Question about Hyundai Sonata
P1529 TCU Request for MIL On / Freeze Frame to ECU via CAN
1. This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM. The Freeze Frame Data is stored in the ECM under the P1529 request code. Be sure to retrieve freeze frame data before clearing code P1529 from ECM. 2. Check the transaxle system.
