G92415t2: CHECK THE IGNITION COIL SUPPLY VOLTAGE CIRCUIT
Disconnect the relevant A bank ignition coil electrical connector(s).
Turn the ignition switch to the ON position.
Measure the voltage between:
Cyl A1. EN051 pin 1, (RW) and GROUND.
Cyl A2. EN052 pin 1, (RW) and GROUND.
Cyl A3. EN053 pin 1, (RW) and GROUND.
Disconnect the relevant B bank ignition coil electrical connector(s).
Measure the voltage between:
Cyl B1. EN054 pin 1, (RW) and GROUND.
Cyl B2. EN055 pin 1, (RW) and GROUND.
Cyl B3. EN056 pin 1, (RW) and GROUND.
Is the voltage greater than 10.5 Volts?
-> Yes : GO to PINPOINT TEST G92415T3: CHECK THE IGNITION COIL GROUND CIRCUIT.
-> NO : REPAIR the relevant ignition coil supply voltage circuit. For additional information, refer to. CLEAR the DTCs. TEST the system for normal operation.
G92415t3: CHECK THE IGNITION COIL GROUND CIRCUIT
Switch the ignition to the OFF position.
Disconnect the relevant A bank ignition coil electrical connector(s).
Measure the resistance between:
Cyl A1. EN051 pin 3, (B) and GROUND.
Cyl A2. EN052 pin 3, (B) and GROUND.
Cyl A3. EN053 pin 3, (B) and GROUND.
Disconnect the relevant B bank ignition coil electrical connector(s).
Measure the resistance between:
Cyl B1. EN054 pin 3, (B) and GROUND.
Cyl B2. EN055 pin 3, (B) and GROUND.
Cyl B3. EN056 pin 3, (B) and GROUND.
Is the resistance less than 5 ohms?
-> Yes : GO to PINPOINT TEST G92415t4.
-> NO : REPAIR the relevant ignition coil ground circuit. For additional information, refer to. CLEAR the DTCs. TEST the system for normal operation.
G92415t4: CHECK THE CONTINUITY OF THE IGNITION COIL TRIGGER SUPPLY CIRCUIT
Disconnect the ECM electrical connector EN016.
Check the continuity of the ignition coil trigger supply circuit between the relevant ignition coil electrical connector(s) and the ECM electrical connector:
Cyl A1. EN051 pin 4, (GU) and EN016 pin 87, (GU)
Cyl A2. EN052 pin 4, (GW) and EN016 pin 88, (GW)
Cyl A3. EN053 pin 4, (GR) and EN016 pin 89, (GR)
Cyl B1. EN054 pin 4, (GU) and EN016 pin 61, (GU)
Cyl B2. EN055 pin 4, (GW) and EN016 pin 62, (GW)
Cyl B3. EN056 pin 4, (GR) and EN016 pin 63, (GR)
Is the resistance less than 5 ohms?
-> Yes : GO to PINPOINT TEST G92415t5.
-> NO : REPAIR the ignition coil trigger supply circuit between the relevant ignition coil electrical connector(s) and the ECM electrical connector. CLEAR the DTCs. TEST the system for normal operation.
G92415t5: CHECK THE CONTINUITY BETWEEN THE IGNITION COIL AND THE ECM
Check the continuity of the ignition coil diagnostic signal circuit, between the ignition coil electrical connector(s) and the ECM electrical connector:
Cyl A1. EN051 pin 2, (YG) and EN016 pin 131, (YG)
Cyl A2. EN052 pin 2, (YG) and EN016 pin 131, (YG)
Cyl A3. EN053 pin 2, (YG) and EN016 pin 131, (YG)
Cyl B1. EN054 pin 2, (YG) and EN016 pin 132, (YG)
Cyl B2. EN055 pin 2, (YG) and EN016 pin 132, (YG)
Cyl B3. EN056 pin 2, (YG) and EN016 pin 132, (YG)
Is the resistance less than 5 Ohms?
-> Yes : INSTALL a new ECM. For additional information refer to Before replacing a ECM, contact Dealer technical support. CLEAR the DTCs. TEST the system for normal operation.
-> NO : REPAIR the circuit between the ignition coil electrical connector(s) and the ECM electrical connector. CLEAR the DTCs. TEST the system for normal operation.
