Damaged, chafed or broken wiring in the module or speaker circuit; Corroded, loose or pushed-out pin in a connector at the module; Open circuit in the module's power supply or earth, such as a blown fuse or poor earth point; Faulty pedestrian alert module; Faulty or disconnected external alert speaker, if it is part of the monitored circuit; Outdated or faulty control unit software, where the manufacturer has identified it as a cause.

What it means

P0DED is the generic code for a fault in the circuit to the pedestrian alert control module, specifically an open circuit. The pedestrian alert system produces an artificial sound at low speed on quiet hybrid and electric vehicles. The powertrain or body control unit set the code because it detected no continuity, or no valid response, on the circuit to the module. Exact module location, wiring and test values vary by model.

Symptoms

Pedestrian alert warning sound missing or intermittent at low speed
Warning light or message in the instrument cluster, depending on the model
Fault code stored, with the check engine or system fault lamp on in some vehicles
Vehicle unusually quiet when moving slowly or reversing
Other related alert system or speaker fault codes stored

Possible causes

Damaged, chafed or broken wiring in the module or speaker circuitlikely
Corroded, loose or pushed-out pin in a connector at the modulelikely
Open circuit in the module's power supply or earth, such as a blown fuse or poor earth pointpossible
Faulty pedestrian alert modulepossible
Faulty or disconnected external alert speaker, if it is part of the monitored circuitpossible
Outdated or faulty control unit software, where the manufacturer has identified it as a causerare

How to diagnose

Read all stored codes and freeze frame data, noting whether the fault is current or intermittent and whether other codes are present
Check the battery condition and system voltage, as low voltage can cause spurious circuit faults
Inspect the visible wiring, connectors and earth points on the module and speaker for damage, water ingress, corrosion or previous repairs
Check the relevant fuses and relays against the wiring diagram for your model
Wiggle-test the harness and connectors with live data or the system active to see if the fault appears or clears
With the connector disconnected, test the module's supply, earth and signal circuits for continuity and voltage against the manufacturer's data
Test the speaker and its wiring as specified for the model, and confirm whether the system can be activated by a diagnostic function
Check for any manufacturer service information or software updates relating to this code on your model

How to fix

Repair or replace damaged wiring, using proper soldered or crimped and sealed repairs
Clean, repair or replace corroded or damaged connectors and terminals
Restore the power supply or earth, replacing any blown fuse only after finding why it failed
Replace a faulty alert speaker if testing shows it is open circuit
Replace the pedestrian alert module if the wiring and supplies are good, and code or programme it as the manufacturer requires
Apply a manufacturer software update if one is documented for this fault

Can I keep driving?

Low severity

The car is usually safe to drive, but it may be much quieter than normal at low speed, so take extra care around pedestrians. Book it in soon, as the alert system may be a legal requirement in some regions.
