Report a problem with this article2004 - RX8 - Workshop Manual - EnginePCM INSPECTIONNot Using the WDS or Equivalent
NOTE:
The PCM terminal voltage can vary with conditions when measuring and changes due toage deterioration on the vehicle, causing false diagnosis. Therefore a comprehensiveinspection of the input and output systems, and the PCM is necessary to determine wherethe malfunction occurs.

Using the WDS or Equivalent
NOTE:
PIDs for the following parts are not available on this model. Go to the appropriate partinspection page.
Main relay (See RELAY INSPECTION.)
1. Connect the WDS or equivalent to the DLC-2.
2. Turn the ignition switch to ON position.
3. Measure the PID value.
If PID value is not within the specification, follow the instructions in Actioncolumn.
NOTE:
The PID/DATA MONITOR function monitors the calculated value of theinput/output signals in the PCM. Therefore, an output device malfunction is notdirectly indicated as a malfunction of the monitored value for the output device. Ifa monitored value of an output device is out of specification, inspect themonitored value of the input device related to the output control.
For input/output signals except those of the monitoring items, use a voltmeter tomeasure the PCM terminal voltage.
The simulation items that are used in the ENGINE CONTROL SYSTEMOPERATION INSPECTION are as follows.
ACCS, AIP RLY, ALTF, APV, ARPMDES, DEI, ETC_DSD,EVAPCP, FAN1, FAN2, FP, FPRR, FUELPW, GENVDSD,HTR11, HTR12, IASV, MOP POS, PACNTV, SSV, test
