What Does B2114 Mean?
B2114 indicates the Body Control Module (BCM) has detected a short circuit to ground in the front windshield washer pump input circuit. This means the electrical signal wire that commands the washer pump to operate is making unintended contact with chassis ground, causing excessive current flow or preventing proper operation. The BCM monitors this circuit and sets this code when voltage drops below expected parameters, typically when the washer switch is activated or during continuous monitoring.
Common Causes
45%
Damaged or chafed wiring harness between BCM and washer pump with insulation worn through, causing direct ground contact
30%
Failed windshield washer pump with internal short circuit to ground through motor windings or housing
15%
Corroded or moisture-damaged washer pump connector causing short to ground path
10%
Faulty washer control switch with internal short creating ground path when activated
Diagnostic Steps
1
Step 1: Perform visual inspection of washer pump wiring harness from BCM to pump, checking for pinched, chafed, or damaged wires especially near sharp metal edges, hood hinges, and frame rails. Look for exposed copper wire or melted insulation.
2
Step 2: Disconnect the washer pump electrical connector and clear the code. Attempt to recreate the fault by activating the washer switch. If code returns immediately, the short is in the wiring harness between BCM and pump connector; if code does not return, problem is in the pump itself.
3
Step 3: Using a digital multimeter set to resistance mode, measure continuity between the washer pump control wire (at the disconnected harness side) and chassis ground with washer switch off. Reading should be infinite resistance (open circuit); any continuity indicates a short to ground in the harness.
4
Step 4: If harness tests good, measure resistance across the washer pump motor terminals. Compare to specifications (typically 2-5 ohms). Then measure resistance from each pump terminal to pump housing/ground. Should read infinite resistance; any continuity indicates internal pump short.
5
Step 5: Inspect washer pump connector terminals for corrosion, pushed-back pins, or moisture intrusion. Check connector housing for cracks allowing water entry. Clean terminals with electrical contact cleaner and dielectric grease if corrosion present.

Step 6: After repair, reconnect all components, clear codes, and cycle washer pump multiple times while monitoring live data for proper voltage and current draw. Verify no codes return and pump operates normally.

The most common cause of B2114 (Front Washer Input Short to Ground) is: Damaged or chafed wiring harness between BCM and washer pump with insulation worn through, causing direct ground contact
Typical repair costs for B2114 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 windshield washer function, not critical vehicle operation. However, reduced visibility from inability to clean windshield could become a safety concern in poor weather conditions, so repair within a reasonable timeframe is recommended.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2114 to identify the root cause.
