Diagnostics Procedure with Diagnostic Trouble Code (DTC)
Step
Check
Yes
No
1
CHECK POWER SUPPLY CIRCUIT OF IMM
ECM.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from
IMM ECM.
3) Measure the voltage between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 10, No. 11 (+) — Chassis
ground(
−
):
Is the voltage more than 10 V? Go to step
Check the harness
for open or short
between IMM
ECM and fuse.
2
CHECK IGNITION SWITCH CIRCUIT.
1) Turn the ignition switch to ON. (engine
OFF.)
2) Measure the voltage between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 12 (+) — Chassis ground(
−
):
Is the voltage more than 10 V? Go to step
Check the harness
for open or short
between IMM
ECM and ignition
switch.
3
CHECK GROUND CIRCUIT OF IMM ECM.
1) Turn the ignition switch to OFF.
2) Measure the resistance between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 2, No. 3 — Chassis ground:
Is the resistance less than 10
Ω
?
Repair the open
circuit of IMMECM
ground circuit.
4
CHECK HARNESS BETWEEN IMM ECM
AND ECM.
1) Disconnect the harness connector from
ECM and IMM ECM.
2) Measure the resistance between IMM ECM
harness connector terminal and ECM harness
connector terminal.
