Pinpoint Test H: The Puddle Lamps Stay On Continuously

Refer to Wiring Diagram Set 89, Interior Lamps for schematic and connector information. Diagrams By Number

Normal Operation

The Smart Junction Box (SJB) provides voltage to the puddle lamps.

- DTC B2A39 (Puddle Lamp Output Circuit Open) - an on-demand DTC that sets when the SJB detects a short to voltage on the puddle lamp output circuit.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- SJB


PINPOINT TEST H: THE PUDDLE LAMPS STAY ON CONTINUOUSLY

-------------------------------------------------
H1 CHECK THE EXTERIOR MIRROR INPUT CIRCUIT FOR A SHORT TO VOLTAGE


- Ignition OFF.
- Disconnect: SJB C2280c.
- Ignition ON.
- Do the puddle lamps continue to illuminate?

Yes
REPAIR circuit CLN25 (VT) for a short to voltage. CLEAR the DTCs. REPEAT the self-test.

No
GO to H2.

-------------------------------------------------
H2 CHECK FOR CORRECT SJB OPERATION


- Disconnect all the SJB connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins

- Connect all the SJB connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new SJB. REFER to Multifunction Electronic Modules Service and Repair. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
