U016A – Lost Communication With Global Positioning System Module: Symptoms, Causes, Diagnosis & Repair Cost (2026 Guide)

U016A

Last updated:

Overview

The control module stored U016A because it detected a problem with: Lost Communication With Global Positioning System Module.

U016A relates to Lost Communication With Global Positioning System Module. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.

What does the U016A code mean?

When U016A is set, the vehicle’s diagnostics detected an issue described as: Lost Communication With Global Positioning System Module. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.

Common symptoms of U016A

  • Intermittent features
  • Random U-code clusters
  • Aftermarket install issues
  • Module not communicating
  • Multiple warning lamps
  • No-start or limp mode

Possible causes

  • Fault affecting Lost Communication With Global Positioning System Module (wiring, connector, or component)
  • Module power/ground instability
  • CAN wiring or termination issues
  • Gateway or routing problems
  • Control module or software calibration issue (less common—verify tests first)
  • Past repairs or aftermarket parts causing out-of-spec operation

How to diagnose U016A

  1. Scan for U016A and review freeze frame / pending codes for related faults
  2. Inspect connectors and wiring related to: Lost Communication With Global Positioning System Module
  3. Compare live data and commanded vs actual values for the affected system (per service information)
  4. Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
  5. Confirm power and ground integrity at the relevant module or sensor
  6. After repair, clear DTCs and verify under the conditions that originally set U016A

Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.

Severity of code U016A

Moderate: Communication faults can disable features or store multiple warnings until the network or module issue is fixed.

Can you drive with U016A?

Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.

Avoid heavy acceleration, towing, or long highway drives until the cause of U016A is confirmed and repaired.

How to fix it (step-by-step)

  1. Start with visual inspection and connector cleaning/tightening where needed
  2. Confirm failure mode with testing—avoid swapping parts without evidence
  3. Repair wiring or replace the failed component per manufacturer procedure
  4. Clear faults, run relearns if required, and road test to confirm

Repair & fix options

  • Verify termination where applicable
  • Repair network wiring and grounds
  • Diagnose offline module power first
  • Clear codes and verify repair with a drive cycle and readiness where applicable
  • Reinspect related monitors if the code returns after repair

Typical repair cost

$100 – $1,800+ depending on cause

Estimated cost breakdown for U016A
Repair type Typical range
Diagnostic And Minor $120 – $600
Common Component Work $100 – $500
Major Subsystem Repair $400 – $1,800+
Severe Or Replacement $150 – $900

How to help prevent U016A in the future

  • Fix new codes early before secondary damage or catalyst stress
  • Keep connectors clean and secure; address rodent or water intrusion in harnesses
  • Use the correct fluids/parts for your vehicle and service intervals
  • Avoid ignoring pending codes after battery work or repairs

When to see a mechanic

Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.

Common mistakes when diagnosing U016A

  • Replacing sensors/modules without verifying wiring and reference voltages
  • Ignoring related codes that identify the real root cause
  • Clearing codes without a verification drive cycle

Common vehicles & notes for U016A

  • Nissan / Hyundai models (common examples—verify for your vehicle)
  • Kia / Mazda applications vary by engine and model year
  • Many other makes—this is a standardized OBD-II definition: Lost Communication With Global Positioning System Module

U016A is reported across many platforms including Nissan, Hyundai, Kia, Mazda. Always use VIN-specific service information for testing limits and calibration steps.

Frequently asked questions

What does U016A mean?

U016A indicates a fault involving Lost Communication With Global Positioning System Module, based on what the control module detected during self-tests or live monitoring.

Is it safe to drive with U016A?

If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.

How much does it cost to fix U016A?

Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.

What is the most common cause of U016A?

Most shops start with wiring/connectors and the directly monitored component for “Lost Communication With Global Positioning System Module,” then expand testing if the fault returns.

Will U016A clear itself?

It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.

Can a weak battery cause U016A?

Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
