Q: Is the check result satisfactory?
- YES: Go to Step 2
- NO: Repair the CAN bus lines (Refer to CAN BUS DIAGNOSTICS TABLE ). Then go to Step 6.
- STEP 2. Using scan tool MB991958, check the CVT system data list item 49: Transmission range switch.
- Connect scan tool MB991958 to the data link connector (Refer to HOW TO ERASE DIAGNOSTIC TROUBLE CODES ).
- Turn the ignition switch to the "ON" position.
- Set scan tool MB991958 to data reading mode for CVT system (Refer to
DIAGNOSTIC FUNCTION
).
- Item 49: Transmission range switch.
Q: Is the switch operating properly?
- YES: Go to Step 3.
- NO: Repair the CVT system (Refer to DTC P0705: MALFUNCTION OF TRANSMISSION RANGE SWITCH ). Then go to Step 6.
- STEP 3. Using scan tool MB991958, read the CVT system DTC.

- STEP 4. Using scan tool MB991958, check data list item 88: Neutral switch.
- Connect scan tool MB991958 to the data link connector (Refer to HOW TO ERASE DIAGNOSTIC TROUBLE CODES ).
- Turn the ignition switch to the "ON" position.
- Set scan tool MB991958 to data reading mode for cruise control system (Refer to HOW TO ERASE DIAGNOSTIC TROUBLE CODES
).
- Item 88: Neutral switch.
- When selector lever is at the "P" and "N" position, the display on scan tool MB991958 should be "ON."
- When selector lever is other than "P" and "N" position, the display on scan tool MB991958 should be "OFF."
- Item 88: Neutral switch.
Q: Is the switch operating properly?
- YES: Go to Step 5.
- NO: Replace the ECM [Refer to ENGINE CONTROL MODULE (ECM) ] < 2.0L ENGINE Non-turbo > or [Refer to ENGINE CONTROL MODULE (ECM) ] < 2.4L ENGINE >. When the ECM is replaced, register the encrypted code (Refer to ID registration procedure manual - ID codes registration judgement table) < Vehicle with WCM installed >. Then go to Step 6.
- STEP 5. Check the symptoms.
Q: When the selector lever is moved to "N" position, is the cruise control cancelled?
- YES: It can be assumed that this malfunction is intermittent (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTION ).
- NO: Replace the ECM [Refer to ENGINE CONTROL MODULE (ECM) ] < 2.0L ENGINE Non-turbo > or [Refer to ENGINE CONTROL MODULE (ECM) ] < 2.4L ENGINE >. When the ECM is replaced, register the encrypted code (Refer to ID registration procedure manual - ID codes registration judgement table) < Vehicle with WCM installed >. Then go to Step 6.
- STEP 6. Check the symptoms.
Q: When the selector lever is moved to "N" position, is the cruise control cancelled?
- YES: The procedure is complete.
- NO: Return to Step 1.
