Oil change reset button short to positive

Causes
- Damaged insulation or pinched wiring causing the switch circuit to contact battery positive
- Corroded, bent or contaminated switch connector pins
- Failed/reset switch with internal short
- Aftermarket accessories or recent repairs with incorrect connections
- Water ingress or corrosion at the switch or connector
- Instrument cluster / BCM internal input damage or fault
Symptoms
- Oil/service reminder will not reset after performing service
- Service reminder lamp or message remains illuminated
- Intermittent or permanent DTC B1382 stored in body control module or cluster
- Possible erratic cluster behavior on related inputs
- Battery drain (rare) if short is persistent
What to check
- Scan vehicle and read stored/active DTCs and freeze-frame data; note any related codes
- Visually inspect the oil-change reset button, bezel and wiring harness for damage, corrosion or water ingress
- Check connectors for bent pins, contamination, or loose terminals
- Inspect nearby wiring for chafing where it passes through bulkheads or around engine bay components
- Check fuses and grounds related to instrument cluster/BCM
- If aftermarket devices were installed recently, inspect/remount or disconnect them
Signal parameters
- Key ON (engine off): measure voltage at switch connector — expected: battery voltage (~12V) on the supply side
- Switch output terminal at rest (open): expected ~battery voltage via pull-up; when pressed (closed) expected low (near 0 V) if circuit is pulled to ground, or change per manufacturer wiring (verify schematic)
- Resistance across switch terminals: open >10 kΩ; closed near 0–5 Ω (exact spec varies by vehicle)
- Check for unintended battery positive on the switch signal wire with switch removed — presence of +12V when it should be low indicates short to positive
- Continuity from signal wire to BCM/cluster input should be present; check for shorts to power or other circuits
Diagnostic algorithm
- Connect a diagnostic tool; record the code and clear codes to see if B1382 reappears.
- Visually inspect the reset button assembly and harness; look for damaged insulation, melted connectors, or corrosion.
- Remove the switch connector. With ignition ON, back-probe the connector pins and verify supply and signal voltages against expected values.
- Operate the switch while monitoring the signal wire: verify the voltage transitions (open vs pressed). If the signal does not change correctly or shows permanent +12V, suspect a short to positive.
- Disconnect the switch and measure resistance from the signal wire to battery positive and to chassis ground. A short to +12V will show continuity to battery positive.
- Perform a wiggle test along the harness while monitoring the signal for intermittent shorts. Pay attention where harnesses pass through bulkheads or near moving parts.
- If wiring/connector checks are good, back-probe the module input at the BCM/cluster connector to confirm the signal behavior at the module side. If the short is present at the module connector, inspect cluster/BCM grounds and consider module internal fault.
- Repair or replace damaged wiring, terminals or the switch. Clean or replace corroded connectors. Remove aftermarket additions or re-route/insulate harnesses as required.
- After repair, clear codes, perform the prescribed oil-change reset procedure, and verify that the code does not return during a functional check or short road test.
Likely causes
- Shorted wiring at or near the oil-change reset button (most likely)
- Faulty/reset switch assembly
- Connector corrosion or foreign material bridging terminals
- Incorrectly installed aftermarket device tapping into same circuit
- Rare: internal module input fault
Fault status
Status
Active fault stored when the oil-change reset button signal is detected shorted to battery positive. May be intermittent; will prevent successful service indicator reset until resolved.
Repair difficulty: Medium
Diagnostic time: 0.5-1.5 hours
