P0232 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.

Fuel pump relay inside TIPM fails, preventing fuel pump activation. Vehicle has full electrical power but won't start due to no fuel delivery. Related to broader TIPM issue, specifically affects ASD/Fuel Pump relay circuits.
Common Symptoms
- No-start condition with full electrical power
- No fuel pump priming sound when key turned on
- Intermittent starting issues
- Vehicle starts sometimes, fails other times
- No fuel pressure at rail
How to Fix
TIPM replacement or professional rebuild focusing on fuel pump relay circuits. Temporary fix: tap on TIPM while starting (may restore connection). Long-term requires TIPM replacement ($700-1,200) or rebuild ($200-400).

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. Same fundamental TIPM design flaw as Town & Country and 300.
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 P0232 mean on a Chrysler?
P0232 stands for "Fuel Pump Secondary Circuit - High." This code means the engine computer has detected a high voltage signal in the fuel pump secondary (control) circuit, indicating the circuit that drives or monitors the fuel pump relay is reading higher than it should. The computer controls fuel pump power delivery through a relay and/or driver module, and a high reading suggests a short to voltage, a stuck relay, or a wiring fault in that control circuit. Depending on the fault, it can cause hard starting, stalling, or a no-start because fuel delivery is disrupted. The problem is typically electrical, in the relay, driver, or wiring, rather than the pump motor itself. On Chrysler it is documented across 4 models: 300, Town & Country, Sebring, Aspen.
What are the most common causes of P0232?
The most common causes of P0232 are: Faulty fuel pump relay (stuck or shorted), Short to voltage in the fuel pump control wiring, Failed fuel pump driver module, Corroded or damaged connectors in the circuit, Faulty fuel pump (internal short), Wiring chafed against the body or harness short, Faulty PCM/ECM (rare). The specific cause varies by vehicle.
How much does it cost to fix P0232 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.
