INSPECTION PROCEDURE
1 CHECK WIRELESS DOOR LOCK FUNCTIONS
(a) Check whether the wireless door lock functions by operating the transmitter s\
witch.
HINT:
When the wireless door LOCK/UNLOCK operation can be performed, it means that\
the wireless signal from
the transmitter is properly input to the integration relay.
NGGo to FLOW CHART (See page 05±1575)
OK
2 CHECK OUTPUTS OF HAZARD WARNING LAMPS
(a) Check that the hazard warning lamps blink when the hazard warning signal\
switch is pressed. NGGo to LIGHTING SYSTEM (See page 65±2)
OK
3 CHECK WIRE HARNESS (FLASHER RELAY ± INSTRUMENT PANEL J/B ASSY)
(a) Disconnect the T10 relay connector.
(b) Disconnect the I14 J/B connector.
(c) Check the resistance between the wire harness side con- nectors.
