100%
Causes
- Damaged or corroded connector or wiring to Fuel Pump Control Module A (open, short, high resistance)
- Faulty or intermittent ground or supply voltage to the fuel pump control module
- CAN bus wiring fault (short to power/ground, open, high resistance, failed termination)
- Electromagnetic interference (noise) on the communication bus
- Software mismatch, corrupted calibration, or firmware bug in the fuel pump control module or other network module
- Fuel Pump Control Module A internal hardware or firmware failure
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Stored U0410 and possibly related network DTCs (U0100, U0401, etc.)
- No or intermittent fuel pump operation, hard start or no-start conditions
- Poor engine performance, stalling, or fuel pressure faults
- Inability for scan tool to communicate with Fuel Pump Control Module A or inconsistent data
What to check
- Read and record all DTCs, freeze frame and availability of live data from fuel pump control module and ECM/PCM
- Check for related network codes (U0100, U0401, U0073, etc.) and powertrain codes affecting fuel delivery
- Attempt to communicate with the fuel pump control module using a diagnostic scan tool
- Visually inspect connectors, seals and wiring for corrosion, damage, or moisture
- Check module supply voltage (key ON) and ground continuity
- Measure CAN_H and CAN_L behavior and check for proper termination (approx. one 120 ohm pair total)
Signal parameters
- CAN message ID(s) assigned to Fuel Pump Control Module A (vehicle-specific)
- Message frequency / refresh rate for fuel pump status frames (Hz)
- Payload fields commonly include: pump status (on/off), pump duty (%) or commanded current, supply voltage, fault/status flags
- Expected data ranges (pump duty 0–100%, supply voltage within battery/charging range)
- Checksum/CRC validity or sequence number consistency on CAN frames
- Presence and frequency of heartbeat/liveness frames
Diagnostic algorithm
- Use a scan tool to record U0410 plus all additional stored/active codes and freeze frame data; note operating conditions when fault set.
- Confirm whether the scan tool can communicate with the Fuel Pump Control Module A. If no communication, treat as lost comms vs invalid data.
- Visually inspect module connector and wiring for corrosion, bent pins, water intrusion, or damage; repair any obvious issues.
- Verify module supply and ground: measure battery voltage at the module connector (key ON) and check ground resistance to chassis/battery negative.
- Inspect CAN bus: check continuity and resistance between CAN_H and CAN_L, verify termination resistances, and look for shorts to power/ground.
- Use a CAN bus analyzer or oscilloscope to capture frames while the vehicle is running (or cranking). Check for correct message IDs, payload lengths, CRC/checksum errors and timing anomalies.
- Perform a wiggle test on harness and connectors while monitoring the bus for transient invalid frames or code set events.
- If wiring and bus are good, check module software/calibration levels against manufacturer bulletins; reflash/update if an update is available and recommended.
- If the module continues to transmit invalid data after wiring, power/ground and software verification, consider replacing the Fuel Pump Control Module A and re-test.
- After repairs, clear codes, re-run communication and function tests, and perform road test or lifecycle checks to confirm issue resolution and that code does not return.
Likely causes
- Corroded/loose connector pins at the fuel pump control module
- CAN bus wiring short or missing termination resistor
- Faulty ground or supply to the fuel pump control module
- Internal module failure or corrupted firmware
- Other control module on the CAN network transmitting corrupt frames
Fault status
Status
Invalid data received from Fuel Pump Control Module A — CAN message corrupted, out-of-range, or not received; requires inspection of wiring, power/ground, CAN bus, and module.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3.0 hours
