General Inspection After or before servicing the EPS system, perform the troubleshooting and test procedure as follows. Compare the system condition with normal condition in the table below and if abnormal symptom is detected, perform necessary remedy and inspection.
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. Be sure to use oil specified for the model of compressor.
Inspection 1. Measure terminal - to - terminal resistance of blower resistor. 2. If measure resistance isnot within specification, the blower resistor must be replaced. Replacement 1. Disconnect the negative (-) battery terminal. 2. Remove the crash pad lower cover (A) and then disconnect the connector (B).
