Nissan Rogue (T33) 2021-Present Service Manual / Electrical & Power Control :: Power Control System / Ipdm E/r :: Dtc/circuit Diagnosis / B20dd-73 Ign Relay on Circ

DTC Description

  • IPDM E/R operates the ignition relay when it receives an ignition ON signal from BCM via CAN communication.

  • Turn the ignition relay OFF by pressing the push-button ignition switch once when the Nissan Ariya vehicle speed is 2.5 MPH (4 km/h) or less.

  • Turn the ignition relay OFF with the following operation when the Nissan Ariya vehicle speed is more than 2.5 MPH (4 km/h) or when an abnormal condition occurs in CAN communication from the ABS actuator and electric unit (control unit) (emergency OFF):

    • Press and hold the push-button ignition switch for 2 seconds or more.

    • Press the push-button ignition switch 3 times within 1.5 seconds.

NOTE:

The ignition relay does not turn ON for 3 seconds after emergency OFF even if the push-button ignition switch is pressed.

DTC Diagnosis Procedure

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 1

CONSULT

  1. Ignition switch ON

  2. Select “Self diagnosis result” mode of “IPDM E/R”.

  3. Remove fuse [No. 74 (10A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 74 (10A)] downstream of the ignition relay in the IPDM E/R.

NO>>

GO TO 2.

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 2

CONSULT

  1. Return fuse [No. 74 (10A)] downstream of the ignition relay in the IPDM E/R back to the original position.

  2. Remove fuse [No. 73 (10A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 73 (10A)] downstream of the ignition relay in the IPDM E/R.

NO>>

GO TO 3.

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 3

CONSULT

  1. Return fuse [No. 73 (10A)] downstream of the ignition relay in the IPDM E/R back to the original position.

  2. Remove fuse [No. 76 (5A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 76 (5A)] downstream of the ignition relay in the IPDM E/R.

NO>>

GO TO 4.

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 4

CONSULT

  1. Return fuse [No. 76 (5A)] downstream of the ignition relay in the IPDM E/R back to the original position.

  2. Remove fuse [No. 71 (10A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 71 (10A)] downstream of the ignition relay in the IPDM E/R.

NO>>

GO TO 5.

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 5

CONSULT

  1. Return fuse [No. 71 (10A)] downstream of the ignition relay in the IPDM E/R back to the original position.

  2. Remove fuse [No. 81 (15A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 81 (15A)] downstream of the ignition relay in the IPDM E/R.

NO>>

GO TO 6.

CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 6

CONSULT

  1. Return fuse [No. 81 (15A)] downstream of the ignition relay in the IPDM E/R back to the original position.

  2. Remove fuse [No. 85 (20A)] downstream of the ignition relay in the IPDM E/R, and check the change in “Self diagnosis result”.

Is it now a past malfunction?

YES>>

Perform an inspection of the downstream circuit of fuse [No. 85 (20A)] downstream of the ignition relay in the IPDM E/R.

NO>>

Replace IPDM E/R. Refer to Removal and Installation.
