What U0287 means
An electric transmission fluid pump with its own control electronics keeps hydraulic pressure available whenever the engine stands still, in auto stop or electric driving. Stellantis calls it transmission fluid pump module 1; the TCM sets U0287 when it stops responding. On 2021–2025 Jeep Wrangler and Grand Cherokee 4xe, TSB 21-041-26 links the code with MIL and limp mode to a failed in-pan pump, and 08-082-25 traces cases to a damaged high-voltage cable whose noise reaches the pump circuit. The 2026 Compass with 8F30 gets a new pump and TCM software (21-058-26), with stop-start off and a service transmission message. Hyundai sets U028700 in the pump itself on the 2.5 Santa Fe and Tucson with eight-speed automatic, disabling Idle Stop and Go (26-AT-002H).

Symptoms of U0287
- Malfunction indicator lamp and service transmission or hybrid message
- Engine stop-start disabled
- Limp mode on plug-in hybrids
Common causes of U0287
- Most likelyElectric fluid pump or its integrated electronics failed
- PossiblePump connector not fully latched
- PossibleDamaged high-voltage cable inducing interference on the pump circuit (hybrids)
- Less likelyTransmission control module software outdated
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0287 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 87 | The exact fault in that area. |
What to do next
- Note U0287 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0287
What does U0287 mean?
U0287 means "Lost Communication With Transmission Fluid Pump Module A". An electric transmission fluid pump with its own control electronics keeps hydraulic pressure available whenever the engine stands still, in auto stop or electric driving. It is a generic code, so it means the same on every make.
Is it safe to drive with U0287?
Drive gently and only to a workshop. With U0287 the car can go into limp mode (reduced power) to protect itself.
Will U0287 fail an emissions test?
Yes, it can. U0287 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U0287 to fix?
Difficulty: hard. A typical repair takes 0.5 to 7.5 hours of work. This is a job for a workshop.
Will U0287 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
