For a complete wiring diagram Refer to Section 8W.

Diagnostic Test

NGC POWERTRAIN VERIFICATION TEST VER - 5

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 not been programmed, a DTC
will set in the ABS Module, Airbag Module and the SKIM.

NOTE: 3. If the vehicle is equipped with a Sentry Key Immobilizer System, Secret Key data must be updated.
Refer to the Service Information for the PCM, SKIM and the Transponder (ignition key) for programming
information.

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 C-1 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 customer may experience driveability issues if this is not performed.

7. Inspect the vehicle to ensure that all engine components are properly installed and connected. Reassemble and
reconnect components as necessary.

8. Connect the scan tool to the data link connector.

9. Make sure the fuel tank has at least a quarter tank of fuel. Turn off all accessories.

10. If the Catalyst was replaced, with the scan tool go to the Miscellaneous Menu Option

Catalyst Replaced

and

press enter.

11. If a Comprehensive Component DTC was repaired, perform steps 12 - 14. If a 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.

16. If another DTC has set, return to the Engine Electrical Diagnostic List and follow the path specified for that DTC.

NOTE: The PCM can detect and compensate for variances in the engine and its components. To learn these
variations, the PCM uses the input of the actual crankshaft rotation pattern and ideal crankshaft rotation
pattern that has been calibrated into the PCM. The PCM then compares the two patterns. The variation
between the two values is the Adaptive Numerator. If the Adaptive Numerator is not learned by the PCM, the
misfire monitor will not run and the Multi-Cylinder Displacement System (MDS) will not operate. Without
MDS operation, the customer will experience decreased fuel economy. If the customer experiences decrease
fuel economy or after any repair use the scan tool to ensure that the Adaptive Numerator is learned.

Did the OBDII Monitor run successfully and has the Good Trip Counter changed to one or more?

Yes

>> Repair is complete.

>> Check for any related Technical Service Bulletins and/or refer to the appropriate Diagnostic Procedure.

NGC POWERTRAIN VERIFICATION TEST VER - 6

For the Engine circuit diagram (Refer to 9 - ENGINE - SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

Diagnostic Test

NGC POWERTRAIN VERIFICATION TEST VER - 6

1. Install the Miller Tool #8404 Evaporative Emission Leak Detector (EELD) according to the instructions in the pre-
vious DTC table.

2. Set the smoke/air control switch to AIR.

3. Insert the tester’s AIR supply tip (clear hose) into the appropriate calibration orifice on the tester’s control panel
(based on DTC leak size).

4. Press the remote smoke/air start button.

5. Position the red flag on the air flow meter so it is aligned with the indicator ball.

6. When the calibration is complete, release the remote button. The EELD flow meter is now calibrated in liters per
minute to the size of leak indicated by the DTC set in the PCM.

7. Install the service port adapter #8404-14 on the vehicle’s service port.

8. Connect the Air supply hose from the EELD to the vehicle.

9. Press the remote button to activate AIR flow.

NOTE: 10. Larger volume fuel tanks, lower fuel levels or if the vehicle is equipped with a Flow Management
Valve may indicate high flow and will require 4 to 5 minutes to fill.
11. Compare the flow meter indicator ball reading to the red flag.

12. ABOVE the red flag indicates a leak present.

13. BELOW the red flag indicates a sealed system.

NOTE: 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.
15. If the indicator ball shows a leak present, perform the smoke test indicated in the previous test and identify the
leak and repair. Perform this verification test when the repair is complete.

Did the indicator ball indicate the a leak is present?

Yes

>> Repeat the DTC test to identify the leak and repair.

>> Repair is complete.

STANDARD PROCEDURE

TCM QUICK LEARN - 42RLE Only

The quick learn procedure requires the use of the appropriate scan tool.

This program allows the electronic transmission system to recalibrate itself. This will provide the proper transmission
operation. The quick learn procedure should be performed if any of the following procedures are performed:

•

Transmission Assembly Replacement

•

Transmission Control Module Replacement

•

Solenoid Pack Replacement

•

Clutch Plate and/or Seal Replacement

•

Valve Body Replacement or Recondition

To perform the Quick Learn Procedure, the following conditions must be met:

ELECTRONIC CONTROL MODULES - SERVICE INFORMATION

8E - 291

•

The brakes must be applied

•

The engine speed must be above 500 rpm

•

The throttle angle (TPS) must be less than 3 degrees

•

The shift lever position must stay in PARK until prompted to shift to overdrive

•

The shift lever position must stay in overdrive after the Shift to Overdrive prompt until the scan tool indicates
the procedure is complete.

•

The calculated oil temperature must be above 60° and below 200°

TCM ADAPTATION - NAG1 Only

The adaptation procedure requires the use of the appropriate scan tool. This program allows the electronic trans-
mission system to re-calibrate itself. This will provide the proper baseline transmission operation. The adaptation
procedure should be performed if any of the following procedures are performed:

•

Transmission Assembly Replacement

•

Transmission Control Module Replacement

•

Clutch Plate and/or Seal Replacement

•

Electrohydraulic Unit Replacement or Recondition

1. With the scan tool, reset the Transmission adaptives. Resetting the adaptives will set the adaptives to factory

settings.

NOTE: Perform the Coast Down Adaptations first. The Transmission Temperature must be greater than 60°C
(140°F) and less than 70°C (158°F). Failure to stay within these temperature ranges will void the procedure.

2. Drive the vehicle until the transmission temperature is in the specified range.

3. Perform 4 to 5 coast downs from 5th to 4th gear and then 4th to 3rd gear.

NOTE: For Upshift adaptation, the Transmission temperature must be greater than 60°C (140°F) and less
than 100°C (212°F). Failure to stay within these temperature ranges will void this procedure.

4. From a stop, moderately accelerate the vehicle and obtain all forward gear ranges while keeping the Engine

RPM below 1800 RPM. Repeat this procedure 4 to 5 times.

5. Obtaining 5th gear may be difficult at 1800 RPM. Allow the transmission to shift into 5th gear at a higher RPM

then lower the RPM to 1800 and perform manual shifts between 4th and 5th gears using the shift lever.

6. The TCM will store the adaptives every 10 minutes. After completion of the adaptation procedure make sure the

vehicle stays running for at least 10 minutes.

7. It is possible to manually store the adaptives under the 10 minute time frame using the scan tool Store Adaptives

procedure.

REMOVAL

USE THE SCAN TOOL TO REPROGRAM THE NEW POWERTRAIN CONTROL MODULE (PCM) WITH THE
VEHICLES ORIGINAL IDENTIFICATION NUMBER (VIN) AND THE VEHICLES ORIGINAL MILEAGE. IF THIS
STEP IS NOT DONE, A DIAGNOSTIC TROUBLE CODE (DTC) MAY BE SET.

To avoid possible voltage spike damage to PCM, ignition key must be off, and negative battery cable must be dis-
connected before unplugging PCM connectors.
