DIAGNOSIS
Required Special Tools:
• MB991223: Harness Set
STEP 1. Check joint connector (9) D-131.
CAUTION
If there is a problem in the connector(s) (including termi-
nals) or wire(s) of the instrument panel wiring harness
assembly (the wiring harness connected to the steering
wheel sensor, the data link connector and the resistor) and
the transmission wiring harness assembly (the wiring har-
ness connected to the G and yaw rate sensor connector
and intermediate connector E-123), cut and repair the
defective wire so that the frayed end of the twisted wire
should be within 10 cm (4.0 inches). If it exceeds 10 cm (4.0
inches), twist the wiring harness just like the original
twisted wire. If the frayed end exceeds 10 cm (4.0 inches),
a communication error may be caused.
Q: Is joint connector D-131 in good condition?
YES : Go to Step 2.
NO : Repair or replace the connector(s).
