# Service bulletin TSB\-12\-13\-005

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10170690
- Published by NHTSA: 2020\-01\-25
- Manufacturer's number: TSB\-12\-13\-005
- Manufacturer's date: 2012\-11\-13
- NHTSA component: ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING

## NHTSA's summary

Some affected vehicles may display an illuminated MIL with DTC P0420: Warm Up Catalyst Efficiency Below Threshold, recorded in the ECM. An incorrect parameter in the judgment criteria may cause a false MIL \(mis\-detection of a fault when an abnormal condition is not present\). This TSB provides dealers with a procedure to reprogram the ECM with new software to correct the condition.

- [ATIN\-13\-SC\-004\-A](/bulletins/10174066.md), 2020-04-24, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. A service campaign will be launched December 19, 2013 to update the ECM software programming in certain 2008 \- 2014 Lancer Evolution, 2009 \- 2014 Lancer Ralliart, and 2009 \- 2011 Lancer Sportback Ralliart built before September 25, 2013. This service campaign will be conducted in the U.S. and Puerto Rico. A Service Campaign Bulletin outlining the reprogramming procedure will be available December 19, 2013 on MEDIC and MDL. In certain affected vehicles, normal Electric Throttle Valve \(ETV\) fluctuations may cause actual torque to exceed Permitted Torque at low engine speeds. An improper Permitted Torque threshold may then cause false MIL illumination. A software update optimizes the Permitted Torque threshold value to minimize false MIL illumination.
- [SC\-13\-004](/bulletins/10174064.md), 2020-04-24, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. This Service Campaign Bulletin provides field fix procedures for reprogramming the ECM with new software to address false MIL illumination with torque monitor P1241 \(2008\-2010 models\) or P061A \(2011\-2014 models\) stored in memory.
- [TSB\-12\-13\-006](/bulletins/10170691.md), 2020-01-25, Service bulletin: EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING. 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.
- [TSB\-15\-54\-001](/bulletins/10098884.md), 2017-05-11, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. THIS TECHNICAL SERVICE BULLETIN, PROVIDED TO DEALERS, INSTRUCTS THE DEALER TO UPDATE THE HFM SOFTWARE THAT ALLOWS VOICE RECOGNITION TO COMPLETE BEFORE CONNECTION TO THE PHONE BEGINS, TO RECTIFY THE CONDITION WHERE THE HFM ATTEMPTS A BLUETOOTH CONNECTION WITH A MOBILE PHONE WHILE VOICE RECOGNITION IS BOOTING AT THE SAME TIME. IF THE BLUETOOTH CONNECTION COMPLETES BEFORE VOICE RECOGNITION COMPLETES, VOICE RECOGNITION CANNOT BE USED.
