Code 52 is for low or loss of battery voltage. It is possible that the battery voltage spiked low during a cold start and the light came on. You should have your battery tested. If the battery is good you may have a problem with the wiring circuit losing voltage.
The air bag diagnostic monitor measures the voltage at C209 14, circuit 937 (R/W), of the air bag diagnostic monitor. Voltage at C209 14, circuit 937 (R/W), should be equal to battery voltage. If the voltage at C209 14, circuit 937 (R/W), drops to less than 8 volts, the air bag diagnostic monitor will flash a lamp fault code (LFC) 12on the air bag indicator. If the voltage at pin C209 14, circuit 937 (R/W), drops to less than 5 volts, the diagnostic trouble code (DTC) B1867 will also be stored in memory. Any fuse other than 10 A may ca adidas flux use disarming failure and may result in danger to the occupants of the vehicle. Do not attempt to replace the 10 A fuse 2 unless the air bag system first has been deactivated. NOTE: If a short to ground exists on any of circuits 607 (LB/O), 614 (GY/O), 615 (GY/W), or 616 (PK/BK), leading to a LFC 13 or 53 and DTC B1913; or, similarly, a short to ground exists on any of circuits 617 (PK/O), 619 (PK/W), 624 (Y/W), or 625 (Y/LG), leading to a LFC 14 or 54 and DTC B1914, the air bag diagnostic monitor will activate an internal solid state switch at C209 13 of the air bag diagnostic monitor. This causes the battery fuse 2 (10 A) to blow, thus disarming the air bag system and preventing inadvertent air bag deployment. A short to ground on the battery feed circuit between the fuse 2 (10 A) and C209 13, circuit 937 (R/W), or C209 14, circuit 937 (R/W), of the air bag diagnostic monitor.
AlvinC answered a question about my Ford truck that only someone with an in depth knowledge of his subject would have known what was going on.
Rich DBecause of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me. Thanks again to your service.
Jason V. Thanks, and be sure that I’ll be back whenever I need a question answered in a hurry.

used your se adidas flux rvice this weekend with “Trecers” help. thank you ,thank you, thank you. replaced an A/C fan motor. Local Auto Zone had part. $15.00 “tracer” fee and $40.00 for parts, I saved several hundreds of dollers at a shop. i will
recommend you and use you in the future.

9 dollars, 2 hours of my time, and I drove away. Your diagnosis was right on the mark. Thank you so much.
