INSPECT CURRENT SENSOR POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT
• Current sensor connector is disconnected.
• Measure the voltage at the current sensor terminal B (wiring harness-side).
• Is the voltage B+?
|
Yes
|
Go to the next step.
|
|
No
|
Inspect the MAIN 200 A fuse and HORN 10 A fuse.
• If the fuse is melted:
-
― Repair or replace the wiring harness for a possible short to ground.
― Replace the malfunctioning fuse.
• If the fuse is deteriorated:
-
― Replace the malfunctioning fuse.
• If all fuses are normal:
-
― Repair or replace the wiring harness for a possible open circuit.
Go to Step 9.

|
INSPECT CURRENT SENSOR CIRCUIT FOR SHORT TO GROUND
• Current sensor connector is disconnected.
• Inspect for continuity between current sensor terminal A (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
If the short to ground circuit could be detected:
• Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
• Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 9.
|
|
No
|
Go to the next step.

|
|
No
|
Go to the next step.
|
|
7
|
INSPECT CURRENT SENSOR CIRCUIT FOR OPEN CIRCUIT
• Current sensor and PCM connectors are disconnected.
• Inspect for continuity between current sensor terminal A (wiring harness-side) and PCM terminal 1AA (wiring harness-side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
|
|
8
|
INSPECT CURRENT SENSOR
• Reconnect all disconnected connectors.
• Inspect the current sensor.
• Is there any malfunction?
|
Yes

|
|
No
|
Go to the next step.
|
|
9
|
VERIFY DTC TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Perform the KOEO or KOER self test.
• Is the same DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
|
No
|
Go to the next step.
|
