P0358 means Ignition Coil H Primary/Secondary Circuit Malfunction. The DME records it when the primary electrical response or resulting combustion from coil H is implausible; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0357 means Ignition Coil G Primary/Secondary Circuit Malfunction. The DME records it when coil G does not produce the expected primary-current signature or cylinder contribution; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0356 means Ignition Coil F Primary/Secondary Circuit Malfunction. The DME records it when the DME sees an incorrect electrical load or combustion response from coil F; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0355 means Ignition Coil E Primary/Secondary Circuit Malfunction. The DME records it when coil E primary current or secondary ignition performance becomes implausible during DME actuation; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0354 means Ignition Coil D Primary/Secondary Circuit Malfunction. The DME records it when the electrical load or combustion contribution for coil D fails to match its command; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0353 means Ignition Coil C Primary/Secondary Circuit Malfunction. The DME records it when coil C shows an implausible primary load or secondary ignition response when commanded; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0352 means Ignition Coil B Primary/Secondary Circuit Malfunction. The DME records it when the primary current or combustion response of coil B does not follow the DME command; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0276 means Cylinder 6 Injector Circuit Low. The DME records it when the cylinder 6 injector circuit is pulled low or draws an implausible electrical load; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0274 means Cylinder 5 Injector Circuit High. The DME records it when the cylinder 5 injector circuit remains electrically high or presents an open load; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0273 means Cylinder 5 Injector Circuit Low. The DME records it when the cylinder 5 injector current or voltage indicates a persistent low-circuit condition; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0271 means Cylinder 4 Injector Circuit High. The DME records it when the cylinder 4 injector circuit stays high or fails to sink current when injection is commanded; diagnosis must prove the named circuit or mechanism before parts are replaced.
P0270 means Cylinder 4 Injector Circuit Low. The DME records it when the cylinder 4 injector control circuit is held low or loads the driver beyond its expected range; diagnosis must prove the named circuit or mechanism before parts are replaced.
