Automatic Transmission Diagnostic Procedures: Other Chrysler Pacifica CS

SYSTEM COVERAGE

The diagnostic procedure article covers all 2005 CS vehicles equipped with a 41TE transaxle.

AUTOSTICK FEATURE (IF EQUIPPED)

This feature allows the driver to manually shift the transaxle when the shift lever is moved to the AutoStick position. When in AutoStick mode, the instrument cluster displays the current gear.

HARD CODE

Any Diagnostic Trouble Code (DTC) that is set whenever the system or component is monitored is a HARD code. This means that the problem is there every time the Transmission Control System checks that system or component. Some codes will set immediately at start up and others will require a road test under specific conditions. It must be determined if a code is repeatable (Hard) or intermittent before attempting diagnosis.

ONE TRIP FAILURES

A One Trip Failure, when read from the Transmission Control System, is a hard OBDII (EURO STAGE III OBD) code that has not matured for the full 5 minutes to a hard fault. This applies to codes that will only set after 5 minutes of substituted gear operation.

INTERMITTENT CODE

A diagnostic trouble code that is not there every time the Transmission Control System checks the circuit or function is an a intermittent code. Some intermittent codes are caused by wiring or connector problems. However intermittent gear ratio codes are usually caused by intermittent hydraulic seal leakage in the clutch and/or accumulator circuits. Problems that come and go like this are the most difficult to diagnose, they must be looked for under the specific conditions that cause them.

STARTS SINCE SET COUNTER

For the most recent code, the Starts Since Set counter counts the number of times the vehicle has started since it was last set. The counter will count up to 255 starts. Note that this code only applies to the last or most recent code set.

When there are no diagnostic trouble codes stored in memory, the DRBIII® will display NO DTC'S PRESENT and the reset counter will show "STARTS SINCE CLEAR = XXX

The number of starts helps determine if the diagnostic trouble code is hard or intermittent. - If the count is less than 3, the code is usually a hard code. - If the count is greater than 3, it is considered an intermittent code. This means that the engine has been started most of the time without the code recurring.

QUICK LEARN

A warm-up cycle is defined as sufficient vehicle operation such that the coolant temperature has risen by at least 22°C (40°F) from engine starting and reaches a minimum temperature of 71°C (160°F).

The Quick Learn function customizes adaptive parameters of the control module to the transmission characteristics of a vehicle. This gives the customer improved "as received" shift quality compared to the initial parameters stored in the control module.

Notes about Quick Learn Features

The nature of the Quick Learn function requires that certain features must be taken into consideration.

1. > Quick Learn should generally not be used as a repair procedure unless directed by a repair or diagnostic procedure. If the transmission system is exhibiting a problem that you think is caused by an invalid CVI, you should try to relearn the value by performing the appropriate driving maneuvers. In most cases, if Quick Learn makes a vehicle shift better, the vehicle will return with the same problem.
2. > Before performing Quick Learn, it is imperative that the vehicle be shifted into OD with the engine running and the oil level set to the correct level. This step will purge air from the clutch circuits to prevent erroneous clutch volume values, which could cause poor initial shift quality. > If a new control module is installed on a vehicle with a HOT engine, Quick Learn will cause the control module to report a cold calculated oil temperature. This requires monitoring the calculated oil temperature using the DRBIII®. If the temperature is below 15°C (60°F), the transmission must be run at idle or driven in gear until the temperature goes above 15 C (60°F). If the temperature is above 93C (200°F), the transmission must cool to below 93 C (200°F).
3. > First gear is engaged in overdrive after Quick Learn is completed. Place the vehicle in park after performing Quick Learn. The Quick Learn function should be performed: Upon installation of a new service control module After replacement or rebuild of internal transmission components or the torque converter If one or more of the clutch volumes indexes (CVI's) contain skewed readings because of abnormal conditions. To perform the «QUICK LEARN»(ref-247417-S25892895542007012400000) procedure, the following conditions must be met. It is imperative that the vehicle be shifted into OD with the engine running and the oil level set to the correct level. This step will purge the air in the clutch circuits to prevent erroneous clutch volume values, which could cause poor initial shift quality. Place the selector lever in neutral. The brakes must be applied. The engine must be idling. The throttle angle (TP sensor) must be less than 3 degrees. The shift lever position must stay in neutral until prompted to shift into OD. The shift lever must stay in OD after the "Shift to Overdrive" prompt until the DRBIII® indicates the procedure is complete. The oil temperature must be between 15 C (60°) and 93 C (200°F).

