DTC P0384:00

Glow control module circuit high input

DETECTION CONDITION
•  The PCM monitors the input current from the glow control module. If the input current is above 5.9 A for 5 s, the PCM determines that the glow control module circuit has a malfunction.
MONITORING CONDITIONS
―  Battery voltage: 9—16 V
―  0.5 s have elapsed after the ignition was switched ON
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE
•  Glow control module connector or terminals malfunction
•  Open circuit in wiring harness between glow control module terminal 2A and body ground
―  GLOW SIG 5 A fuse malfunction
•  PCM connector or terminals malfunction
•  Short to power supply in wiring harness between the following terminals:
―  Glow control module terminal 2B—PCM terminal 2I
―  Glow control module terminal 2E—PCM terminal 2BA
•  Open circuit in wiring harness between the following terminals:
―  Glow control module terminal 2B—PCM terminal 2I
―  Glow control module terminal 2E—PCM terminal 2BA
•  Glow control module malfunction
•  PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT GLOW CONTROL MODULE CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the glow control module connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 9.
No
Go to the next step.
4
INSPECT GLOW CONTROL MODULE GROUND CIRCUIT FOR OPEN CIRCUIT
•  Verify that the glow control module connector is disconnected.
•  Inspect for continuity between glow control module terminal 2A (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Inspect the GLOW SIG 5 A fuse.
•  If the fuse is blown or deteriorated:
―  Replace the fuse.
•  If the fuse is normal:
―  Refer to the wiring diagram and verify whether or not there is a common connector between glow control module terminal 2A and body ground.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 9.
5
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 9.
No
Go to the next step.
6
INSPECT GLOW CONTROL MODULE CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the glow control module and PCM connectors are disconnected.
•  Switch the ignition ON (engine off).
•  Measure the voltage at the following terminals (wiring harness-side):
―  Glow control module terminal 2B
―  Glow control module terminal 2E
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  Glow control module terminal 2B—PCM terminal 2I
•  Glow control module terminal 2E—PCM terminal 2BA
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to power supply.
Go to Step 9.
7
INSPECT GLOW CONTROL MODULE CIRCUIT FOR OPEN CIRCUIT
•  Verify that the glow control module and PCM connectors are disconnected.
•  Switch the ignition off.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Glow control module terminal 2B—PCM terminal 2I
―  Glow control module terminal 2E—PCM terminal 2BA
•  Is there continuity?
Yes
Go to the next step.
No
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  Glow control module terminal 2B—PCM terminal 2I
•  Glow control module terminal 2E—PCM terminal 2BA
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has an open circuit.
Go to Step 9.
8
INSPECT GLOW CONTROL MODULE
•  Inspect the glow control module.
•  Is there any malfunction?
Yes
Replace the glow control module, then go to the next step.
No
Go to the next step.
9
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the DTC Reading Procedure.
•  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.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
