DIAGNOSTIC TROUBLE CODE (DTC) – P0353 IGNITION SIGNAL COIL C FAULT
Circuit Description
The engine control module (ECM) provides a ground for
the electronic spark timing 3 circuit. When the ECM re-
moves the ground path of the ignition primary coil, the
magnetic field produced by the coil collapses. The col-
lapsing magnetic field produces a voltage in the secon-
dary coil, which fires the spark plug. The circuit between
the ECM and the electronic ignition system is monitored
for an open circuit, short to voltage, and low voltage.
When the ECM detects a problem in the spark timing 3
circuit, it will set DTC P0352.
Conditions for Setting the DTC

This DTC can be stored in “key-on” status.

Time of fault fall occurrence is greater than time of the
DIS fall occurrence.
Must receive more than 40 failure within 80 test
cycles.
Action Taken When The DTCs Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and failure records buffers.

A history DTC is stored.

The ECM will default to 6 degree timing.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.

DIAGNOSTIC TROUBLE CODE (DTC) – P1382 ROUGH ROAD DATA INVALID
(NON ABS)
Circuit Description
The VR sensor is used to detecting the road situation.
By sensing difference of wheel rotation duration caused
by bumps or potholes in the road, the Engine Control
Module (ECM) can determine if the changes in crank-
shaft speed are due to engine misfire or are driveline in-
duced. If the VR sensor detects a rough road condition,
the ECM misfire detection diagnostic will be de-acti-
vated.
The VR sensor is located in front–right wheel.
Conditions for Setting the DTC

Vehicle speed is higher than 10km/h(6.21mph).

No Vehicle Speed Sensor error not set.

VR sensor output signal is higher than 0.26.
VR sensor output signal is not change for 30seconds.
Action Taken When The DTCs Sets

The Malfunction Indicator Lamp (MIL) will not illumi-
nate.

The ECM will store conditions which were present
when the DTC was set as Failure Records data only.

This information will not be stored in the Freeze
Frame data.
Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.

DIAGNOSTIC TROUBLE CODE (DTC) – P1382 ROUGH ROAD DATA INVALID
(ABS)
Circuit Description
The wheel speed sensor is used to detecting the road
situation.
As the wheel is rotated, the wheel speed sensor pro-
duces an AC voltage that increase with wheel speed.
The EBCM uses the frequency of the AC signal to calcu-
late wheel speed. The wheel speed sensor is connected
to EBCM by a “twisted pair” of wires. Twisting reduces
noise susceptibility than may cause a DTC to se.If the
wheel speed sensor detects a rough road condition, the
ECM misfire detection diagnostic will be de-activated.
Conditions for Setting the DTC

Vehicle speed is higher than 10km/h(6.21mph).

No Vehicle Speed Sensor error not set.

VR sensor output signal is higher than 0.26.
VR sensor output signal is not change for 30seconds.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will not illumi-
nate.

The ECM will store conditions which were present
when the DTC was set as Failure Records data only.

This information will not be stored in the Freeze
Frame data.
Conditions for Clearing the MIL/DTC

A history DTC will clear after 40 consecutive warm-up
cycles without a fault.

DTC(s) can be cleared by using the scan tool.

Disconnecting the ECM battery feed for more than 10
seconds.
