Q: Is the wiring harness between front door switch (RH)
connector D-34 (terminal 1) and ETACS-ECU connector
C-218 (terminal 65) in good condition?
YES : Replace the ETACS-ECU. If the functions described
in "CIRCUIT OPERATION" work normally, the input
signal from the front door switch (RH) should be
normal.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. If the
functions described in "CIRCUIT OPERATION" work
normally, the input signal from the front door switch
(RH) should be normal.
INSPECTION PROCEDURE M-5: Column Switch: ETACS-ECU does not receive any signal from the
taillight switch, the headlight switch, the passing light switch, the dimmer switch or the turn-signal
light switch.
NOTE: This troubleshooting procedure requires the
use of scan tool MB991958 and SWS monitor kit
MB991813. For details on how to use the SWS mon-
itor, refer to "How to use SWS monitor
