WINDSHIELD INTERMITTENT WIPER INTERVAL CHECK
Required Special Tools
- MB991958: Scan Tool (MUT-III Sub Assembly) MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
If the windshield intermittent wiper interval control is operated, and/or vehicle speed changes, the wiper interval should change.
| CAUTION | To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. |
Scheme 67
- Connect scan tool MB991958 to the data link connector.
- Turn the ignition switch to the "ON" position.
- Operate scan tool MB991958 according to the procedure below to display "Simulated Vehicle Speed Output." Select "SYSTEM SELECT." Select "SWS." Select "Simulated Vehicle Speed Output."
- Holding the windshield intermittent wiper interval control, input the simulated vehicle speed with scan tool MB991958 and check that the wiper interval changes as the vehicle speed changes.
- If not, carry out the troubleshooting. Refer to «SYMPTOM CHART»(ref-308263-S16536086792009020200000) .

- Installation position. Attach each mark to the position shown in the illustration.
- Installation procedure Use 3M(tm) AAD Part number 8906 or equivalent to clean the mark installation surfaces on the body. CAUTION: When attaching the marks, the ambient temperature should be 20-38°C (60-100°F) and the air should be completely free of dust. If the ambient temperature is lower than 20°C (60°F), the marks and the places on the vehicle body where the marks are to be attached should be heated to 20-38°C (60-100°F). Peel off the protection sheet on the back of the marks to affix it in position.

HEATED DOOR MIRROR CHECK
| CAUTION | When relocating the car between locations with extremely different temperatures (warm and cold), leave the car in the location for a while to adapt to the temperature prior to checking it. |
Check to see that the resistance shown in the graph is almost satisfied when measuring the resistance of terminal 1 and 3 of the door mirror connectors.
If the resistance is not within the specified range, replace the door mirror.
