2004 Galant
SUBJECT
ETACS-ECU REPLACEMENT FOR EXCESSIVE 'IGNITION OFF' BATTERY DRAIN & 'NO START'
PURPOSE
This campaign bulletin contains instructions for replacing a faulty ETACS unit on certain 2004 model year Galant vehicles.
BACKGROUND INFORMATION
Symptom
Affected vehicles may exhibit a dead battery condition. This will usually happen after the vehicle has sat idle for 7 to 10 days. Vehicles driven daily will not typically exhibit the condition.
Cause
A software programming error in the ETACS-ECU causes the vehicle's electrical system to draw excessive current when the ignition switch is in the OFF position. The ETACS-ECU software error in no way affects the normal operation and driving of the vehicle.
Remedy
Replace the ETACS-ECU on affected vehicles with a new part which has the correct software programming.
Customer Notification
A letter will be sent to all registered owners asking them to return their vehicle to their Mitsubishi Motors dealer for ETACS-ECU replacement.
Dealer Action
Check the VIN number of each suspected vehicle to verify that this service campaign applies. Replace the ETACS-ECU on any affected customer's vehicle and on any vehicle you have in your dealership inventory. Contact any purchaser of recently sold vehicles and have them bring their vehicle in for repair. Recent sales may not have been registered in time for the customer notification letter. For US dealers, a list of vehicles in your dealership inventory at the time of this campaign is included with this bulletin.
AFFECTED VEHICLES
2004 Galant built through February 4, 2004 (up to VIN-----4E097247)
PROCEDURE
IMPORTANT
When scheduling a service appointment to do this repair on an affected vehicle, please ask the customer to bring all remote keyless entry transmitters so they can be reprogrammed to the new ETACS-ECU
Refer to Group 54 in the service manual for ETACS-ECU replacement information.
1. Charge the battery if it does not start the vehicle. Normally, the battery will not require replacement for this condition. After the battery is fully charged, check to make sure it starts the vehicle. If so, proceed with step 3.
2. If the battery starts the engine properly, proceed with step 3.
3. Remove the lower instrument panel cover on the driver's side and replace the ETACS-ECU with the new part (P/N 8637A052). Reinstall the instrument panel cover.
4. Reprogram all the vehicle's remote keyless entry transmitters.
a. Check that the doors lock normally when the key is used.

NOTE:
The hazard warning light switch is a toggle switch.
e. Press a transmitter button, then press it again two times within 10 seconds of the first press. This will reprogram the transmitter.
f. The the transmitter is programmed, the ETACS-ECU automatically locks and unlocks the doors once.

IMPORTANT
Transmitter registration/reprogramming will cancel under the following conditions:
^ When four transmitters have been programmed.
