Reception data check from BCM
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch.
3) Check DTC for reception data from BCM.
Is there DTC P1678?
Go to applicable DTC
diag. flow.
Go to Step 2.
2
A/C switch signal circuit check
1) Start engine and select “DATA LIST” mode on scan tool.
2) Check A/C switch signal under following conditions
respectively.
A/C switch signal
Engine running, A/C switch OFF: OFF
Engine running, A/C switch ON and blower speed
selector turned 1st position or more: ON
Is check result satisfactory?
Go to Step 3.
Check A/C switch
circuit.

Is there DTC P0116, DTC P0117 or DTC P0118?
Go to applicable DTC
diag. flow.
Go to Step 4.
4
Radiator cooling fan control system check
Is radiator cooling fan started when A/C and blower speed
selector switch are turned ON with engine running?
Go to Step 10.
Go to Step 5.
5
Radiator cooling fan control circuit check
1) Check DTC with scan tool.
Is DTC P0480 displayed?
Go to “DTC P0480: Fan
1 (Radiator Cooling
