PINPOINT TEST G: THE DRIVER DOOR MODULE (DDM) DOES NOT RESPOND TO THE SCAN TOOL

G1-G2:

G3-G4:

Normal Operation
The DDM communicates with the scan tool through the standard corporate protocol (SCP) communication network. Circuits 914 (TN/OG) (SCP +) and 915 (PK/LB) (SCP-) provide the network connection to the DDM. The DDM shares the SCP network with the lighting control module (LCM), the electronic automatic temperature control (EATC) module (if equipped) and the overhead console (if equipped). Voltage for the DDM is provided by circuit 1523 (DG). Circuit 676 (PK/OG) provides ground.

Possible Causes
- Fuse
- Circuit 676 (PK/OG) open
- Circuit 914 (TN/OG) open (SCP +)
- Circuit 915 (PK/LB) open (SCP -)
- Circuit 1523 (DG) open
- DDM
