To address the P1530 code for the Ignition Timing Adjustment Switch Circuit on a 2001 Cadillac Catera, first, inspect the wiring and connectors for any damage or corrosion. Next, check the ignition timing adjustment switch itself for proper function; it may need replacement. If the wiring and switch are in good condition, you may need to use an OBD-II scanner to clear the code and test drive the vehicle to see if the code returns. If it persists, consider consulting a professional mechanic for further diagnosis.
