What Does B1382 Mean?
This code indicates the Body Control Module (BCM) has detected a short to battery voltage in the oil change reset button circuit. The circuit is receiving constant battery voltage (typically 12V+) when it should be ground or open, indicating the button input line is shorted to a power source. This prevents the BCM from properly reading the oil change reset button state and may cause unintended oil life monitor behavior.
Common Causes
45%
Damaged or frayed wiring harness causing the reset button signal wire to contact a power wire or connector pin
30%
Faulty oil change reset button switch with internal short circuit to power
15%
Water intrusion or corrosion in the instrument cluster connector causing cross-circuit contamination
10%
Failed Body Control Module with internal circuit fault creating false short-to-battery condition
Diagnostic Steps
1
Step 1: Perform visual inspection of the oil change reset button and surrounding instrument cluster area for obvious damage, melted connectors, or signs of water intrusion. Check for aftermarket accessories or modifications that may have caused wiring damage.
2
Step 2: Disconnect the oil change reset button connector or instrument cluster connector (depending on vehicle architecture). Use a digital multimeter to measure voltage on the reset button signal wire at the harness side with ignition ON - should read 0V or 5V reference, not battery voltage (12V+).
3
Step 3: With connector still disconnected, measure resistance between the reset button signal wire and battery positive terminal. Reading should be infinite (open circuit). If continuity exists, trace the harness for pinch points, damaged insulation, or connector pin-to-pin shorts.
4
Step 4: If wiring tests normal, reconnect harness and back-probe the reset button signal wire while operating the button. Voltage should toggle between reference voltage and ground, never to battery voltage. If battery voltage appears, replace the reset button switch.

Step 5: Clear codes and verify repair by cycling ignition, operating reset button through normal function, and confirming no code recurrence. Monitor live data for proper reset button state changes during operation.

The most common cause of B1382 (Oil Change Reset Button Circuit Short To Battery) is: Damaged or frayed wiring harness causing the reset button signal wire to contact a power wire or connector pin
Typical repair costs for B1382 range from $75 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects the oil life monitoring reset function. The issue does not impact vehicle operation, braking, or safety systems, though it may prevent proper maintenance tracking and cause nuisance warning lights.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1382 to identify the root cause.
