In the 2013 Scion tC the powertrain control module and engine control module manage engine timing, fuel delivery, and transmission coordination. A failure typically results in loss of communication, stalling, or diagnostic codes such as P0606, indicating internal module malfunction.
When a 2013 Scion tC exhibits symptoms like stalling or a P0606 code, the powertrain or engine control module may need replacement. This guide walks you through locating the module, the labor involved, and what programming is required after installation. By the end, you will understand the steps to restore proper engine management and avoid common pitfalls during the repair.
The powertrain control module in a 2013 Scion tC oversees both engine and transmission functions, translating sensor data into precise actuator commands. It works closely with the engine control module, which fine‑tunes fuel injection and ignition timing. Together they ensure smooth acceleration and fuel efficiency. Understanding their role helps you appreciate why a malfunction can cause no‑start conditions or erratic shifting. replacement engine control modules for 2013 Scion tC are designed to meet the same performance standards as the original units.
The control module sits beside the air cleaner assembly, accessed by removing the cable from the negative battery terminal, the air cleaner cap sub‑assembly, the air cleaner case, and the air cleaner inlet. The factory removal procedure reaches the module after these components are taken off. Labor times are listed as 0.7 hours for removal and replacement of the powertrain control module and 0.7 hours for the engine control module, with an additional 0.5 hour relearn for each module after installation.

Work with the ignition off, and treat the module as static-sensitive: avoid touching the connector pins at any point.
| Operation | Configuration | Book Time |
|---|---|---|
| Powertrain Control Module R&R | All configurations | 0.7 hr |
| Powertrain Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module Relearn | All configurations | 0.5 hr |
| Engine Control Module R&R | All configurations | 0.7 hr |
After installing a new module in a 2013 Scion tC, the factory procedure calls for a powertrain control module relearn of 0.5 hours and an engine control module relearn of 0.5 hours. Flagship One units arrive pre‑programmed to the vehicle’s VIN, so those relearn steps are already completed. a VIN-programmed replacement unit eliminates the need for additional programming time at the shop.
Typical signs of a failed powertrain or engine control module in a 2013 Scion tC include a no‑start condition, intermittent stalling, and loss of communication with scan tools. Drivers may also notice rough idle or unexpected shifting behavior. When the internal fault code internal control module malfunction appears, it points directly to a malfunction within the module itself.
The following internal diagnostic codes are documented for the 2013 Scion tC control modules, providing a quick reference for technicians.
| Code | Meaning | Full Guide |
|---|---|---|
| P0606 | Module processor failure | Full P0606 guide → |
P0606 signals an internal fault within the control module, often requiring replacement to restore proper engine and transmission management.
Factory‑specified relearn procedures are listed, but a VIN‑programmed replacement from Flagship One eliminates the need for that step.
The labor guide assigns 0.7 hours for removal and replacement, plus an additional 0.5 hours for the required relearn.
When the control module fails, you can choose a new factory‑spec unit or a refurbished replacement that meets the same performance criteria. Both options restore the vehicle’s engine management, but a refurbished unit may offer cost savings while still delivering reliable operation for your 2013 Scion tC.

Flagship One stocks a refurbished, VIN-programmed PCM for the 2013 Scion tC with a lifetime warranty, free shipping and no core charge. The full Scion tC module lineup covers other engine configurations as well.
Replacing the powertrain or engine control module on a 2013 Scion tC can resolve stalling and code issues. Consider your repair options and ensure proper installation to keep your vehicle running smoothly.
