Checking For an Open Circuit
Figure 1:
DIODE - MAIN WIRING HARNESS - CHECKING FOR AN OPEN CIRCUIT
If the seat belt warning buzzer fails to operate, the cause may be an open circuit diode (C2000), Figure
1. Additionally, for turbo only, diodes (C262 & C263) may also be damaged. Diode locations are shown below.
^ Diode (C2000) - is located on the main wiring harness, above the fuse panel on the left side of the the instrument panel, Figure 1.
^ Diodes (C262 & C263 - Turbo Engines Only) - are located under the center console, on the RH side of the ECC processor.
