Part Information:
1) Order the required parts based on the vehicle inspection results. Refer to Page 4.
2) Refer to TSB # 20-01-024H-1 (or latest revision) for parts information
3) Refer to HMA Warranty Policy prior to ordering a reman engine. A standard service engine or
QQH engine is required in certain cases.
Warranty Information:
1) The Campaign 953 Engine ECM Update is only required if new software is available. In this case,
choose one of the following methods:
A) Select a Campaign T3G Op Code with the ECM update included if available OR
B) Submit a separate campaign claim for the ECM update using Campaign 953 op codes (in
addition to submitting applicable T3G op code)
2) Refer to TSB # 20-01-024H-1 (or latest revision) for OP Codes
3) Campaign T3G OP codes for for engine replacement should only be used if engine replacement is
deemed necessary by the service procedure in this TSB. General engine replacement for conditions
outside of those contained in this TSB are not covered by Campaign T3G.
Engine Oil Maintenance Information
Poor oil maintenance reduces the engine oil
lubrication and cooling capacities. As a result,
internal engine parts can be damaged
resulting in abnormal wear to internal engine
parts, excessive carbon deposits, sludge, and
other various conditions. An inspection for
these conditions and others may by required
prior to engine approval.
Piston Ring Deposits
NOTICE
Engine oil is used to lubricate, cool, and
operate various engine parts. Engine oil
changes and engine oil level checks are
required on a regular basis for all engines.
Oil Sludge
Engine oil level checks and top-ups are
recommended if they are needed prior to
the end of an oil change interval.

DTC P1326 – ENGINE INSPECTION / REPLACEMENT (SERVICE CAMPAIGN T3G)
Service Procedure:
1. Save all Freeze Frame Data for diagnosis
purposes. Diagnose all DTCs before
proceeding (excluding P1326).
2. Check for any engine oil on the engine oil
dipstick. Using STUI on the GDS, take and
submit a picture of the dipstick with the VIN in
the background of the photo (RO or last 6 digits
written on paper). VIN must be legible.
Engine oil on the dipstick:
Continue with the Engine Rotation Check
No engine oil on dipstick:
Contact Warranty Prior Approval (PA)
Engine Rotation Check:
NOTICE
1. Rotate the crankshaft with the crank rotator
SST. Measure the force required to turn the
crankshaft with a torque wrench if it doesn’t turn
easily with the SST. If the SST or shop tools do
not fit the specific vehicle type, remove the front
passenger wheel and wheel liner or underbody
tray as needed to rotate the crankshaft.
If the crankshaft rotates normally:
 Proceed to bearing inspection.
PA Approval is required for engine
replacement. Contact PA and refer to
the Dealer Best Practices guide for the
latest requirements for engine approval.
1) A video of the engine rotation check
may be required. Video should include:
 VIN Number (label on door jamb)
 Attempt to rotate the crankshaft
2) Save the crankshaft torque value
If the force required to turn the crankshaft
is greater than 94 lb-ft, save the torque
value for records and:
 If there is NO lower end damage:
o Follow the oil drain procedure
 If there is lower end damage:
o Using STUI in the GDS, submit a
picture of the damage with the
VIN in the background of the
photo (RO or last 6 digits written
on paper). VIN must be legible.
o Continue
with
the
engine
replacement procedure
o Finish the flowchart on Page 4.
TSB #: 20-01-004H-2
3) A picture of the lower end damage is
required if present
Additional documentation may be
required.
Use STUI on the GDS to take and submit
pictures and videos.
NOTICE
If other engine accessory components
are seized, remove the engine
accessory belt prior to completing the
engine rotation check.

pressures are also indicated with red/blue
decals on the gauges. Using STUI in the GDS,
take and submit a picture of the gauges with
the pressure levels clearly visible and the VIN
in the background of the photo (RO or last 6
digits written on paper) for records.
Shop air supply:
0.36MPa (50 psi) minimum
AP: 0.1 ~ 0.11MPa,
