Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code 11: Transaxle Codes Present: Notes
The powertrain control module, used on vehicles equipped w/automatic transaxles, contains an engine control module (EC) and a transaxle control module (TC). These control modules communicate internally over a serial peripheral interface (SPI) bus. When the transaxle control module (TC) detects a malfunction in the automatic transaxle, a code is stored in the transaxle control module's memory and an indication is sent to the engine control module to turn on the malfunction indicator lamp. If the DLC is grounded, the transaxle codes flash on the SHIFT TO D2 telltale.
