Pinpoint Test L: The Global Open/Closing Function is Inoperative

Normal Operation

When the Smart Junction Box (SJB) receives the correct input from the Remote Keyless Entry (RKE), the SJB (Smart Junction Box) will send a signal on circuit CPW01 (BN/BU) to operate the roof opening panel motor to the VENT position (if equipped) and activate a one-touch up or one-touch down operation of both front and rear door windows. The global open/close feature does not operate if the accessory delay relay is active.

- DTC B2947 (Global Opening/Closing Circuit Open)- Sets when the SJB (Smart Junction Box) detects an open or short to ground in the global open circuit.

- DTC B2949 (Global Opening/Closing Circuit Short to Battery)- Sets when the SJB (Smart Junction Box) detects a short to voltage in the global open circuit.

This pinpoint test is intended to diagnose the following:

- Window regulator motor not initialized

- Wiring, terminals or connections

- Window regulator motor

- RKE (Remote Keyless Entry) transmitter

- SJB (Smart Junction Box)

PINPOINT TEST L : THE GLOBAL OPEN/CLOSING FUNCTION IS INOPERATIVE

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: One-touch up/down must be activated from the message center for the global open function to operate correctly. Make sure one-touch up/down is activated before proceeding with this diagnostic.
