Removal 1. Remove the negative (-) battery terminal. 2. Remove the driver seat in the car. (Refer to Body - "Front Seat") 3. Remove the IMS module (A) after loosening 3 screws in the bottom of seat.
Inspection 1. Disconnect the IMS control switch connector. 2. With the power IMS control switch in each position, make sure that continuity exists between the terminals below.
Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
Inspection 1. Ignition "OFF". 2. Disconnect evaporator temperature sensor. 3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor. Specification Evaporator coretemperature [°C(°F)]Resistance[KΩ]Voltage[V]-20(-4)70.
