3. Gain access to Blue 56-pin in-
line harness connector, located under floor console trim plate. Turn ignition
switch to RUN position, then to OFF position (RAP mode). Ensure doors stay closed so as not to exit
RAP mode. Using DVOM connected to ground, backprobe Blue 56-pin in-line harness connector
terminal B9 (Dark Blue wire). See Fig. 4
. If battery voltage exists, go to next step. If battery voltage does
not exist, go to step 5 .
4.
Using DVOM connected to ground, backprobe RR WIPER fuse located in instrument panel fuse block. If
battery voltage exists, system is okay at this time. If battery voltage does not exist, go to step 7 .
5. Using DVOM connected to ground, backprobe Black 6-pin BCM connector C2 terminal "C" (Dark Blue
wire). If battery voltage exists, go to next step. If battery voltage does not exist, go to step 8 .
6. Repair open in Dark Blue wire between Black 6-pin BCM connector C2 terminal "C" and Blue 56-pin in-
line harness connector terminal B9. See WIRING DIAGRAMS . Retest operation.
7. Repair open in Dark Blue wire between Blue 56-pin in-line harness connector terminal B9 and CTSY
fuse. See WIRING DIAGRAMS . Retest operation.

1. Gain access to Blue 56-pin in-line harness connector, located under floor console trim plate. Disconnect
Blue 56-pin in-line harness connector. Using DVOM connected to ground, backprobe console-side of
Blue 56-pin in-line harness connector terminal B9. See Fig. 4
. If battery voltage exists, go to next step. If
battery voltage does not exist, go to step 3 .
2. Check for short to voltage in Dark Blue wire between Black 6-pin BCM connector C2 terminal "C" and
Blue 56-pin in-line harness connector terminal B9. See Fig. 3 . See WIRING DIAGRAMS . Repair as
necessary and retest operation. If Dark Blue wire checks okay, go to step 5 .
3. Using DVOM connected to ground, backprobe instrument panel-side of Blue 56-pin in-line harness
connector terminal B9. If battery voltage exists, go to next step. If battery voltage does not exist, system
is okay at this time.
4. Repair short to battery voltage in Dark Blue wire between Blue 56-pin in-line harness connector terminal
B9 and instrument panel fuse block. See WIRING DIAGRAMS . Retest operation.
5. Replace Body Control Module (BCM). See BODY CONTROL MODULE (BCM) under REMOVAL
