U0132Lost Communication With Suspension Control Module A
- Generic OBD-II code · Network
- Turns on the check-engine light
- How the car detects it
- 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.
