Dodge Caliber. Manual - part 1246

CHECK THE PCM

Replace and program the PCM per the Service Information. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN CONTROL MODULE - REMOVAL)

Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)

Does the DTC reset?

Yes

>> Using the schematics as a guide, check the Transmission Control Module (TCM) pins, terminals, and

connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground
circuits. If no problems are found, replace the TCM per the Service Information. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - REMOVAL)

Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)

>> Test Complete.

INTERMITTENT WIRING AND CONNECTORS

STANDARD PROCEDURE

CVT - PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

For a complete wiring diagram Refer to Section 8W.

Perform the following pre-diagnostic troubleshooting procedures prior to performing any diagnostic test.

Always perform diagnostics with a fully charged battery to avoid false symptoms. The Transmission Control Module
(TCM) requires a system voltage between 9 and 16 volts.

1. Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any

leaks and fill the transmission to the proper fluid level. Refer to the Service Information for the proper repair and
fluid fill procedures.

CAUTION: The CVT Transmission uses a specific green transmission fluid that is substantially different
from standard ATF used in other automatic transmissions. Failure to use the proper fluid will result in
excessive transmission damage or total failure. Refer to the Service Information for the proper fluid type.

2. With the scan tool, read Engine DTCs. If Engine DTCs are present, refer to the Engine (Refer to 9 - ENGINE -

DIAGNOSIS AND TESTING) and perform to the appropriate diagnostic procedure(s) before proceeding.

3. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information.

Diagnose any Pending DTC as a matured DTC.

4. Use the wiring diagram as a guide, inspect the wiring and connectors related to this circuit and repair as nec-

essary.

5. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving

under specific conditions, and after controller diagnostic monitors have run or otherwise know as a Good Trip.

6. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply. Check

for controller software update information. Some conditions can be corrected by upgrading the Engine (PCM) or
Transmission (TCM) controller software.

Did any of the above procedures repair the vehicle?

Yes

>> Testing is complete.

Perform CVT TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AU-
TOMATIC - CVT - STANDARD PROCEDURE)

>> Refer to the identified category and perform the appropriate symptom(s). (Refer to 21 - TRANSMIS-

SION/TRANSAXLE/AUTOMATIC - CVT - DIAGNOSIS AND TESTING)

AUTOMATIC - CVT-ELECTRICAL DIAGNOSTICS

CVT VERIFICATION TEST

Perform the following after completion of a diagnostic repair:

1. Reconnect any disconnected components.

2. With the scan tool, erase all Transmission and Engine DTCs.

3. If the Transmission Control Module or the Transmission has been repaired or replaced, it is necessary to perform

the scan tool Quick Learn Procedure.

4. With the scan tool, display Transmission Temperature. Start and run the engine until the transmission tempera-

ture is HOT, above 43° C or 110° F.

5. Check the transmission fluid and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure.

CAUTION: The CVT uses a specific transmission fluid type that is green in color. Do not use a standard ATF
fluid. Doing so can damage the transmission. Make sure to follow the Service Information fluid type and fill
procedure.

6. Road test the vehicle. With the scan tool, monitor the engine rpm and throttle angle. Drive the vehicle from a

standing start to 45 mph with a constant throttle opening of 20 to 25 degrees with an engine speed above 450
rpm.

7. For a specific DTC, drive the vehicle to the Symptom’s When Monitored/When Set condition to verify the DTC is

repaired.

8. If equipped with AutoStick

, upshift and downshift several times using the AutoStick

feature during the road test.

NOTE: Use the OBDII task manager to run a Good Trip. This will confirm the repair(s) made and to ensure
the DTC has not re-matured.

9. Check for any Diagnostic Trouble Codes (DTCs) during and after the road test.

Did any Diagnostic Trouble Codes set during the road test?

Yes

>> Repair is not complete. Refer to the Transmission category and perform the appropriate symptom(s).
