B3: Check Amplifier Ground Continuity

NOTE: Disconnection of ALL connectors between the amplifier and the ECM or amplifier and the coils, for any bank, will cause either P1367 or P1368 to be flagged. Ensure that ALL connectors are, or have been, correctly located before condemning an amplifier module.







With EM027 disconnected, measure the resistance between EM027/009 and ground EM008R

- Is the resistance < 0.5 ohms?
Yes
Renew the amplifier module
GO to B4 B4: End
No
