Reassembly
1. INSTALL REAR DRIVE SHAFT OUTBOARD JOINT BOOT
HINT:
Before install the boot, wrap the spline of the outboard
joint shaft with vinyl tape to prevent the boot from
bearing damaged.
(a) Install new outboard joint boot, 2 outboard joint boot
clamps, 2 inboard joint boot clamps and inboard
j ...
Data list / active test
1. DATA LIST
HINT:
Reading the DATA LIST displayed on an intelligent tester
enables values, including those of the switches, sensors,
and actuators, to be checked without removing any
parts. Reading the DATA LIST as the first step in
troubleshooting is one method to shorten diagnostic
time.
