POSSIBLE CAUSE
-
IPDM E/R
-
Sub starter & generator
-
CAN communication circuit
-
Harness or connectors (12V battery voltage circuits is open or short circuit)
FAIL-SAFE
Inhibit the idle start/stop system
DTC CONFIRMATION PROCEDURE
PERFORM DTC CONFIRMATION PROCEDURE
CONSULT
-
Start the engine and let it idle and wait for 1 second or more.
-
Select “Self diagnosis result” mode of “Sub starter & generator”.
Is DTC detected?
YES>>Refer to Diagnosis Procedure.
NO-1>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO-2>>Confirmation after repair: Inspection End.
Diagnosis Procedure
CHECK 12V BATTERY VOLTAGE
-
Ignition switch OFF.
-
Check the voltage between the 12V battery positive terminal and 12V battery negative terminal.
>>
GO TO 2.
CHECK FUSIBLE
-
Ignition switch OFF.
-
Check that the following fusible link is not blown (open):
Signal name Fusible No. Capacity 12V battery voltage 99 10 A
Is the fusible lnk blown (open)?
YES>>Replace the blown (open) fuse after repairing the affected circuit if a fuse is blown (open).
NO>>GO TO 3.
CHECK 12V BATTERY VOLTAGE SIGNAL
-
Disconnect sub starter & generator connector.
-
Check the voltage between the sub starter & generator harness connector and ground.
(+) (-) Voltage
(Approx.)Sub starter & generator Connector Terminal F126 3 Ground Battery voltage -
Check the continuity between the sub starter & generator harness connector and ground.
(+) (-) Continuity Sub starter & generator Connector Terminal F126 5 Ground Yes
Is the difference between the voltage value assumed in step 2 and the voltage value measured in step 4, 0.8 V or more?
YES>>Check power supply circuit.
NO>>GO TO 4.
CHECK 12V BATTERY VOLTAGE
CONSULT
-
Ignition switch ON.
-
Select “BATTERY VOLTAGE” of “IPDM E/R” data monitor item.
-
Check the value of “BATTERY VOLTAGE”.
Monitor item Value BATTERY VOLTAGE 11 – 14 V
Is the difference between the voltage value assumed in step 2 and the voltage value measured in step 5, 0.8 V or more?
YES>>GO TO 5.
NO>>Replace sub starter & generator. Refer to Removal and Installation.
CHECK POWER SUPPLY AND GROUND CIRCUIT OF IPDM E/R
Check power supply and ground circuit of IPDM E/R. Refer to Diagnosis Procedure
Is the inspection result normal?
YES>>Check intermittent incident. Refer to Intermittent Incident.
NO>>Replace IPDM E/R. Refer to Removal and Installation.
