100%
Causes
- Faulty or disconnected GPS antenna (physical damage, corrosion, water intrusion)
- Broken or shorted antenna coaxial cable or connector
- Poor ground or power supply to GPS/navigation module
- Intermittent or lost CAN/LIN/serial communication between GPS module and infotainment/telematics module
- Failed GPS/navigation module (internal electronics or firmware)
- External RF interference or strong local jamming
Symptoms
- “No GPS signal” or “Searching for satellites” messages on infotainment screen
- Navigation position inaccurate or not updating
- Telematics services (onStar/connected services) unavailable or degraded
- Vehicle features that rely on GPS (speed-based features, time sync) not functioning correctly
- B2462 stored in PCM/BCM/navigation module and possibly related communication codes
What to check
- Scan vehicle and record B2462 plus any related DTCs and freeze frame data
- Check technical service bulletins (TSBs)/software updates for GPS/navigation module
- Visually inspect GPS antenna, mounting, and coax connectors for damage, corrosion, or water intrusion
- Verify continuity and shielding of antenna coax back to module (use an ohmmeter/insulation check)
- Check power and ground at the GPS/navigation module connector (compare to vehicle reference values)
- Use a scan tool to monitor GPS module parameters: satellite count, fix type, signal strength, NMEA/position output and message frequency
Signal parameters
- Satellites in view: typically >=4 required for reliable 3D fix (manufacturer-specific)
- Fix type: 3D fix preferred (no fix or 2D indicates poor signal)
- Signal strength: carrier power typically >25–35 dB-Hz per satellite (varies by receiver)
- HDOP (horizontal dilution of precision): lower is better; typical acceptable HDOP
- Position update rate: commonly 1 Hz (check module spec)
- Module power: vehicle battery/ignition supply present at module connector (check 12 V feed and module regulator outputs per service manual)
Diagnostic algorithm
- Connect a capable scan tool and read all stored DTCs and freeze frame data; note time-stamped events and related codes.
- Check for any TSBs or software updates for the infotainment/navigation/GPS module and apply if applicable.
- Visually inspect GPS antenna, mount, and cable routing for physical damage, water intrusion, corrosion, or loose connectors.
- With key on (engine off as required), verify power and ground at the GPS/navigation module connector. Record voltages and compare to spec.
- Inspect and test the antenna coax: check connector seating, measure continuity and shield continuity to module; check for short to chassis. Replace coax/connector if damaged.
- Use scan tool live data to monitor GPS parameters: satellites in view, fix type, signal strength, update rate. If no or zero satellites, suspect antenna/cable/power or severe interference.
- Perform a controlled open-sky road test or place vehicle where sky view is clear to rule out blocking or local RF interference.
- If wiring and antenna check good but receiver shows no fix or erratic data, try performing a module reset/reboot and clear codes. Re-test.
- If issue persists, swap/replace GPS antenna with known-good unit and re-check. If still failing, consider replacing or reprogramming the GPS/navigation module per manufacturer procedures.
- After repairs, clear codes and verify system operation over an appropriate run time (road test) and confirm no recurrence of B2462.
Likely causes
- Damaged/disconnected GPS antenna or coax (most common)
- Power/ground fault to GPS/navigation module
- Faulty GPS/navigation module or firmware
- Communication bus fault between modules
Fault status
Status
GPS Signal Error (B2462) — navigation/telematics module detected loss or degraded quality of GPS signal. Fault logged; check antenna, cabling, power/ground, and module communications.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
