Q: What does code P1530 mean?

Ignition Timing Adjustment Switch Circuit Fault. P1530 on Suzuki vehicles indicates the powertrain control module (PCM) has detected an abnormal voltage signal from the ignition timing adjustment switch circuit, which is used to set base ignition timing during service. The PCM expects a specific voltage when the switch is in the adjustment mode, and it flags the code when the signal is out of range, stuck, or missing.
