DESCRIPTION The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2). When the skid control ECU (brake booster with master cylinder assembly) detects improper installation of the yaw rate and acceleration sensor (airbag ECU assembly) or an abnormality in the difference between the yaw rate sensor value and the control value estimated based on the acceleration sensor, steering angle sensor and speed sensor signals, DTC C1436 is stored.
HINT: DTC will be output when conditions for either of the patterns in the table above are met. CAUTION / NOTICE / HINT NOTICE: After replacing or reinstalling the yaw rate and acceleration sensor (airbag ECU assembly), perform yaw rate and acceleration sensor zero point calibration after clearing previously calibrated data.
