Specification Items Specification APS 1 APS 2 C.T 0.
Inspection 1. Connect the diagnostic tool on the Diagnosis Link Connector (DLC). 2. Start engine and check output voltages of APS 1 and 2 at C.
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Remove the heater unit assembly. (Refer to Heater - "Heater Unit") 3. Separate the evaporator temperature sensor connector (A), loosen the mounting screws and remove the eva
