Insert the tips into the upper side-slits (A in Rear View) and get the bottom side of the Shield. Push the tweezers down in the direction indicated by an arrow in Side View. 2 Now one of the 18-pin connectors gets disconnected from the DSP Unit by doing 1 so that it becomes easier to detach the DSP Unit. Lift and remove the DSP Unit and the Shield together. Be careful not to give any stress to the 18-pin connectors on both sides when removing the DSP Unit and the Shield.

Under the occurrence of the error, DSP IC will be required to execute the initialization command by the system microcomputer until DSP IC gets back to normal. However, the error cannot be fixed because of defective IC, and so the initialization will be commanded over and over again. While this condition prevails, follow the description below about observations of the IC101 waveforms to distinguish defective DSP IC. [Observations of the IC101 waveforms] • First, perform the 67 pin (drst) waveform observations. When DSP error occurs, this waveform repeats "Hi/Low" shapes after ACC ON. For reference sake, when there is no problem, the 67 pin (drst) waveform should keep "Hi" continuously after ACC ON. • Then, perform the 19 pin (DSPCHIP) waveform observations. While the 67 pin (drst) waveform stays at "Low", perform the 19 pin waveform observations and produce a decision. • The 19 pin (DSPCHIP) waveform during DSP error Keeping "Hi" continuously : IC301 is defective. Proper IC311 operation is not guaranteed, though. After making repairs on IC301, re-perform the 67 pin (drst) waveform observations. Keeping "Hi" continuously on the 67 pin (drst) waveform shows that DSP IC functions normally. Keeping "Low" continuously : IC311 is defective. IC301 is OK. After making repairs on IC311, re-perform the 67 pin (drst) waveform observations.
