SPARK TEST
Inspect the following before performing the spark test.
• Faulty spark plug
• Loose spark plug cap
• Water in the spark plug cap (Leaking the ignition coil
secondary voltage)
• Loose ignition coil connector.
Disconnect the spark plug cap from the spark plug.
Connect a known-good spark plug to the spark plug cap and
ground the spark plug to the cylinder head cover bolt.
PKA/VKA/VYA types:
