Code 32 DC-DC Converter System

Code No.31, 32 DC-DC converter system


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

SDU out of order








Caution

1. 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.

2. To unlock the SDU connector, put a flat tip screwdriver on the lock spring (metallic portion) of the lock lever as shown, and press it horizontally toward the inside of the unit. In this case, do not force the lock lever up. Do not put the flat tip screwdriver in the clearance between the lock lever and lock spring (metallic portion).

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