[FUNCTION DIAGNOSIS]
The table below shows the service data and their normal condition, which are displayed during the "Function Diag." The column "Normal condition" shows values that are shown when each operation is made.

WIPER

Wiper (Part 1):

Wiper (Part 2):

LIGHTING

Lighting (Part 1):

Lighting (Part 2):

NOTE: When checking the input signals (off, tail, low-beam or high-beam), turn the ignition switch to the "ON" position in order to disable the headlight automatic shutoff function. However, since the headlight operation does not depend on the ignition switch positions, the scan tool MB991958 (M.U.T.-III Sub Assembly) does not display the title "IGNITION SWITCH".

For checking item "HEADLIGHT HI", the scan tool MB991958 (M.U.T.-III Sub Assembly) displays "OFF" on the item No.2 "DIMMER SW" when the headlights are at high-beam. Therefore, the scan tool MB991958 (M.U.T.-III Sub Assembly) should display "ON" momentarily when the dimmer switch is operated.

TURN SIGNAL

Turn Signal:

BUZZER

Buzzer:

NOTE: The headlight automatic shutoff function operates approximately one second after the lighting monitor tone alarm starts sounding, and then the tone alarm ceases sounding.

SUNROOF

Sunroof:

PULSE CHECK

1. The input signals (signals other than SWS communication line signals), which are compatible with the SWS monitor by using the scan tool MB991958 (M.U.T.-III Sub Assembly) or voltmeter, can be confirmed by the Pulse Check.
2. Use the scan tool MB991958 (M.U.T.-III Sub Assembly) or voltmeter to check the following input signals.

NOTE: If a problem is found in the Pulse Check, refer to Input Signal Chart. Input Signal Chart
