defogger relay terminalj
3and ground
with CONSULT-II or tester.
Voltage: Battery voltage
OK
cNG
Check the following.
+15A fuse
+Harness for open or
short between rear win-
dow defogger relay and
battery
If NG, repair open circuit or
short to ground or short to
power in harness or con-
nectors.
CHECK INPUT SIGNAL CIRCUIT FOR
OPEN OR SHORT.
1. Disconnect ECM harness connector.
2. Check harness continuity between rear
window defogger relay terminalj
5and
ECM terminalj
96.
Refer to Wiring Diagram.
Continuity should exist.
3. Also check harness for short to ground
and short to power.
OK
cNG
Check the following.
+Harness connectors
E127,M21
+Harness connectors
M50,F5
+Harness for open or
short between rear win-
dow defogger relay and
ECM
If NG, repair open circuit or
short to ground or short to
power in harness or con-
nectors.
CHECK REAR WINDOW DEFOGGER
RELAY.
Refer to EL section.
OK
cNG
Replace rear window
defogger relay.
CHECK INTERMITTENT INCIDENT.
Refer to ªTROUBLE DIAGNOSIS FOR
INTERMITTENT INCIDENTº, EC-125 in
