Code 46 Analog Collision Determination Circuit System.
Code No. 46 Analog collision determination circuit system
The SDU monitors the analog collision determination circuit and outputs this code when failure or abnormal characteristics of the collision determination circuit are detected.
Probable cause of trouble
^ Defective SDU
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 analog collision determination circuit in the SDU is suspected, replace the SDU.
