Check Keyfob Battery and Function
EIS00DBO
1.CHECK KEYFOB BATTERY
1. Remove keyfob battery. Refer toBL-116, "
Remote Controller Battery Replacement".
2. Measure voltage between battery positive and negative termi-
nals, (+) and (-).
NOTE:
Keyfob does not function if battery is not set correctly.
OK or NG
OK >> GO TO 2.
NG >> Replace battery.
2.CHECK KEYFOB FUNCTION
With CONSULT-II

lto front combination lamp RH and LH terminals 2
lto side turn signal lamp RH and LH terminals 2 and
lto rear combination lamp RH and LH terminals 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the left
and right turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
