Continuously Variable Transaxle (Cvt): Diagnosis — Suzuki SX4 I рестайлинг (2009-2014)

Precautions in Diagnosing Trouble

Do not disconnect connectors from TCM, battery cable from battery, TCM ground wire harness from engine or main fuse before checking the diagnosis information (pending DTC, confirmed DTC, freeze frame data, etc.) other than permanent DTC stored in TCM memory. Such disconnection will clear memorized information in TCM memory.
Diagnostic information stored in TCM memory can be cleared as well as checked by using SUZUKI scan tool or CAN communication OBD generic scan tool. However, for the permanent DTC, it can not be cleared by using SUZUKI scan tool or CAN communication OBD generic scan tool. (For details for permanent DTC, refer to «ON-BOARD DIAGNOSTIC SYSTEM DESCRIPTION»(ref-514590-S04778591522012112100000) .) Before using scan tool, read its "Operator's (Instruction) Manual" carefully to have good understanding as to what functions are available and how to use it. It is indistinguishable which module turns on MIL because not only ECM but also TCM turns on MIL. (For details for permanent DTC, refer to «ON-BOARD DIAGNOSTIC SYSTEM DESCRIPTION»(ref-514590-S04778591522012112100000) .) Therefore, check both ECM and TCM for DTC when MIL lights on.
When checking TCM for DTC, keep in mind that DTC is displayed on the scan tool as follows depending on the scan tool used. SUZUKI scan tool displays DTC detected by TCM. CAN communication OBD generic scan tool displays DTC detected by both ECM and TCM simultaneously.
When performing the following services, all learned controls which are stored in TCM memory should be initialized after the replacement. Neglecting this initialization may cause excessive shift shock. TCM replacement CVT assembly replacement
Be sure to read «PRECAUTIONS FOR ELECTRICAL CIRCUIT SERVICE»(ref-514549-S41213482522012112100000) before inspection and observe what is written there.
TCM replacement When substituting a known-good TCM, check that all relays and actuators have resistance of specified value. Neglecting this check may result in damage to good TCM.
Communication of ECM, BCM, combination meter, keyless start control module (keyless start model), ABS/ESP® control module, 4WD control module (4WD model), steering angle sensor (ESP® model), Yaw rate/G sensor (ESP® model), SDM (advanced air bag model), ID controller (Canada model), TCM and DLC, is established by CAN (Controller Area Network). For more detail of CAN communication system, refer to «CAN COMMUNICATION SYSTEM DESCRIPTION»(ref-514590-S33647234442012112100000) . Also, be sure to handle CAN communication line with care.

Permanent DTC

In accordance with SAE J1979, TCM stores DTCs that adversely affect vehicle emission (i.e. DTCs with MIL turning on) in a non-volatile RAM (NVRAM) separately from that for pending and confirmed DTCs. This DTC is called a permanent DTC.

Unlike pending and confirmed DTCs, the permanent DTC will not be cleared even when executing the clear command of scan tool or when shutting off the power to TCM. Only when does TCM detect no malfunction in the trouble area of the stored permanent DTC with the condition determined normal the permanent DTC will be cleared. (For permanent DTC clearance, refer to DTC CLEARANCE )

The maximum of four earliest detections of the permanent DTCs will be stored in memory. The DTCs are cleared in the order of completing determination as normal.

Step 2. DTC/Freeze Frame Data Check, Record and Clearance

First, check DTC (current and pending DTC) see DTC Check .

If DTC is indicated, print DTC and freeze frame data or write them down and then clear them see DTC Clearance .

Step 3 and 4. Visual Inspection

As a preliminary step, be sure to perform visual check of the items that support proper function of engine and CVT see Visual Inspection .

In case that there is no DTC at Step 2

Based on information obtained in Step 1. Customer Complaint Analysis and Step 2. DTC/Freeze Frame Data Check, Record and Clearance , confirm trouble symptoms.

In case that there is any DTC at Step 2

Recheck DTC according to "DTC Confirmation Procedure" described in each DTC troubleshooting.

