Damaged, chafed or corroded wiring or connector on the pedestrian alert module circuit, causing a short to ground or high resistance; Low or missing supply voltage or poor earth to the pedestrian alert module; Low 12-volt battery voltage or a charging system fault affecting module supply; Blown fuse or faulty relay feeding the pedestrian alert circuit; Faulty pedestrian alert control module or its speaker or sounder, pulling the circuit low; Internal fault in the controlling unit or outdated software, where the manufacturer has identified this as a known cause.

P: SystemPowertrain
0: Defined bySAE, the same on every car
D: AreaReserved
EE: FaultThe specific fault in that area

What it means

P0DEE means the powertrain control system has detected a low voltage or signal on the circuit linked to the pedestrian alert control module, which drives the low-speed warning sound on hybrid and electric vehicles. The monitoring control unit saw a circuit voltage below the expected range, which points to a short to ground, high resistance, or a power supply fault. The exact circuit, module location and wiring layout depend on the model.

Symptoms

Warning light on, such as the main fault or hybrid/EV system lamp, depending on model
Pedestrian warning sound missing, quieter than normal or intermittent at low speed
Other warning sound or speaker faults stored alongside the code
No noticeable change in driving performance
Fault returns soon after clearing

Possible causes

Damaged, chafed or corroded wiring or connector on the pedestrian alert module circuit, causing a short to ground or high resistancelikely
Low or missing supply voltage or poor earth to the pedestrian alert modulelikely
Low 12-volt battery voltage or a charging system fault affecting module supplypossible
Blown fuse or faulty relay feeding the pedestrian alert circuitpossible
Faulty pedestrian alert control module or its speaker or sounder, pulling the circuit lowpossible
Internal fault in the controlling unit or outdated software, where the manufacturer has identified this as a known causerare

How to diagnose

Read all stored and pending codes and freeze frame data, noting battery voltage and conditions when the fault set, and look for related battery, speaker or communication codes
Check the 12-volt battery condition and charging voltage, as low supply voltage can set circuit low faults
Inspect the pedestrian alert module, its speaker and the related wiring and connectors for damage, water ingress, corrosion or loose pins, using the model wiring diagram
Check the relevant fuses and relays for continuity and correct supply
Measure supply voltage and earth integrity at the module connector with the ignition on, against the manufacturer specification
Test the circuit for short to ground and excessive resistance with the connector disconnected and the system safely isolated, following the manufacturer procedure
Check the speaker or sounder and module operation using an output test if the scan equipment supports it
Check for manufacturer service information or software updates relating to this code for the specific model

How to fix

Repair or replace damaged wiring, terminals or connectors, and seal against moisture
Restore the correct supply or earth connection to the module
Replace a blown fuse or faulty relay after finding why it failed
Charge or replace a weak 12-volt battery and repair any charging fault
Replace the faulty pedestrian alert module or speaker, with any required programming
Apply a manufacturer software update only if an outdated calibration is the confirmed cause

Can I keep driving?

Low severity

The car can normally be driven as it should not affect drivability, but the pedestrian warning sound may not work. Book it in soon, as this system is a safety and legal requirement on many hybrids and electric vehicles.
