Diagnostic Procedure 1BIS000YN
Self-diagnostic results:
“CHAIN OF ECM-IMMU” display on CONSULT-II screen
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, then perform the trouble diagno-
sis of malfunction system indicated “SELF-DIAG RESULTS” of “BCM”. Refer to BCS-14, "
CAN Com-
munication Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CHECK SELF-DIAGNOSTIC RESULTS
Check SELF-DIAGNOSTIC RESULTS “CHAIN OF ECM-IMMU” dis-
played on the screen?
Is CONSULT-II screen displayed as above?
YES >> GO TO 2.
NO >> GO TO BL-152, "
Trouble Diagnosis Symptom Chart" .
2. CHECK POWER SUPPLY CIRCUIT FOR BCM
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM connector M4 terminal 42 (Y/R),
55 (W/B) and ground.
OK or NG
OK >> GO TO 3.
NG >> Check the following.

50A fusible link [Letter M , located in fuse block (J/B)]

15A fuse [No.17, located in fuse block (J/B)]

Harness for open or short between fusible link or fuse
and BCM.
3. CHECK IGNITION SWITCH ON SIGNAL
1. Turn ignition switch ON.
2. Check voltage between BCM connector M3 terminal 38 (R) and
ground.
OK or NG
OK >> GO TO 4.
NG >> Check the following.

10A fuse [No.1, located in fuse block (J/B)]

Harness for open or short between fuse and BCM.

CAUTION:
Even when there is no malfunction on CAN communica-
tion system, malfunction may be misinterpreted when bat-
tery has low voltage (when maintaining 7-8V for about 2
seconds) or 10A fuse [No. 19, located in the fuse block (J/
B)] is disconnected.

HOW TO PROCEED WITH TROUBLE DIAGNOSIS
1. Confirm the malfunction symptom or customer complaint.
2. Understand the outline of system. Refer to DI-56, "
System Description" .
3. Perform preliminary check. Refer to DI-66, "
PRELIMINARY CHECK" .
4. Select “METER A/C AMP” on CONSULT-II, and then perform self-diagnosis of unified meter and A/C
amp. Refer to DI-29, "
CONSULT-II Function (METER A/C AMP)" . When no malfunction detected, go to
next step 5. When malfunction detected, go to DI-17, "
SYMPTOM CHART 2" in “COMBINATION
METER”.
5. Check symptom and repair or replace the cause of malfunction.
6. Does the warning chime operate normally? If so, GO TO 7. If not, GO TO 5.
7. INSPECTION END
PRELIMINARY CHECK
1. CHECK FUSE AND FUSIBLE LINK
Check BCM fuses and fusible link for blown-out.
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
