SUBJECT:

This bulletin supercedes TSB−11−13−007, issued June, 2011, to correct the subject, include
Lancer Evolution SST, Lancer and Lancer Sportback Ralliart models, clarify instructions for
performing mechanical checks and change Warranty Information. Changes are italicized and
indicated by A .

PURPOSE
Some affected vehicles may display ! ENGINE SYSTEM SERVICE REQUIRED on the MID and DTC
P0012 may be recorded in ECM memory, but the MIL is not illuminated. An incorrect parameter in the
judgment criteria may cause mis−detection of a fault even though the timing chain elongation rate remains
within the specified allowance.

"

This TSB provides a procedure to reprogram the ECM, confirm the oil control valve and timing chain are
not at fault, and reset the timing chain learned value.

"
"

IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated with DTCs listed
in the ECM memory (before reprogramming), diagnose and repair those DTCs per the service manual
before reprogramming. DO NOT reprogram the ECM until the reason(s) for DTCs being set is corrected.

AFFECTED VEHICLES
2008−2011 Lancer Evolution built before January 27, 2011
2009−2011 Lancer Ralliart built before January 27, 2011
2009−2011 Lancer Sportback Ralliart built before January 27, 2011

"

REQUIRED OPERATIONS
"

NOTE: This revision affects only written procedures in the following instructions. Affected
vehicles that were previously reprogrammed for this condition DO NOT require
additional reprogramming.
1. Confirm MUT−III software contains the latest reprogramming database.
2. Reprogram the ECM with new software per the Reprogramming Procedure.

"

If the timing chain is elongated, replace ONLY the chain as described in step 3,
above. DO NOT replace any other related parts (e.g. timing chain tensioner, VVT
sprocket, chain guide, etc.) unless they are significantly worn or damaged.
4. Reset the Timing Chain Learned Value as described in Group 00 − General — Timing Chain
Maintenance, of the service manual.

"

! CAUTION

"

3. Visually check timing chain elongation using procedures described in Group 11 − Engine, of the
service manual. If the timing chain is elongated, replace it and the oil pump chain.

5. Perform “Erase and Read All DTCs.”
6. Perform a test drive to confirm DTCs do not return.

REPAIR PROCEDURE
NOTE: Reprogramming the ECM with the latest database (i.e.11101) includes all past and current
reprogramming for TSBs on affected vehicles. You do not need to reprogram the ECM for each
TSB.
1. Check the underside of the hood to verify there is no “Authorized Modification” label (see page 12 for
example) previously installed to indicate this reprogramming has already been completed. If a label
is present and the “ROM ID #” on the label matches the “New S/W Part No.” in the ECM
Reprogramming Chart on page 2, the ECM is at the latest level and reprogramming is not necessary.
For MEDIC 3 users only: (MUT−III users go to step 4)
2. Verify your MEDIC 3 is at version 3.1 and at update 085
or higher.
If your MEDIC−3 update is at least 085, continue with
the Reprogramming Procedure on page 5.
If your MEDIC 3 update is below 085, update your
MEDIC 3 as follows.
