DIAGNOSTIC PROCEDURE 6
(NATS release signal check)
Does engine start properly?
Ye s
cNo
Check NATS system.
CHECK NATS SIGNAL CIRCUIT.
1. Disconnect control unit connector and
NATS IMMU connector.
2. Check continuity between control unit
terminalj
9and NATS IMMU terminal
j
3(LHD models),j7(RHD models).
Continuity should exist.
3. Check continuity between control unit
terminalj
9and ground.
Continuity should not exist.
Refer to wiring diagram in EL-215
(LHD), EL-219 (RHD).
OK
cNG
Repair harness.
CHECK NATS RELEASE SIGNAL.
1. Connect control unit connector and
NATS IMMU connector.
2. Check voltage between control unit ter-
minalj
9and ground.
OK
cNG
Check NATS system.
Replace super lock control unit.
