2	On the menu "Diagnostic Trouble Codes Information" ("Information about codes") select command "Request DTC by Status" ("Request codes by status"). Perform a status code query. Is the code U0401 displayed?	-	Go to Step 3	Eliminate intermittent contact in the electrical connector (see "Checking harnesses and electrical connectors" in this section)
3	Turn off the ignition. Disconnect the Engine Control Module (ECM) and Transmission Control Module (TCM). Check for an open or short to ground in the wire between pin 17 of the TCM connector J1 and pin 30 (LD9) of the ECM connector J1. (pin 84 of connector J1: LLW, pin 42 of connector J2: LU1) Malfunction detected?	-	Go to Step 5	Go to Step 4
4	Check for an open or short to ground in the wire between pin 7 of the TCM connector J1 and pin 49 of the ECM connector J1. (pin 83 of connector J1: LLW, pin 55 of connector J2: LU1) Malfunction detected?	-	Go to Step 5	Go to Step 6
5	Replace the unshielded twisted pair cable between the TCM and the ECM or, if necessary, repair the connector contact fault. Clear the fault codes using a diagnostic tool. Start the engine and let it idle at normal operating temperature. Let the car run. Does the scan tool display a message indicating that the test was successful?	-	Go to Step 8	Proceed to Step 1
6	Replace the gearbox controller. Clear the fault codes using a diagnostic tool. Start the engine and let it idle at normal operating temperature. Let the car run. After eliminating the codes, perform a test to reproduce the conditions under which the fault occurred. Does the scan tool display a message indicating that the test was successful?	-	Go to Step 8	Go to Step 7
7	Replace the ECM. Clear the fault codes using a diagnostic tool. Start the engine and let it idle at normal operating temperature. Let the car run. After eliminating the codes, perform a test to reproduce the conditions under which the fault occurred. Does the scan tool display a message indicating that the test was successful?	-	Go to Step 8	-
8	Check for additional fault codes. Are there any fault codes identified that have not yet been diagnosed?	-	Go to the table of the corresponding code	The system is working properly

• 3 seconds have passed since the ignition was turned on.
• Emergency mode is disabled.
• Codes U0001, U0140 are missing.

• The transmission controller receives an invalid signal for a request for the upshift and downshift mode for 4 seconds.

• The transmission controller commands the service warning lamp (SVS) to turn on.
• The TCM records the operating status when the "Conditions for Setting the Malfunction Code" are met. The TCM stores this information as a malfunction record.
• The TCM stores the diagnostic trouble code in the TCM memory.
• Switching to (mechanical) the up and down modes are prohibited.

• The TCM turns off the service voltage indicator (SVS) lamp if a malfunction is not detected for three consecutive drive cycles.
• You can clear the code from the controller's memory using a diagnostic tool.
• The TCM clears the diagnostic trouble code from the TCM memory after forty consecutive warm-up cycles without a fault.

• Wiring harness between upshift/downshift switch and BCM.
• Up/Down Mode Switch
• BCM

Step	Operation	Values	Yes	No
1	Turn off the ignition. Connect the diagnostic tool. The engine is stopped. Turn the ignition switch to the ON position. On the menu "Diagnostic Trouble Codes Information" ("Information about codes") of the diagnostic tool select the command "Store Freeze Frame/Failure Records" ("Freeze Frame/Malfunction Recordings"). Save freeze frame/malfunction record data. On the menu "Diagnostic Trouble Codes Information" ("Information about codes") select command "Clear DTC Information" ("Clear code information"). Clear code information. Complete one drive cycle. Winter mode light blinking?	-	Go to Step 2	Eliminate intermittent contact in the electrical connector (see "Checking harnesses and electrical connectors" in this section)
2	On the menu "Diagnostic Trouble Codes Information" ("Information about codes") select command "Request DTC by Status" ("Request codes by status"). Perform a status code query. Is the code U0422 displayed?	-	Go to Step 3	Eliminate intermittent contact in the electrical connector (see "Checking harnesses and electrical connectors" in this section)
3	Test the 12V reference circuit for a short to ground or an open between the up/down mode switch and the BCM. Malfunction detected?	-	Eliminate short to ground or open circuit.	Go to Step 4
4	Check the signal circuit for an open or short to voltage or a short to ground between the up/down mode switch and the BCM. Malfunction detected?	-	Eliminate open circuit, short circuit to supply voltage or short circuit to ground in the signal circuit.	Go to Step 5
5	Check the signal circuit for an open or short to voltage or a short to ground between the up/down mode switch and ground. Malfunction detected?	-	Repair open circuit, short circuit to voltage, or short circuit to ground.	Go to Step 6
6	With the ignition on, check the voltage at the output terminal of the up/down mode switch by changing the position of the gear shift lever. Refer to "Diagnostic Aid". Is the measurement result within the specified range?	-	Replace BCM controller.	Replace the shift control lever assembly.
