Airbag System

Code No.31, 32 DC-DC converter system

[Explanation]

The SDU monitors the DC-DC converter terminal voltage at all times. These codes are output when the DC-DC converter terminal voltage continues to be higher (code No.31) or lower (code No.32) than a predetermined value for five seconds.

Probable cause of trouble

SRS-ECU out of order

Caution

After the ignition switch has been placed at the LOCK position and the negative (-) terminal of the battery has been disconnected, wait for more than 60 seconds before starting work. Wind a tape around the disconnected (-) terminal for insulation.

Since a defective DC-DC converter in the SRS-ECU is suspected, replace the SRS-ECU.
