Aura L4-2.4L (2008)
Alarm Module: Service and Repair
Theft Deterrent Module Replacement
Removal Procedure
Important: Because of how vehicle key information and theft deterrent passwords are stored within the theft deterrent module (TDM), the Set
Up a New Theft Deterrent Module procedure must be performed prior to the removal and replacement of the TDM if the vehicle keys are being
reused. Performing the setup procedure first allows the scan tool to extract the key information and passwords from the old TDM prior to its
removal. Failure to perform this step will result in the failure to learn the existing vehicle keys and new vehicle keys will be required when
replacing the TDM.
Do not use the scan tool for any other programming operations while performing this procedure. Doing so will erase the stored data retrieved
from the original TDM and cause the set-up to fail.
1. Remove the ignition switch. Refer to Ignition and Start Switch Replacement (See: Powertrain Management/Ignition System/Sensors and Switches
- Ignition System/Ignition Switch/Service and Repair).
2. Remove the theft deterrent control module screws.
3. Remove the theft deterrent control module.
Installation Procedure
1. Install the theft deterrent control module.
Notice: Refer to Fastener Notice (See: Service Precautions/Vehicle Damage Warnings/Fastener Notice).
2. Tighten the theft deterrent control module screws.
Tighten the screws to 5 N.m (44 lb in).
