What U0132 means
U0132 is set when a module stops receiving suspension control module A, the controller for air springs, ride height or damping. GM names the K5 automatic level control module of 2021 Escalade, Tahoe, Suburban and Yukon with air suspension: it goes silent, a leveling or headlamp service message comes up, and removing two fuses for a few minutes revives it (PIT5795). GM's 2025 EBCM flags missing level-control frames after 250 ms as Type C without MIL. FCA links U0132 on Ram 2500/3500 with rear auto-level air suspension to ASCM software and a lit MIL (TSB 08-175-21). Audi Q5/Q7 and Bentley store U013200 in the gateway, cured by a J775 update or a fuse reset. Module B is U0139. Leveling may stop.
U0132 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0132
- Air suspension or leveling warning in the cluster
- Ride height control or headlamp leveling inoperative
- MIL on some vehicles (e.g. Ram heavy duty)
Common causes of U0132
- Most likelySuspension module locked up, recovers after a power cycle (GM PIT5795, Bentley)
- PossibleSuspension module software, fixed by an update (FCA Ram, Audi J775)
- PossibleFuse, supply or CAN wiring of the suspension module faulty
- Less likelySuspension control module internally failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0132 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 32 | The exact fault in that area. |
What to do next
- Note U0132 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 U0132
What does U0132 mean?
U0132 means "Lost Communication With Suspension Control Module A". U0132 is set when a module stops receiving suspension control module A, the controller for air springs, ride height or damping. It is a generic code, so it means the same on every make.
Is it safe to drive with U0132?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will U0132 fail an emissions test?
U0132 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0132 to fix?
Difficulty: medium. A typical repair takes 0.3 to 4 hours of work. This is a job for a workshop.
Will U0132 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
