CHECK INPUT SIGNAL CIRCUIT.
1. Turn ignition switch to ªLOCKº position.
2. Disconnect accelerator work unit har-
ness connector and ECM harness con-
nector.
3. Check harness continuity between
accelerator work unit terminalq
3and
ECM terminal
435. Refer to wiring
diagram.
Continuity should exist.
Check harness for short-circuit.
OK
ENG
Check the following:
I10A fuse in fuse box
I75A fusible link in fusible
link box
IHarness continuity
between ECM relay and
battery positive supply
IHarness for open or
short-circuit between
ECM relay and accelera-
tor position switch.
If NG, repair harness or
connectors.
CHECK GROUND CIRCUIT.
1. Turn ignition switch to ªLOCKº position.
2. Disconnect ECM harness connector.
3. Check harness continuity between
accelerator work unit connector termi-
nalq
1and ECM connector terminal
426. Refer to wiring diagram.
Continuity should exist.
If OK; check harness for short-circuit.
If OK, re-connect harness connectors.
OK
ENG
Repair harness or connec-
tors.
CHECK COMPONENT.
(Accelerator position switch.)
Refer to ªCOMPONENT INSPECTIONº on
page EC-371.
OK
ENG
Replace accelerator pedal.
Disconnect and reconnect harness con-
nectors in the circuits. Then retest.
Trouble is not fixed
Check ECM pin terminals for damage and
check the connection of ECM harness
connector. Reconnect ECM harness con-
nector and retest.
