P0231 on Chrysler by model: symptoms, diagnosis and fix
The TIPM main fuse and relay box circuit board traces blow from current spikes, shorts, or corrosion. Water intrusion common. Causes random electrical issues affecting fuel pump, lights, wipers, horn, windows, and safety systems.
Common Symptoms
- Vehicle won't start but has power
- Random activation of lights, wipers, or horn
- ABS/airbag warning lights
- Fuel pump running continuously
- Intermittent starting issues
How to Fix
TIPM replacement or professional rebuild. Specialty companies offer rebuild services for $200-400 with warranty. OEM replacement from dealer $700-1,200 plus programming. Disconnect battery for 10 minutes to attempt temporary reset.

The TIPM central fuse/relay box controls nearly all vehicle electrical functions. Internal relays, especially the fuel pump relay, fail due to solder joint cracking from thermal cycling. Causes random activation of lights, wipers, horn, sliding doors losing power, battery drain, and no-start conditions. Class-action lawsuit filed. Most severe in 2008 and 2010-2011 model years.
Common Symptoms
- Vehicle won't start (fuel pump relay failure)
- Fuel pump runs continuously with key off
- Wipers, horn, or lights activate randomly
- Power sliding doors lose power mid-operation
- Battery drain from interior lights activating overnight
- ABS/airbag warning lights
How to Fix
Three options: (1) New TIPM from dealer ($800-$1,500 + programming), (2) Mail-in TIPM rebuild service from UpFix, Circuit Board Medics, or MAKS TIPM ($200-$400, plug-and-play, no programming needed), (3) External fuel pump relay bypass cable ($50-$150) for fuel pump relay issue only.

The Totally Integrated Power Module (TIPM), located in the engine compartment near the air cleaner assembly, houses all important fuses and power relays. Water intrusion into the module can cause corrosion and electrical system failures. The TIPM controls critical systems including fuel pump operation, headlights, airbags, door locks, and air conditioning.
Common Symptoms
- Fuel pump not activating (engine cranks but won't start)
- Headlights not working or flickering
- Random electrical failures
- Airbag warning light
- Door locks malfunctioning
- Air conditioning not working
- Dead battery
How to Fix
TIPM repair services can rebuild the unit for $200-$400, which is more cost-effective than purchasing a new OEM TIPM ($600-$1,200 for parts plus $100-$200 labor for programming and installation). Address any water intrusion issues by checking seals and drainage.

The Aspen shares the TIPM electrical module design with other Chrysler products. Fuel pump relay failure, random electrical activation, and battery drain are common.
Common Symptoms
- Vehicle won't start
- Fuel pump runs continuously with key off
- Random electrical malfunctions
- Battery drain overnight
How to Fix
TIPM rebuild service (UpFix, Circuit Board Medics, MAKS TIPM) at $200-$400 is most cost-effective. New TIPM from dealer $800-$1,500 + programming. External fuel pump bypass cable available for fuel pump relay only.

Frequently asked questions
What does P0231 mean on a Chrysler?
P0231 stands for "Fuel Pump Secondary Circuit - Low." This code indicates the engine computer detected a low-voltage condition in the fuel pump's secondary (driver/output) control circuit. Many vehicles control the fuel pump through a relay or a dedicated driver module, and the computer monitors the voltage on that circuit to confirm the pump is being powered correctly. When the feedback voltage stays lower than expected, P0231 sets. Because the fuel pump supplies pressurized fuel to the injectors, this fault can cause hard starting, stalling, or no-start conditions. On Chrysler it is documented across 4 models: 300, Town & Country, Sebring, Aspen.
What are the most common causes of P0231?
The most common causes of P0231 are: Faulty fuel pump relay, Corroded or loose connector at the pump or relay, Damaged or shorted wiring in the pump power circuit, Poor ground for the fuel pump circuit, Failing fuel pump drawing abnormal current, Faulty fuel pump driver module, PCM/ECM internal driver fault (rare). The specific cause varies by vehicle.
How much does it cost to fix P0231 on a Chrysler?
Published repair estimates on Chrysler range from $50 to $1,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
