Diagnostic Trouble Code (DTC) Information IAM-B11A349

Condition

The Integrated Audio Module (IAM) checks the signal in the signal cable from the internal gyro.

The diagnostic trouble code (DTC) is stored if the control module detects that:

The gyro shows +-60 degrees/second for 3 seconds when stationary or less than 180 seconds when travelling.
The voltage is too high.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

Ignition switch position II.

NOTE:

The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
