P0232 on Dodge: How to Diagnose & Fix

The TIPM can develop internal relay failures causing various electrical problems including no-start conditions, fuel pump not activating, horn honking randomly, and other erratic electrical behavior. This is a known Chrysler issue.

The TIPM experiences catastrophic failures affecting multiple systems. Fuel pump relay most common failure, causing vehicle to stall while driving. Other failures include power windows, locks, wipers, cruise control. Can drain battery or cause fires.

Fuel pump relay integrated into TIPM fails, preventing fuel pump activation or causing it to run continuously. Engine stalls due to loss of fuel pressure while driving. Most common TIPM failure mode, can strand drivers unexpectedly.

The TIPM central fuse/relay box controls all vehicle electrical functions. Internal relays, especially fuel pump relay, fail from solder joint cracking due to thermal cycling. Causes random activation of lights/wipers/horn, sliding doors losing power, battery drain, and no-start conditions. Same TIPM design flaw as Chrysler Town & Country. Most severe in 2008 and 2010-2011.

Same TIPM design flaw as other Chrysler/Dodge products. Fuel pump relay failure, random electrical activations, and stalling. Can cause both engine and CVT issues through electrical malfunction.

The TIPM fuel pump relay and other relays fail, causing vehicle stalling while driving and no-start conditions. Same TIPM design flaw as all Chrysler/Dodge products of this era.

The Totally Integrated Power Module (TIPM-7 generation) is the Challenger's central fuse-and-relay box and power-distribution computer, mounted in the engine bay. It manages nearly every electrical circuit, and a single failed solder joint, blown internal circuit-board trace, or — most commonly — a degraded internally-soldered fuel-pump relay can cripple the whole car. Because the fuel-pump (ASD) relay is hard-soldered into the TIPM circuit board (not a serviceable plug-in relay), owners cannot simply swap a relay. The dominant root cause is contamination/degradation of the sealed relay contacts (silicone vapor that hardens into insulation and burns under load) compounded by water/moisture intrusion and corrosion of the board, which is why failures are intermittent and often produce no stored trouble codes. The result is a cluster of seemingly unrelated, hard-to-diagnose faults: a relay stuck OFF causes random no-start, no fuel-pump prime, and mid-drive stalling; a relay stuck ON causes the fuel pump to run continuously and drain the battery overnight. This is the root cause behind the model's worst CarComplaints electrical category — the 2013 Challenger alone has a dedicated "bad TIPM" complaint cluster, with failures averaging around 43,000 miles (reported range roughly 8,000–76,000 miles), well within the life of the car. Critically for Challenger owners, the fuel-pump-relay recall campaigns (NHTSA 15V-115 / Safety Recall R09 and the 2019 redo 19V-813) covered the Durango and Jeep Grand Cherokee — NOT the Challenger. NHTSA's recall list for the Challenger shows only airbag and alternator campaigns, no TIPM recall, so Challenger owners pay out of pocket (commonly ~$700–$1,100). The 2008–2014 (LC-body) cars share the TIPM-7 implicated across the Chrysler/Dodge/Jeep lineup; 2010–2014 see the heaviest complaint volume.
