U0432Invalid Data Received From Multi-axis Acceleration Sensor Module A
- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- Multi-axis acceleration sensor module A is the inertial unit that reports yaw rate plus lateral and longitudinal acceleration to stability control, airbag and assistance systems. U0432 is logged when its frames arrive but fail integrity tests. In GM's 2019 tables the XT4 brake module checks the IMU frames for a rolling count that stops changing and for a checksum mismatch; the failure counter must reach 10, rising by 2 per error, the test runs continuously and is Type C without MIL. Saab's 2011 9-5 list adds subtypes 72 (counter) and 74 (checksum). GM PIT5427 ties U0432 with ABS, AWD and suspension warnings on 2010-15 Equinox and Terrain to a corroded X411 connector; FCA lists it among faults addressed by a PCM flash for the 2017 Pacifica (18-002-19). U0125 is lost contact, U0332 software.
