P0D27: Battery Charger Input Voltage Too Low

P0D27 says the AC voltage reaching the on-board charger sits lower than the charger accepts while charging is permitted. Unlike most charger codes, the cause often lies outside the car. Mitsubishi's Outlander PHEV stops charging and tells technicians to check, in order, the customer's power supply, the charging cable, the high-voltage wiring between charge inlet and charger and finally the charger itself. Stellantis lists P0D27-00 as Battery Charger 1 Input Voltage Too Low in the integrated dual charging module of the 2021 Jeep Wrangler 4xe, with MIL, no level 2 charging and in some cases a tripping house breaker; the remedy is new IDCM software along with several other modules. Later notes ask for a test charge after clearing before an IDCM is replaced. Too high an input voltage is P0D28.

Symptoms

• AC charging does not start or stops
• House circuit breaker trips when plugging in
• MIL

Most likely causes

• Weak or overloaded AC supply at the charging location
• Faulty charging cable or EVSE
• Charger module software (Stellantis IDCM reflash)
• Damaged wiring or loose contact between charge inlet and charger

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. With the connector unplugged, check whether the signal wire is making contact with ground.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• Repair difficulty: medium

What each character of P0D27 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• D: Subsystem depends on the code range
• 27: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0D27?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0D27?

The most common causes are: weak or overloaded AC supply at the charging location; faulty charging cable or EVSE; charger module software (Stellantis IDCM reflash).
