Function Inspection
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Display the PID IAT2. (See ON-BOARD DIAGNOSTIC TEST .) (See PCM INSPECTION .)
- Compare the voltage and temperature indications for the PID IAT2 with the standard in the table indicated below.
- If they do not match the standard, replace the PCM. (See PCM REMOVAL/INSTALLATION .)
- If they match the standard, perform the resistance inspection. (See RESISTANCE INSPECTION .)
