B2328-WASHER FLUID LEVEL SENSOR INPUT CIRCUIT HIGHB2328-Washer Fluid Level Sensor Input Circuit High:
WHEN MONITORED
With the ignition on.
SET CONDITION
When the FCM detects a High condition.
POSSIBLE CAUSES
- Washer fluid level sensor
- (Z901) ground circuit
- (W1) washer fluid level switch sense
- Front control module
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.
DIAGNOSTIC TEST
1. INTERMITTENT CONDITION
Turn the ignition on.
With the Scan Tool, clear all FCM DTC's.
Turn the Wiper Washers on.
With the Scan Tool, read the Wiper DTC's.
Q: Does the Scan Tool read: B2328-WASHER FLUID LEVEL SENSOR INPUT CIRCUIT HIGH?
YES: Go To 2
NO: The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
2. WASHER FLUID LEVEL SENSOR
Turn the ignition off.
Disconnect the Wiper Washer Fluid Level Sensor connector.
Measure the internal resistance of the Washer Fluid Level Sensor between cavity 1 and 2 of the sensor.
Q: Is the resistance above 5.0 ohms?
YES: Replace the Washer Fluid Level Sensor. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 3
3. Z901 WASHER FLUID LEVEL SENSOR GROUND CIRCUIT
Turn the ignition off.
Disconnect the Washer Fluid Level Sensor connector.
Measure the resistance between ground and the (Z901) ground circuit.
Q: Is the resistance above 5.0 ohms?
YES: Repair the (Z901) Ground circuit for a short condition. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 4
4. W1 WASHER FLUID LEVEL SENSOR CONTROL CIRCUIT
Turn the ignition off.
Disconnect the Washer Fluid Level Sensor connector.
Disconnect the Front Control Module C1 connector.
Measure the resistance of the (W1) Washer Fluid Level Sensor control circuit.
Q: Is the resistance above 5.0 ohms?
YES: Repair the (W1) Washer Fluid Level Sensor control circuit. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the Front Control Module. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
