Diagnostic Procedure 1EIS0093Y
Self-diagnostic results:
“CHAIN OF ECM-IMMU” displayed 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-18, "
CAN Com-
munication Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CONFIRM SELF-DIAGNOSTIC RESULTS
Confirm SELF-DIAGNOSTIC RESULTS “CHAIN OF ECM-IMMU”
displayed on CONSULT-II screen.
NOTE:
In rare case, “CHAIN OF ECM-IMMU” might be stored during key
registration procedure, even if the system is not malfunctioning.
Is CONSULT-II screen displayed as shown in figure?
Yes >> GO TO 2.
No >> GO TO BL-222, "
SYMPTOM MATRIX CHART 1" .
2. CHECK POWER SUPPLY CIRCUIT FOR BCM
1. Turn ignition switch OFF.
2. Check voltage between BCM and ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> Check the following.
40A fusible link (letter g , located in the fuse and fus-
ible link box).
10A fuse [No.8, located in the fuse block (J/B)].
Harness for open or short between fusible link and BCM.
Harness for open or short between fuse and BCM.
3. CHECK IGNITION SWITCH ON SIGNAL
1. Turn ignition switch ON.
2. Check voltage between BCM connector and ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 4.
NG >> Check the following.
10A fuse [No. 6, located in the fuse block (J/B)].
Harness for open or short between fuse and BCM.
