Diagnostic Trouble Code (DTC) P0353 Ignition 3 Control Circuit
D06RW072
Circuit Description
The powertrain control module’s (PCM) control circuit 3
provides a zero-volt or a 5-volt output signal to the ignition
coil. The normal voltage on the circuit is zero volts. When
the ignition coil receives the 5-volt signal from the PCM, it
provides a ground path for the B+ supply to the primary
side of the number 3 ignition coil. When the PCM shuts off
the 5 volts to the ignition coil, the ignition coil turns “OFF.”
This causes the ignition coil primary magnetic field to
collapse, producing a voltage in the secondary coil which
fires the spark plug.
The circuit between the PCM and ignition coil is monitored
for an open circuit, short to voltage, and short to ground.
When the PCM detects a problem on ignition control
circuit 3, it will set a DTC P0353.
Conditions for Setting the DTC
The ignition is “ON.”
The engine is turning, determined by the 58X
crankshaft position input signal.
The output voltage is not equal to 5 volts when output
is “ON.”
The output voltage is not equal to 0 volts when output
is “OFF.”
Twenty test failures occur within 40 samples of
continuous spark events.
Action Taken When the DTC Sets
The PCM will illuminate the malfunction indicator lamp
(MIL) the first time the fault is detected.
The PCM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0353 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.
Diagnostic Aids
Check for the following conditions:

6E–213 ENGINE DRIVEABILITY AND EMISSIONS
Poor connection at PCM – Inspect the harness
connectors for backed-out terminals, improper mating,
broken locks, improperly formed or damaged
terminals, and poor terminal-to-wire connections.
Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
Tech 2 display related to DTC P0353 while moving theconnector and wiring related to the ignition system. A
change in the display will indicate the location of the
fault.
Reviewing the Failure Records vehicle mileage since the
diagnostic test last failed may help determine how often
the condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.
