B1382 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• module resets or glitches
• feature inoperative intermittently
• battery draw complaints

Common causes

• Disconnected or loose connector affecting oil change reset button circuit short to battery
• Open circuit in wiring
• Connector pin damage/corrosion or harness stress near related components

How to diagnose B1382

1. Confirm B1382 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to oil change reset button circuit short to battery for obvious defects.
3. Use a continuity test from module pin to component to identify opens/high resistance.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code B1382

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with B1382?

Most vehicles can be driven short-term with B1382, but postpone heavy load/highway driving until repaired.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (open) in the oil change reset button circuit short to battery circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify B1382 remains cleared under the conditions that originally set the code.

Fix options

• Repair open circuit and secure connector lock.
• Clear corrosion and protect terminals.
• Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$160-$850

Common mistakes when diagnosing B1382

• Replacing parts without verifying voltage, ground, and signal integrity first.
• Ignoring related stored/pending codes that indicate upstream faults.
• Skipping post-repair verification drive cycle and readiness checks.

B1382 in common vehicles

B1382 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.