Step 6 and 7. Rechecking and Record of DTC and Freeze Frame Data

Refer to DTC CHECK for checking procedure.

Step 8. CVT Basic Check and CVT Symptom Diagnosis

Perform CVT basic check.
In case there is no faulty part found in inspection procedure of "CVT basic check", perform «CVT SYMPTOM DIAGNOSIS»(ref-514590-S16432607242012112100000) based on symptom found in vehicle checking in the following items. Customer complaint analysis Trouble symptom confirmation

Step 9. Troubleshooting for DTC

Perform applicable DTC troubleshooting and repair or replace faulty parts.

Check for intermittent problem see INTERMITTENT AND POOR CONNECTION INSPECTION .

Check parts related to detected DTC (e.g., wire harness, connector, etc.) see INTERMITTENT AND POOR CONNECTION INSPECTION .

Step 11. Final Confirmation Test

Confirm that the problem symptom has gone and the vehicle is free from any abnormal conditions. If what has been repaired is related to DTC, clear DTC once, perform DTC confirmation procedure and confirm that no DTC is indicated.

DTC Check

Note. In case that MIL turns on, the malfunction(s) is detected in either ECM or TCM and it stores the trouble information (DTC, freeze flame data, etc.) in its memory. According to the varieties of scan tool, check the trouble information as follows. SUZUKI scan tool: It is necessary to check both ECM and TCM separately because the trouble information of both modules can not be read and displayed at once. CAN communication OBD generic scan tool: It is not necessary to check both ECM and TCM separately because the trouble information of both modules can be read and displayed at once.

Prepare CAN communication OBD generic scan tool or SUZUKI scan tool.
Turn ignition switch to OFF position.
Connect scan tool to DLC (1). Special Tool (A): SUZUKI scan tool (SUZUKI-SDT)
Turn ignition switch to ON position.
Read DTC, pending DTC and freeze frame data according to instructions displayed on scan tool and print it down. Refer to scan tool operators manual for further details. If communication between scan tool and TCM is not possible, go to «TROUBLESHOOTING FOR COMMUNICATION ERROR WITH SCAN TOOL USING CAN»(ref-514565-S37119849272012112100000) .
After completing the check, turn ignition switch off and disconnect scan tool from DLC.

Pending and Confirmed DTC

Connect CAN communication OBD generic scan tool or SUZUKI scan tool to DLC.
Turn ignition switch to ON position.
Erase DTC and pending DTC according to instructions displayed on scan tool. Refer to scan tool operators manual for further details. If communication between scan tool and TCM is not possible, go to «TROUBLESHOOTING FOR COMMUNICATION ERROR WITH SCAN TOOL USING CAN»(ref-514565-S37119849272012112100000) .
After completing the clearance, turn ignition switch OFF and disconnect scan tool from DLC. NOTE: Pending and confirmed DTC and freeze frame data stored in TCM memory are also cleared in the following cases. Be careful not to clear them before keeping their record. When power to TCM is cut off (by disconnecting battery cable, removing fuse or disconnecting TCM connectors). When the same malfunction (DTC) is not detected again during 40 engine warm-up cycles. Even though the pending and confirmed DTCs are cleared, the permanent DTC will not be cleared.

Connect CAN communication OBD generic scan tool or SUZUKI scan tool to DLC.
Turn ignition switch to ON position.
Clear the pending and confirmed DTCs.
Select the permanent DTC mode on scan tool. (Refer to scan tool operators manual for details.)
Execute the corresponding DTC confirmation procedure in the DTC diagnostic flow and confirm that the pending and current DTCs cannot be detected. At this time, if the DTC confirmation procedure does not satisfy any of the following conditions, execute the DTC confirmation procedure so as to satisfy such condition. The engine operated for more than 12 minutes. The vehicle driven for more than 6 minutes at more than 45 km/h (28 mile/h). The engine idled for more than 1 minute.
Display the permanent DTC on scan tool and check that the permanent DTC is cleared. If the permanent DTC has not been cleared, repeat step 5 ) again.
