DTC C1242/42 IG2 Power Source Circuit: Description
WARNING: This page is about a different car, the 2008 Toyota FJ Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
If there is a problem with the master cylinder solenoid (skid control ECU) power supply circuit, the skid control ECU outputs the DTC and prohibits operation under the fail-safe function. If the voltage supplied to terminal IG2 is not within the DTC detection threshold due to malfunctions in parts such as the battery and generator circuit, this DTC is stored.
