SUBJECT: ECM Reprogramming Availability for DTCs
P0017 & P0019
Diagnostic Procedures for DTCs P0016, P0017,
P0018 and P0019

INTRODUCTION
This Bulletin announces a diagnostic procedure and the availability of updated ECM reprogramming
files to address DTCs P00 17 and P00 19. The diagnostic procedure is also applicable to DTCs P00 16
and P0018.

COUNTERMEASURE IN PRODUCTION
A logic change was incorporated into production in mid-December, 2012 starting with the following VINs:
MODEL
lmpreza and
XV Crosstrek

TYPE
4-0oor
5-0oor

STARTING VIN NUMBER
0*019203
0*826233

SERVICE PROCEDURE/ INFORMATION
NOTE: The Flow Charts on pages 4 (Intake) and 5 (Exhaust) summarize the Service Procedures.
•

Be sure to confirm the latest SSMIII software version number, 1.36.50.7 dated January, 2013
(or later) has been installed before performing this procedure. Without it, data for Variable
Valve Timing (VVT) Exhaust Initial Position Leaming Values #1 and #2 will not be available.

•

If the VIN of the vehicle is before the countermeasure, the VVT Leaming Values will not be
accessible until the ECM is reprogrammed with the latest PAK file as outlined in the table on
page 3. Reprogramming procedures can be accessed from the SSMIII User Guide by clicking on
"Help" in the tool bar at the top of the Main Menu screen.

•

Connect the SSMIII to the vehicle.

•

The current CID number of the ECM must be verified using the table on pg. 3 to determine
whether or not it needs to be reprogrammed before proceeding with the following steps.

•

From the Main Menu, select the following options:

Subaru Service Bulletins are intended for use by professional technicians ONLY They
are written to inform those technicians of conditions that may occur in some vehicles, or
to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how
to do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Scroll to the bottom of the Current Data Display list. The last four items will be the VVT Intake and
Exhaust Leaming Values #1 and #2 as shown in the EXAMPLE below. (*CA= Crankshaft Angle
Degrees)

D VVT initial Position Learning Value #1

61.3 *CA

D VVT initial Position Learning Value #2

59.2 *CA

D VVT Ex initial Position Learning Value #1

87.9 *CA

D VVT Ex initial Position Learning Value #2

88.7 *CA

For the INTAKE, the chart above shows values within the Specified Limits (number crankshaft angle
degrees) which are a MINIMUM of 50 and a MAXIMUM of 70 . Check the SSMIII data for VVT
Advance Angle Amount as shown below.
0 VVT Adv. Ang. Amount R

0 deg

0 VVT Adv. Ang. Amount L

0 deg

With the engine at idle and at operating temperature, this value must be "0" . If confirmed to be "0",
proceed with the remaining steps on the INTAKE Flow Chart. If not "0", diagnose and repair the
WVT system per the Service Manual.
For the EXHAUST, the formula shown below must be used to determine if an ECM replacement is
needed. Check the SSMIII data for Exhaust VVT Retard Angle as shown below. The specified range
for this value is "0" +/- 10 degrees .

0 Exh. VVT Retard Ang. R

0 deg

0 Exh. VVT Retard Ang. L

0 deg

First, collect tlie following values from the SSMIII:
•

!A_= Exhaust VVT Retard Angle Value, read with the engine at idle and at operating temperature
(This value may be a positive or negative number.)

•

B= VVT Exhaust Initial Position Leaming Value

•

Formula: C =A+ B - 90 (The 90 value in the formula represents the midpoint of the Specified
Limit range .

Does the value of C = "0" +L- 10 (degrees)?
1. Yes- Perform Inspection Mode and if no DTCs reset, the car is repaired.

2. No- Replace the ECM then follow the remaining steps on the Flow Chart.

Formula Examples:
#1: A= -3 B = 80

-3 + 80 - 90 = -13 (C) so, ECM replacement is required.

#2 A = 2 B = 99.7

2 + 99.7 - 90 = 11. 7 (C) so, ECM replacement is required.

2 + 95 - 90 = 7 (C) In this case, "C" is within the range of+/- 10
#3 A = 2 B = 95
degrees . Perform Inspection Mode per Service Manual and if no DTCs reset, repair is complete.

• If the ECM is determined to oe OK, clear the memory and perform Inspection Mode to confirm
no DTCs reset. If P0016, P00l 7, P0018 or P0019 reset, diagnose per the applicable Service
Manual. If no DTCs reset, the vehicle is repaired.

[I.I the ECM needs to be replaced, install the latest part number available then verify the CID
number is the latest available as shown on the chart below. If the new ECM installed is not the
latest (NEW) part number, update it with the appropriate PAK file as listed below. Following
reprogramming, confirm the CID then matches the NEW CID NUMBER as listed on the chart
below.
