, the traffic/weather is displayed and is used to anticipate traffic delays and find alternate routes to the destination.
This pinpoint test is intended to diagnose the following:
- Satellite audio system concern
- Wiring, terminals or connectors
- ACM (Audio Control Module)
- APIM (Accessory Protocol Interface Module)
PINPOINT TEST N : THE SIRIUS(R) DATA SERVICES ARE NOT AVAILABLE IN NAVIGATION MODE
N1 CHECK FOR SATELLITE AUDIO CONCERNS
- Ignition ON.
- Carry out the ACM (Audio Control Module) self-test.
- Operate the infotainment system in satellite audio mode.
Are any satellite audio concerns present?
Yes
REFER to DTC Charts Accessories and Optional Equipment or GO to Symptom Chart - Satellite Radio Symptom Chart - Satellite Radio.
No
GO to N2.
N2 VERIFY AN ACTIVE SUBSCRIPTION
- Operate the audio system in SIRIUS(R) data services mode and observe the infotainment display.
Does the display indicate the subscription has expired?
Yes
The subscription has expired. INFORM the customer to contact Sirius to reactivate the subscription.
No
GO to N3.
N3 CHECK THE SATELLITE DATA CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: Audio Control Module (ACM) C240B.
- Disconnect: Accessory Protocol Interface Module (APIM) C2383.
- Ignition ON.
- Measure the voltage between the ACM (Audio Control Module) C240B-6, circuit VME90 (GY/BU), harness side and ground; and between the ACM (Audio Control Module) C240B-19, circuit VME91 (WH/BN), harness side and ground.
Is any voltage present?
Yes
REPAIR the circuit for a short to voltage. TEST the system for normal operation.
No
GO to N4.
N4 CHECK THE SATELLITE DATA CIRCUITS FOR AN OPEN OR SHORT TO GROUND
- Ignition OFF.
- Measure the resistance between the ACM (Audio Control Module), harness side and APIM (Accessory Protocol Interface Module), harness side; and between the ACM (Audio Control Module), harness side and ground as follows:
Positive Meter Lead Negative Meter Lead Circuit C240B-6 C2383-51, then ground VME90 (GY/BU) C240B-19 C2383-52, then ground VME91 (WH/BN)
Is the resistance less than 5 ohms between the ACM (Audio Control Module) and the APIM (Accessory Protocol Interface Module) and greater than 10,000 ohms between the ACM (Audio Control Module) and ground?
Yes
GO to N5.
No
REPAIR the circuit. TEST the system for normal operation.
N5 CHECK FOR CORRECT ACM (Audio Control Module) OPERATION
- Disconnect all the ACM (Audio Control Module) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the ACM (Audio Control Module) connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new ACM (Audio Control Module). REFER to Audio Control Module (ACM) . TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR any DTCs present.