Note. The above conditions must be maintained during the procedure to keep the procedure from being aborted.

The Quick Learn procedure is performed with the DRBIII® by selecting "Transmission" system then "Miscellaneous" functions, then "Quick Learn". Follow the procedure instructions displayed on the DRBIII®.

CLUTCH VOLUMES

Theory of Operation: The volumes of the transmission fluid needed to apply the friction elements are continuously monitored and learned for adaptive controls. As the clutch friction material wears, the volume of fluid needed to apply the clutch increases. The following are typical clutch volumes, the clutches may be damaged if the volumes are greater or less than the specified below

The LR clutch volume is updated when doing a 2-1 or 3-1 coast down shift. The transmission temperature must be between 21-49 C (70-120°F). The clutch volume should be between 35 and 83.

The 2/4 clutch volume is updated when doing a 1-2 shift. The transmission temperature must be above 43 C (110°F). The clutch volume should be between 20 and 77.

The OD clutch volume is updated when doing a 2-3 shift. The transmission temperature must be above 43 C (110°F). The clutch volume should be between 40 and 150.

The UD clutch volume is updated when doing a 4-3 or 4-2 shift. The transmission temperature must be above 43 C (110°F). The clutch volume should be between 24 and 70.

Transmission Effects: These CVIs that are out of range are usually set with other DTC's, which indicates an internal transmission problem.

Possible Causes

1. > Clutch pack clearance out of spec
2. > Snap ring out of position or broken
3. > Broken return spring
4. > Hydraulic leak into clutch circuit with near-zero volume

ELECTRONIC PINION FACTOR (IF APPLICABLE)

The transmission output speed signal supplies distance pulses to the control module, which are used to calculate speed and mileage. A pinion factor is stored in the control module in order to provide the appropriate distance pulses for other vehicle systems. The pinion factor is programmed into the control module at the assembly plant.

Using the following steps, the pinion factor can be checked and/or reset using the DRBIII®

1. Select Transmission system, then Miscellaneous functions, then Pinion Factor. The DRBIII® will display the current tire size.
2. If the tire size is incorrect, press the Enter key and then select the correct size.
3. Press the Page Back key to exit the reset procedure.

Notes About Electronic Pinion Factor Features

The nature of the electronic pinion factor requires that certain features must be taken into consideration.

1. > If no pinion factor is stored in an installed control module, the vehicle speedometer will not operate, engine speed will be limited to 2300 RPM, and catalyst damage may occur.
2. > Selecting a wrong tire size will cause the speedometer to be inaccurate and will also cause any speed related features to operate improperly.

Note. After replacing the PCM, you must reprogram pinion factor

USING THE DRBIII®

Refer to the DRBIII® users guide for instructions and assistance with reading trouble codes, erasing trouble codes, and other DRBIII® functions.

Scheme 350

DRBIII® ERROR MESSAGES

Under normal operation, the DRBIII® will display one of only two error messages

1. User-Requested WARM Boot
2. User-Requested COLD Boot

If the DRBIII® should display any other error message, record the entire display and call the S.T.A.R. Center.

DRBIII® DOES NOT POWER UP (BLANK SCREEN)

If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage. A minimum of 11 volts is required to adequately power the DRBIII®.

If all connections are proper between the DRBIII® and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRBIII® may be the result of faulty cable or vehicle wiring. For a blank screen, refer to BODY DIAGNOSTIC PROCEDURES .

DISPLAY IS NOT VISIBLE

Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this condition.

SOME DISPLAY ITEMS READ"-"

This is caused by the scrolling the DRBIII® display a single line up or down. The line which was scrolled onto the screen might read "-". Use the page down or page up function to display the information.

TRANSMISSION SIMULATOR (MILLER TOOL # 8333) AND FWD ADAPTER (MILLER TOOL #8333-1 A)

Note. Remove the starter Relay when using the transmission simulator *Failure to remove the Starter Relay can cause a PCM - No Response condition. *The removal of the Starter Relay will also prevent the engine from starting in gear. *The Transmission Simulator will not accurately diagnose intermittent faults.

