DTC Diagnosis Procedure

CHECK STARTER CUT RELAY INPUT SIGNAL

Check voltage between BCM harness connector and ground.

(+) (-) Condition

Voltage

(Approx.)
BCM
Connector Terminal
E29 (with type B meter 123 Ground Other than following Battery voltage
E60 (with type A meter 124 At engine cranking 0 V

Is the inspection result normal?

YES>>

GO TO 4.

NO>>

GO TO 2.

CHECK STARTER CUT RELAY INPUT SIGNAL CIRCUIT

  1. Ignition switch OFF.

  2. Disconnect BCM connector and starter cut relay connector.

  3. Check continuity between BCM harness connector and starter cut relay harness connector.

    BCM Starter cut relay Continuity
    Connector Terminal Connector Terminal
    E29 (with type B meter) 123 F55 9 Yes
    E60 (with type A meter) 124

  4. Check continuity between BCM harness connector and ground.

    BCM — Continuity
    Connector Terminal
    E29 (with type B meter) 123 Ground No
    E60 (with type A meter) 124

Is the inspection result normal?

YES>>

GO TO 3.

NO>>

Repair or replace harness.

CHECK FUSIBLE LINK

Check that the following fusible link is not blown (open).

Signal name Fusible link
Battery power supply Y (30 A)

Is the fusible link blown (open)?

YES>>

Replace the blown (open) fusible link after repairing the affected circuit if a fusible link is blown (open).

NO>>

GO TO 6.

CHECK STARTER CUT RELAY OUTPUT SIGNAL

Check voltage between IPDM E/R harness connector and ground.

(+) (-) Condition

Voltage

(Approx.)
IPDM E/R
Connector Terminal
F41 86 Ground Other than at engine cranking Less than 4 V (IPDM E/R always outputs the voltage to detect the ON/ OFF state of starter cut relay)
At engine cranking 6 - 16 V

Is the inspection result normal?

YES>>

Inspection End.

NO>>

GO TO 5.

CHECK STARTER CUT RELAY OUTPUT SIGNAL CIRCUIT

  1. Ignition switch OFF.

  2. Disconnect IPDM E/R connector and starter cut relay connector.

  3. Check continuity between IPDM E/R harness connector and starter cut relay harness connector.

    IPDM E/R Starter cut relay Continuity
    Connector Terminal Connector Terminal
    F41 86 F55 7 Yes

  4. Check continuity between IPDM E/R harness connector and ground.

    IPDM E/R — Continuity
    Connector Terminal
    F41 86 Ground No

Is the inspection result normal?

YES>>

GO TO 6.

NO>>

Repair or replace harness.

CHECK STARTER CUT RELAY

Check starter cut relay. Refer to Component Inspection.

Is the inspection result normal?

YES>>

Inspection End.

NO>>

Replace starter cut relay.
