Service Data Check

Use the scan tool and the SWS monitor kit to check "DATA LIST" or "FUNCTION DIAG."
This "DATA LIST" or "FUNCTION DIAG." check is applicable for signals, which are transmitted and received through the SWS communication line. For input signals, which are not compatible with the SWS monitor kit, refer to the PULSE CHECK PROCEDURE (by using the scan tool or voltmeter).

The table in the illustration shows the service data and their normal condition, which are displayed during the "DATA LIST."

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 shutdown function. However, the headlight operation does not depend on the ignition switch positions, the scan tool does not display the title "IGNITION SWITCH".

For checking item "HI (High-beam)", the scan tool displays "OFF" on the item No. 2 "Dimmer SW" when the headlights are at high-beam. Therefore, the scan tool should display "ON" momentarily when the dimmer switch is operated.
