B1385
Low Severity (Level 2)Oil Level Lamp Circuit Open
B1385 usually means oil Level Lamp Circuit Open.
Can you still drive with B1385?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $60 – $700
Severity Level 2 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Body electronics not working — no response when activated
- Body electronics working intermittently, then stopping completely
- Infinite resistance in the body electrical circuit — broken wire or disconnected connector
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the body electrical system
Possible Causes
- Broken wire or connector pin in the body electrical system harness — common at flex points like door jambs or where wiring moves
- Disconnected or loose electrical connector — may have been bumped during other repairs
- Failed body control module (BCM) or sensor — internal open circuit from age, heat cycling, or vibration
- Corrosion completely severing a wire or connector terminal — green crust on copper wiring
- Wiring harness damage from rodent chewing — look for nesting material near the engine or under dash
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($11-127 at shop, free at auto parts store for basic scan)
- Visually inspect the body electrical system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $88 diagnostic fee at shop)
- Trace the body electrical system wiring from connector to connector with a multimeter set to continuity/resistance mode — find and repair the break in the circuit ($133-400 labor for diagnosis and repair)
- Check and reseat all connectors in the body electrical system circuit — disconnect, inspect pins, clean with electrical contact cleaner, apply dielectric grease, and reconnect firmly ($10 DIY or $59 shop minimum)
- If body control module (BCM) or sensor has failed internally (open circuit inside), replace it — don't try to repair sealed components ($50-600)
