Wiper Hi/Low Speed Circuit Motor Short To Battery

What This Actually Means

In plain language — no jargon

The wiper motor circuit is shorted directly to battery power, causing the motor to receive too much voltage. It's like a light switch that's stuck in the ON position with full power constantly flowing through.

Symptoms You May Notice

3 known symptoms for this code
Wipers stay on continuously or operate at high speed only
Wipers do not respond to speed control settings
Burning smell or smoke from wiper motor area

How Your ECU Detects This

Technical sensor logic and voltage thresholds

The ECU monitors voltage and current draw on the wiper motor circuit. When the circuit shorts to battery voltage, the ECU detects abnormally high voltage (near 12-14V continuously) and excessive current draw that doesn't match commanded speed levels. The fault triggers when measured voltage exceeds normal operational thresholds.

Voltage & Parameter Thresholds

ParameterNormal RangeFault Condition
Motor circuit voltage 0-5V variable per speed command >10V sustained without command
Current draw 2-8A depending on speed >12A continuous draw

Diagnostic & DIY Fix Guide

Check these in order — from cheapest to most complex
1
Wiper motor relay
Inspect and replace the relay as it may be stuck closed, causing the short-to-battery condition.
2
Wiper motor connector/wiring
Check for damaged insulation, pinched wires, or corrosion at the motor connector that could cause contact with battery voltage.
3
Wiper motor assembly
Replace the motor if internal windings are shorted or internal switch contacts are fused closed.

When to See a Professional Mechanic

Not all fault codes are safe to DIY

Code B1467 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.

Safety note: OBD-II codes identify the system or circuit where a fault was detected — they do not always identify the exact failed component. A professional mechanic using live sensor data will diagnose the root cause more accurately than replacing parts based on the code alone.

How to Clear Code B1467

What happens after you fix the fault

Once the fault is repaired, B1467 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.

The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.

✅ Safe to Clear When
  • Fault has been diagnosed and repaired
  • You want to confirm the repair worked
  • Code appeared after a sensor was cleaned
⚠️ Do Not Clear When
  • Preparing for an emissions/PUC test
  • Root cause is still undiagnosed
  • Check engine light is flashing
Emissions test note: Clearing codes resets OBD readiness monitors. Most vehicles need 50–100 km of mixed driving before monitors complete. Do not clear codes immediately before an emissions or PUC inspection.
