(5) Measure the resistance between joint connector (3)
terminal 6 and A/C-ECU connector terminal 5 <manual air

system (middle) or automatic air conditioning system>.
OK: 2 ohms or less
CAUTION
Strictly observe the specified wiring harness repair proce-
dure. For details refer to
Q: Do all the resistances measure 2 ohms or less?
YES : If all the resistances measure 2 ohms or less, power
supply to the A/C-ECU may be suspected. Diagnose
the air conditioning system. Refer to GROUP 55A,
Manual A/C diagnosis
NO : If either of the resistances measures more than 2
ohms or all the resistances measure more than 2
ohms, repair the wiring harness between joint
connector (3) and the A/C-ECU connector.
