Turn the ignition off.
Disconnect the Satellite Receiver Antenna connector.
Disconnect the Satellite Radio Receiver harness connectors.
Measure the resistance between ground and the Satellite Signal circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the Satellite Signal circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 5
5
Turn the ignition off.
Check the antenna for physical damage.
Disconnect the Satellite Receiver Antenna connector.
Disconnect the Satellite Radio Receiver harness connectors.
NOTE: Check the related wiring terminals for corrosion, damage or termi-
nal push out. Repair as necessary.

Symptom List:
BUS BUSY - SDARS
PCI BUS SHORTED TO BATTERY - MHSAPM
PCI BUS SHORTED TO GROUND - MHSAPM
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be BUS BUSY - SDARS.
When Monitored and Set Condition:
BUS BUSY - SDARS
When Monitored:
With the ignition in run, and the IOD fuse installed.
Set Condition:
Anytime the module detects a short to battery on the PCI Bus circuit.
PCI BUS SHORTED TO BATTERY - MHSAPM
When Monitored:
Continuously.
Set Condition:
Anytime the module detects a short to battery on the PCI Bus circuit. DTC
will mature immediately.
PCI BUS SHORTED TO GROUND - MHSAPM
When Monitored:
Continuously.
Set Condition:
Anytime the module detects a short to ground on the PCI Bus circuit. DTC
will mature immediately.
POSSIBLE CAUSES

NOTE: For this code to be active, the DRB will not be able to communicate
with any modules on the vehicle (except the PCM).
NOTE: Clear the code. If this code continues to set and the DRB can still
communicate with the module, it will be necessary to replace the module.
NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, wiggle the wiring
harnesses. This is to try and duplicate the complete bus failure condition.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?
All
Yes
→ Repair as necessary.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Test Complete.
