Pinpoint Test I: The Delayed Accessory Does Not Turn Off

Normal Operation

The accessory delay relay is located in the Smart Junction Box (SJB), and the relay coil receives battery voltage through circuit 294 (WH/LB) at all times. When the key is turned ON, the SJB activates the accessory delay relay by grounding the relay coil, and power is sent to all window control switches. When the key is turned OFF, the SJB continues to ground the accessory delay relay coil for approximately 10 minutes, or until a door is opened.

- DTC B1475 Accessory Delay Relay Short to Battery - Output circuit shorted to battery or relay contacts stuck closed.

This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Accessory delay relay
- Wiring, terminals or connectors
- SJB



PINPOINT TEST I: THE DELAYED ACCESSORY DOES NOT TURN OFF

-------------------------------------------------
I1 CHECK FOR CORRECT OPERATION OF THE DOOR AJAR SWITCHES


- Open and close and LH and RH doors and verify the interior lights turn ON when the doors are open, and OFF when the doors are closed. Carry out the Accessory Delay Relay Component Test.

- Do the interior lights operate correctly?

Yes
GO to I2.

No
REFER to Courtesy Lamp to diagnose the interior light concern. Testing and Inspection

-------------------------------------------------
I2 CHECK THE ACCESSORY DELAY RELAY


- Disconnect: Accessory Delay Relay.
- Carry out the Accessory Delay Relay Component Test.

- Is the accessory delay relay OK?

Yes
GO to I3.

No
INSTALL a new accessory delay relay. TEST the system for normal operation.

-------------------------------------------------
I3 CHECK FOR SHORT TO VOLTAGE AT ACCESSORY DELAY RELAY OUTPUT


- Measure the voltage between accessory delay relay pin 87, harness side and ground.




- Is any voltage present?

Yes
GO to I4.

No
GO to I5.

-------------------------------------------------
I4 CHECK FOR SHORT TO VOLTAGE


- Measure the voltage between SJB and ground. Refer to the following table:
- Disconnect SJB C2280A, C2280E and C2280G.





- Is any voltage present?

Yes
REPAIR the circuit in question. TEST the system for normal operation.

No
GO to I5.

-------------------------------------------------
I5 CHECK FOR CORRECT SJB OPERATION


- Disconnect all SJB connectors.
- Check for:
- corrosion.
- pushed-out pins.
- Connect all SJB connectors and verify the concern is still present?
- Is the concern still present?

Yes
INSTALL a new SJB. TEST the system for normal operation.

No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
