B1382 — Oil Change Reset Button Circuit Short Battery

Manufacturer-specificBody

B1382 means the oil change reset button/switch circuit is reading a continuous battery-voltage signal when it should not, indicating a short to power somewhere in that circuit. The fault is usually in the button, its wiring, or a connector, rather than the engine or powertrain. It will typically prevent the oil-change reminder from being reset with the dashboard button.

Symptoms

Oil change reminder light/message cannot be reset with the reset button
Reset button feels stuck, unresponsive, or operates intermittently
No physical drivability or engine performance problems
Dashboard warning or service indicator may stay on
Other dashboard buttons or functions continue to work normally

What causes it — most likely first

1. Failed or internally shorted oil change reset button/switch

The button itself can wear out, corrode, or develop an internal short that keeps the circuit pulled to battery voltage. This is the single most common cause for this specific code.

2. Wiring short to battery voltage

The harness between the reset button and the receiving module can chafe, pinch, or melt against a power feed, causing the signal wire to be constantly powered.

3. Connector or terminal damage/corrosion

Loose, bent, or moisture-corroded terminals at the button or module connector can allow the signal pin to touch a power source or remain at battery voltage.

4. Aftermarket device tapped into the circuit

An add-on accessory wired into the reset-button circuit can back-feed voltage or alter the expected signal, triggering a short-to-battery fault.

5. Fault in the receiving control module input

The instrument cluster, body control module, or other receiving module could have a rare internal input failure that misreads the circuit as shorted to battery voltage.

How it's diagnosed

Inspect the reset button, connector, and visible wiring for damage, corrosion, pinched insulation, or signs of liquid intrusion.
Disconnect the reset button and measure the signal circuit; if battery voltage is still present, the short is in the harness or module, not the button.
Check the button itself with an ohmmeter to confirm it opens and closes properly and is not internally shorted to power.
Trace the wiring between the button and the receiving module, looking for chafing against metal frames, harness ties, or other power circuits.
If the button and harness test normal and no external back-feed exists, evaluate the receiving module input before considering module replacement.

Frequently asked

Can I still drive with code B1382?

Yes. This code only affects the oil change reset button circuit and has no effect on engine operation, emissions, or safety systems. The main inconvenience is that the service reminder cannot be cleared with the button.

Will I need to replace the PCM or engine computer for B1382?

Almost certainly not. This is a body/instrument panel circuit code, and the fix is usually the reset button, its connector, or the wiring. PCM replacement is not a realistic cause for this fault.

Can the oil change reminder be reset another way while this is being repaired?

Some vehicles allow reset through the driver information menu, steering-wheel controls, or a scan tool, but procedures vary by make and model. The repair should restore normal button function.

Why does the code say 'Short Battery' instead of 'Short Ground'?

'Short Battery' means the circuit is shorted to a power source and is staying at battery voltage when it should be at a lower or changing voltage. A short to ground would pull the circuit near zero volts and usually set a different fault description.
