Test L: The Power Liftgate Module Does Not Communicate With The Scan Tool
PINPOINT TEST L: THE POWER LIFTGATE MODULE DOES NOT COMMUNICATE WITH THE SCAN TOOL
Normal Operation
The power liftgate module communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits VDB06 (GY/OG)
(MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the power liftgate module. The power liftgate module shares the
MS-CAN network with the smart junction box (SJB), the audio unit, the electronic automatic temperature control (EATC) or electronic manual
temperature control (EMTC) module, the driver seat module (DSM), the digital versatile disc (DVD) player, the satellite radio receiver and the
instrument cluster. Voltage for the power liftgate module is provided by circuits SBB29 (GY/RD) and SBP14 (BN/RD). Ground is provided by circuit
GD147 (BK/VT).
This pinpoint test is intended to diagnose the following:
-
