Control System JL4G18-D
(a) Turn the ignition switch to "OFF" position.
(b) Remove IF12 from the I/P fuse block.
(c) Use multimeter to measure whether there is conduction
between the two terminals.
Conducted?
Check whether there are short circuits.
No
Replace the fuses.
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect ECM harness connector EN01.
(c) Turn the ignition switch to "ON" position.
(d) Measure voltage between ECM harness connector EN01
terminal No.16 and a reliable ground.
(e) Measure voltage between ECM harness connector EN01
terminal No.17 and a reliable ground.
Standard Voltage: 11-14 V
Voltage normal?
Go to step 5
No
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect ECM harness connector EN01.
(c) Measure resistance between ECM harness connector EN01
terminal No.5 and a reliable ground.
(d) Measure resistance between ECM harness connector EN01
terminal No.43 and a reliable ground.
(e) Measure resistance between ECM harness connector EN01
terminal No.48 and a reliable ground.
Standard Resistance: Less than 1 Ω
Resistance normal?
ECM ground circuit is faulty. Repair the faulty
No
