POWERTRAIN VERIFICATION TEST VER - 5 (DIESEL)
Diagnostic Test
1.POWERTRAIN VERIFICATION TEST VER - 5 (DIESEL)
1. Check if any of the following conditions exist.
2. The ECM has been disconnected or replace.
3. The Battery power has been disconnected.
4. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and
reconnect components as necessary.
5. If any existing diagnostic trouble codes have not been repaired, go to Symptom List and follow path specified.
6. Connect the scan tool to the data link connector.
7. Ensure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.
8. Perform steps 15 through 17 if the PCM has been replaced. Then proceed with the verification. If the ECM has
not been replaced skip those steps and continue verification.
9. If ECM has been changed and correct VIN and mileage have not been programmed, a DTC will be set in ABS
and Air bag modules. In addition, if vehicle is equipped with a Sentry Key Immobilizer Module (SKIM), Secret Key
data must be updated to enable start.
10. For ABS and Air Bag systems: Enter correct VIN and Mileage in ECM. Erase codes in ABS and Air Bag mod-
ules.
11. For SKIM theft alarm: Connect scan tool to data link connector to Theft Alarm, SKIM, Misc. and place SKIM in
secured access mode by using appropriate PIN code for this vehicle. SelectUpdate the Secret Key data. Data will
be transferred from SKIM to PCM.
12. If a Comprehensive Component DTC was repaired, perform steps 10-13. Ifa Major OBDII Monitor DTC was
repaired skip those steps and continue verification.
13. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
14. If there are no new DTC’s, the repair was successful and is now complete.Erase DTC’s and disconnect the
scan tool.
15. If the repaired DTC has reset, the repair is not complete. Check for any related TSB’s or flash updates and
return to the Symptom list.
16. If another DTC has set, return to the Symptom List and follow the path specified for that DTC.
17. With the scan tool, monitor the appropriate pre-test enabling conditions until all conditions have been met. Once
the conditions have been met, switch screen to the appropriate OBDII monitor, (Audible beeps when the monitor is
running).
18. If the monitor ran, the repair was successful and is now complete. EraseDTC’s and disconnect the scan tool.
19. If the repaired OBDII trouble code has reset or was seen in the monitor while on the road test, the repair is not
complete. Check for any related technical service bulletins or flash updates and return to Symptom List.
20. If another DTC has set, return to the Symptom List and follow the path specified for that DTC.

5.POWERTRAIN VERIFICATION TEST 4
NOTE: 1. After completing the Powertrain Verification Test the Transmission Verification Test must be per-
formed.
NOTE: 2. If the PCM has been replaced and the correct VIN and mileage have notbeen programmed, a DTC
will set in the ABS Module, Airbag Module and the SKIM/SKREEM.
NOTE: 3. If the vehicle is equipped with a Sentry Key Remote Entry, Secret Key data must be updated. Refer
to the Service Information for the PCM, SKIM/SKREEM and the Transponder (ignition key) for programming
information. Using the scan tool, program the Secret Key information intothe PCM using the PCM replaced
function under the WCM menu.
NOTE: 4. If this vehicle is equipped with an Electronic Throttle Control system, and the APP Sensors, PCM,
or Throttle Body Assembly have been replaced, use the scan tool to perform the ETC RELEARN function.
NOTE: 5. When replacing an O2 Sensor, the PCM RAM memory must be cleared, either by disconnecting the
PCM C1 connector or momentarily disconnecting the Battery negative terminal.
6. The NGC learns the characteristics of each O2 heater element and these old values should be cleared when
installing a new O2 sensor. The customermay experience driveability issues if this is not performed.
7. Inspect the vehicle to make sure that all engine components are properlyinstalled and connected. Reassemble
and reconnect components as necessary.
8. Connect the scan tool to the data link connector.

10. If the Catalyst was replaced, with the scan tool go to the MiscellaneousMenu Option
Catalyst Replacedand
press enter.
11. If a Comprehensive Component DTC was repaired, perform steps 12 - 14. Ifa Major OBDII Monitor DTC was
repaired skip those steps and continue verification.
12. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.
13. With the scan tool, monitor the appropriate pre-test enabling conditions until all conditions have been met. Once
the conditions have been met, switch screen to the appropriate OBDII monitor, (Audible beeps when the monitor is
running).
14. If the repaired OBDII trouble code has reset or was seen in the monitor while on the road test, the repair is not
complete. Check for any related technical service bulletins or flash updates and return to Engine Electrical Diag-
nostic List.
15. If the conditions cannot be duplicated, erase all DTCs with the Scan tool.

Ye s>>
Repair is complete.
No>>
Check for any related Technical Service Bulletins and/or refer to the appropriate Diagnostic Procedure.
4. With the engine in this position, valve lash can be measured at the following rocker arms:INTAKE 1–2–4 /
EXHAUST 1–3–5. Measure the valve lash by inserting a feeler gauge between the rocker arm socket and cross-
head. Refer to VALVE LASH LIMIT CHART for the correct specifications. If the measurement fallswithinthe
limits, adjustment/resettingis notnecessary. If measurement finds the lashoutsideof the limits, adjustment/
resettingisrequired.
VALVE LASH LIMIT CHART
INTAKE EXHAUST
0.152 mm ( 0.006 in.) MIN. 0.533 mm (0.021 in.) MIN.
0.381 mm (0.015 in.) MAX. 0.863 mm (0.034 in.) MAX.
NOTE:
If measured valve lash falls within these specifications, no adjustment/reset is necessary. Engine operation within
these ranges has no adverse affect on performance, emissions, fuel economy or level of engine noise.
5. If adjustment/resetting is required, loosen the lock
nut on rocker arms and turn the adjusting screw
until the desired lash is obtained:
INTAKE0.254 mm (0.010 in.)
EXHAUST0.660 mm (0.026 in.) Tighten the lock
nut to 24 Nꞏm (18 ft. lbs.) and recheck the valve
lash.
6. Using the crankshaft barring tool, rotate thecrank-
shaftone revolution (360°) to align the damper
TDC mark to the 12 o’clock position.
7. With the engine in this position, valve lash can be
measured at the remaining rocker arms:INTAKE
3–5–6 / EXHAUST 2–4–6. Use the same method
as above for determining whether adjustment is
necessary, and adjust those that are found to be
outside of the limits.
8. Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTAL-
LATION).
9. Connect the battery negative cables.
REMOVAL
1. Disconnect the battery negative cables.
2. Remove the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
3. Disconnect the injector harness connectors at cyl-
inder head cover gasket. Remove all injector sole-
noid nuts. Remove cylinder head cover gasket.
4. Remove injector(s) for cylinder(s) to be serviced.
(Refer to 14 - FUEL SYSTEM/FUEL INJECTION/
FUELINJECTOR-REMOVAL)or(Referto14-
FUEL SYSTEM/FUEL INJECTION/FUEL INJEC-
TOR - REMOVAL).
5. Remove the rocker housing.
6. Remove the rocker arms and crossheads from the
cylinder(s) to be serviced. Mark each component
so they can be installed in their original position.
7. Using the crankshaft barring tool # 7471–B (2), rotate the engine to position the damper mark in the 12 o’clock
position.At this engine position, cylinders #1 and #6 can be serviced.
