

Open circuit between ignition coil No.3 terminal C and PCM terminal 2K



Open circuit between ignition coil No.4 terminal C and PCM terminal 2W



Open circuit between ignition coil No.5 terminal C and PCM terminal 2AA



Open circuit between ignition coil No.6 terminal C and PCM terminal 2AE



Short to power supply between ignition coil No.1 terminal C and PCM terminal 2A



Short to power supply between ignition coil No.2 terminal C and PCM terminal 2F



Short to power supply between ignition coil No.3 terminal C and PCM terminal 2K



Short to power supply between ignition coil No.4 terminal C and PCM terminal 2W



Short to power supply between ignition coil No.5 terminal C and PCM terminal
2AA



Short to power supply between ignition coil No.6 terminal C and PCM terminal
2AE



Short to ground circuit between ignition coil No.1 terminal C and PCM terminal 2A



Short to ground circuit between ignition coil No.2 terminal C and PCM terminal 2F



Short to ground circuit between ignition coil No.3 terminal C and PCM terminal 2K



Short to ground circuit between ignition coil No.4 terminal C and PCM terminal 2W



Short to ground circuit between ignition coil No.5 terminal C and PCM terminal
2AA



Short to ground circuit between ignition coil No.6 terminal C and PCM terminal
2AE



Open circuit between ignition coil terminal A and main relay No.2 terminal D



Ignition coil malfunction
