DTC P1326 – ENGINE INSPECTION / REPLACEMENT (SERVICE CAMPAIGN T3G)

SUBJECT:

Engine Rotation Check:
1. Rotate the crankshaft with the crank rotator
SST. If the SST does not fit the specific vehicle
type, remove the front passenger wheel and
wheel liner or underbody tray as needed to
rotate the crankshaft using standard shop tools.
If the crankshaft rotates:
Proceed to bearing inspection.
If the crankshaft does NOT rotate:
Continue with the engine replacement
procedure and update the Engine ECM
software if a newer version is available.

Bearing Inspection:
1. Connect the main hose (shop air supply) and
test hose to the bearing tool. The other end of
the test hose should be disconnected.
Confirm the shop air pressure and AP/VC pressures
on the bearing tool meet requirements:
Shop air supply:
0.36MPa (50 psi) minimum
AP: 0.1 ~ 0.11MPa,
VC: -73 ~ -83Kpa

2. Remove the engine cover and the 4 ignition
coils.
Tightening Torque (ignition coils):
9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 Ib·ft)

TSB #: 20-01-004H-1

5. Connect the GDS to the vehicle and turn the
ignition ‘ON’.
6. Swipe up on the ‘More’ tab at the bottom of
the GDS home screen. Select the ‘Special
Inspection’ function.

7. Select ‘Bearing Clearance Measurement’ on
the GDS.
8. Enter the vehicle info into the GDS as
prompted then select ‘Next’.
9. Connect the GDS to the clearance gauge
SST (gauge) via Bluetooth:
 Press the “Set’ button (B) on the gauge
to turn it on.
 Press the “Set” (B) and “Mode” buttons
at the same time for about 4 sec until the
“reset” message is displayed.
 Select the gauge in the list of devices on
the GDS. Select the ‘Refresh’ icon (C) if
the gauge doesn’t appear automatically.

C

NOTICE
If more than one device appears in
the list of devices, there is another
device in range. Move away from
the other device to pair the gauge.

11. Follow the instructions on the GDS to start
the test and select ‘Next’.

NOTICE
Do NOT connect the test hose to the
clearance gauge yet.

12. To find TDC compression (TDC), rotate the
crankshaft with the crank rotator SST at least
one cycle (1/2 turn). If the SST does not fit the
specific vehicle type, remove the front
passenger wheel and wheel liner or underbody
tray as needed to rotate the crankshaft using
standard shop tools.
Monitor the value on GDS screen or the
clearance gauge SST while turning the wrench.
Turn the wrench slowly as the value reaches a
max/min value. When the value changes
direction (increasing  decreasing or
decreasing  increasing), stop turning the
crank.
If TDC is difficult to find, refer to the shop
manual: Engine Mechanical System > Timing
System > Timing chain.

NOTICE
Ensure the test hose is disconnected
from the clearance gauge when finding
TDC.