The transmission simulator, simply put, is an electronic device that simulates the electronic functions of any EATX or NGC controlled transmission (41TE, 41TE, 45RFE, and 545RFE). The basic function of the simulator is to aid the technician in determining if an internal transmission problem exists or if the problem resides in the vehicle wiring or control module. It is only useful for electrical problems. It will not aid in the diagnosis of a failed mechanical component, but it can tell you if the control module and wiring are working properly and that the problem is internal to the transmission.

The ignition switch should be in the lock position before attempting to install the simulator. Follow all instructions included with the simulator. If the feedback from the simulator is in doubt, you can verify the simulators operation by installing it on a known good vehicle. A "known good vehicle" would be defined as a vehicle that does not set any DTC's and drives and shifts as expected.

One important point to remember is that the Simulator receives power from the Trans Relay Output circuit. If the transmission system is in Limp-in (Relay open), the simulator will not operate. This is not really an indication of a problem, but an additional symptom. If the simulator does not power up ("P" led lit), this is an indication that the problem is still present with the simulator hooked up. This indicates that the problem is in the wiring or control module and not the transmission.

Miller Tool # 8333-1A consists of the adapter cables and overlay necessary to adapt the simulator to TE/AE/RLE/LE transmissions.

DISCLAIMERS

All information, illustrations, and specifications contained in this article are based on the latest information available at the time of publication. The right is reserved to make changes at any time without notice.

TECHNICIAN SAFETY INFORMATION

Set the parking brake and block the wheels before testing or repairing the vehicle. If is especially important to block the wheels on front-wheel drive vehicles: the parking brake does not hold the drive wheels.

Some operations in this article require that hydraulic tubes, hoses, and fittings, disconnected for inspection or testing purposes. These systems, when fully charged, contain fluid at high pressure.

Before disconnecting any hydraulic tubes, hoses, and fittings, be sure that the system is fully depres-surized. When servicing a vehicle, always wear eye protection, and remove any metal jewelry such as watchbands or bracelets that might make an inadvertent electrical contact.

When diagnosing a Transmission system problem, it is important to follow approved procedures where applicable. These procedures can be found in 41AE/TE TRANSAXLE . Following these procedures is very important to the safety of individuals performing diagnostic tests.

DRBIII® SAFETY INFORMATION

1. Do not use the DRBIII® if it has been damaged.
2. Do not use the test leads if the insulation is damaged or if metal is exposed.
3. To avoid electrical shock, do not touch the test leads, tips or the circuit being tested.
4. Choose the proper range and function for the measurement. Do not try voltage or current measurements that may exceed the rated capacity.
5. Do not exceed the limits shown in the table. FUNCTION AND INPUT LIMIT FUNCTION INPUT LIMIT Volts 0-500 volts peak AC 0-500 volts DC Ohms (resistance) (1) 0-1.12 megohms Frequency measured Frequency generated 0-10 khz Temperature -58-1100°F -50-600C (1) Ohms cannot be measured if voltage is present. Ohms can be measured only in a non-powered circuit.
6. Voltage between any terminal and ground must not exceed 500v DC or 500v peak AC.
7. Use caution when measured voltage above 25v DC or 25v AC.
8. The circuit being tested must be protected by a 10A fuse or circuit breaker.
9. Use the low current shunt to measure circuits up to 10A. Use the high current clamp to measure circuits exceeding 10A.
10. When testing for the presence of voltage or current, make sure the meter is functioning correctly. Take a reading of a known voltage or current before accepting a zero reading.
11. When measuring current, connect the meter in series with the load.
12. Disconnect the live test lead before disconnecting the common test lead.
13. When using the meter function, keep the DRBIII® away from spark plug or coil wires to avoid measuring error from outside interference.

VEHICLE DAMAGE WARNINGS

Before disconnecting any control module, make sure the ignition switch is in the "lock" position. Failure to do so could damage the module.

When testing voltage or continuity at any control module, use the terminal side (not the wire end) of the connector. Do not probe a wire through the insulation: this will damage the wire and eventually cause the wire to fail because of corrosion.

Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such mistakes can damage fuses or components. Also, a second DTC could be set, making diagnosis of the original problem more difficult.

When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.

ELECTRONIC PINION FACTOR WARNINGS (IF APPLICABLE)

The pinion factor must be set when replacing the control module. Note: The pinion factor is a fixed number and cannot be changed or updated in some vehicle applications. If the pinion factor is not set or incorrectly set, any speed related functions will not operate correctly i.e. speedometer, speed control, rolling door locks, other control modules will be affected that depend on speed information.
