CONDITIONS
DETAILS/RESULTS/ACTIONS
B13: CHECK THE CIRCUIT 14S-FA90 (VT/BK) FOR OPEN
1.
2 Measure the resistance between heater and
A/C control assembly, connector C329, pin 1,
circuit 14S-FA90 (VT/BK), harness side and
relay socket – A/C switch, connector C19, pin
2, circuit 14S-FA90 (VT/BK).
• Is the resistance less than 2 ohms?
Yes
CHECK the heater and A/C control
assembly. If necessary INSTALL a new one.
TEST the system for normal operation.
No
REPAIR the open circuit(s) between heater
and A/C control assembly and relay – A/C
switch by using the wiring diagrams. TEST
the system for normal operation.

1.
2 Turn the heater blower to the LOW SPEED
position.
3 Measure the resistance between relay socket –
A/C switch, connector C19, pin 1, circuit 31S-
FA90 (BK/GN) and ground.
• Is the resistance less than 2 ohms?
Yes
GO TO B15
No
REPAIR the open circuit(s) between relay –
A/C switch and ground by using the wiring
diagrams. TEST the system for normal op-
eration.
