2.PERFORM INITIALIZATION WITH CONSULT-III
Perform initialization with CONSULT-III. Re-register all NATS ignition key IDs.
For initialization, refer to “CONSULT-III Operation Manual NATS”.
NOTE:
If the initialization is not completed or ma lfunctions, CONSULT-III shows message on the screen.
Can the system be initialized?
Yes >> • Start engine. (END) • (System initialization had not been completed.)
No >> ECM is malfunctioning. • Replace ECM.
• Perform initialization with CONSULT-III
For initialization, refer to “CONSULT-III Operation Manual NATS”
Diagnosis Procedure 4INFOID:0000000005396714
“COMBINATION METER (SECURITY) DOES NOT LIGHT UP”
1.CHECK FUSE
Check 10A fuse [No.13, located in the fuse block (J/B)]
OK or NG
OK >> GO TO 2
NG >> Replace fuse.
2.CHECK COMBINATION METER (SECURITY)
1. Install 10A fuse.
2. Start engine and turn ignition switch OFF.
3. Check if the combination meter (security) lights up.
OK or NG
OK >> Inspection End.
NG >> GO TO 3
3.CHECK COMBINATION METER (SECURITY) POWER SUPPLY CIRCUIT
1. Disconnect combination meter (security) connector.
2. Check voltage between combination meter (security) connector and ground.
OK or NG
OK >> GO TO 4
NG >> Check harness for open or short between fuse and com- bination meter (security).
4.CHECK BCM FUNCTION
1. Connect combination meter (security) connector.
2. Disconnect BCM connector.
3. Check voltage between BCM connector and ground. Combination meter (security) should light up.
