Discussion:
This bulletin involves replacing the Central Timer Module (CTM) with a revised part.

Symptoms:
 Strong electromagnetic fields or devices that transmit signals in the 315 Mhz range may cause the Central Timer Module (CTM) to intermittently lock up. CTM lock-up may cause a variety of customer complaints including:

• Remote Keyless Entry Malfunction o Interior Lights Will Not Come On
• Intermittent Wipers Will Not Function
• Chime Malfunction
• Power Door Lock Malfunction
• Remote Radio Switch Malfunction (if equipped)
• Heated Seat Malfunction (if equipped)
• Engine Will Not Start (if equipped with Vehicle Theft Alarm)
• No Communication With The DRBIII (No Response from CTM)

Essentially, all CTM controlled devices will not function if the CTM locks-up.

Customers that do experience this condition may:

• have their vehicle equipped with after-market accessories that emit strong electromagnetic signals such as high output Citizen Band (CB) radios or Two-Way radios.
• be equipped with transmitting devices that operate in the 315 Mhz range such as older analog garage door openers.
• live or drive near devices that emit strong electromagnetic signals such as two-way radio communication towers utilized by the military, law enforcement, etc.

Diagnosis: 
If the vehicle exhibits one or more of the conditions identified under Symptom/Condition, pull fuse 13 (power door lock fuse) for one (1) minute. Re-insert fuse 13. If the condition is no longer present, perform the Repair Procedure. If the condition still exists, further diagnosis is necessary, Refer to the appropriate Body Diagnostic Procedures Manuali or the service information available in MDS2 for additional information. If the customer indicates that they may have experienced one or more of the above conditions but were able to correct the condition by removing power to the CTM (pull fuse 13 - power door lock fuse or disconnecting the battery) and the condition cannot be duplicated, perform the Repair Procedure. Due to the nature of this issue, it may be difficult to re-create the customer's complaint
