Digital Radio Antenna Circuit Malfunction
- Ignition OFF, disconnect the digital radio antenna coax from the digital radio receiver (DRR). Connect the EL-48028 antenna to the DRR and move the vehicle outside in an area with an unobstructed view of the southern sky, tune to XM.
- Ignition ON, radio tuned to XM, verify XM reception is clear and uninterrupted.
- If reception is not clear, replace the DRR.
- Ignition OFF, reconnect the antenna coax to the DRR, disconnect the digital radio antenna coax from the digital radio antenna.
- Ignition ON, test for 4.5-5.5 V between the antenna coax center terminal and the coax outer shield.
- If not within the specified range, replace the antenna coax.
- If all circuits test normal, replace the digital radio antenna.
Digital Radio Output Circuit Malfunction
- Ignition OFF, disconnect the X2 harness connector at the radio.
- Ignition ON, radio ON and tuned to XM, test for a varying mV AC voltage reading between the following signal circuit terminals listed below and ground.
- Left audio signal (+) - terminal 1
- Right audio signal (+) - terminal 2
- Audio common signal (-) - terminal 9
- If the varying mV A/C voltage reading is not present, test the signal circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the DRR.
- If all circuits test normal, replace the radio.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
