Various diagnostic tools can help identify a bad ignition coil. Many Hilux owners use an OBD2 scanner to check for misfire codes e.g., P0301-P0306. Spark testers can confirm weak sparks, while multimeters measure coil resistance. Another simple test is swapping coils between cylinders to see if the misfire moves. These methods help pinpoint faulty coils efficiently.
