B1461: Washer Pump Relay Short to Ground
The B1461 code indicates a short to ground in the winding of the windshield washer pump relay. This code is specific to Korean manufacturers, primarily Hyundai and Kia. The control module detects abnormally low resistance in the relay control circuit, preventing proper relay activation. The washer pump relay supplies power to the pump motor that sprays washer fluid onto the windshield.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty washer pump relay with internal short circuit in the coil
- Damaged wiring insulation in the relay control circuit causing contact with chassis ground
- Corroded or bent pins in the relay connector or shunt causing a short to ground
- Body Control Module (BCM) or wiper control module with internal damage to the relay control circuit
- Incorrect electrical modifications or installation of non-OEM accessories
3. Symptoms You Will Notice
- Washer pump does not operate or operates intermittently
- No washer fluid spray onto the windshield
- Blown fuse for the washer pump circuit
4. Step-by-Step Diagnosis
Check for blown fuses in the washer pump circuit and replace if necessary.
Inspect the washer pump relay for signs of damage or corrosion; test relay coil resistance and compare to specifications.
Visually inspect the wiring and connector for the relay control circuit for shorts, damage, or corrosion.
Measure resistance between the relay control circuit and ground; a low reading indicates a short.
If wiring and relay are okay, test the BCM or wiper control module output to the relay.
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive, but you will not have windshield washer function, which can be a safety hazard in poor visibility conditions. The issue is medium severity.
How much does it cost to fix?▼
Repair costs typically range from $100 to $300, depending on whether the relay, wiring, or module needs replacement. Diagnostic fees may add $50-$100.
