7. Check continuity between
transmission ECU connector
pin 41 and connector X173 pin
6 and between transmission
ECU connector pin 3 and
connector X173 pin 5.
a. If continuity is not present,
repair or replace connectors
(WP 0111 00).
b. If wiring harness must be
replaced, notify SRA.
8. Disconnect
transmission
turbine
speed
sensor
connector 751 and perform
internal resistance check of
engine
speed
sensor.
Resistance should be 1050 +/-
100 ohms.
If resistance is not as specified,
replace turbine speed sensor (WP
0095 00).
