1. Turn the ignition switch ON (II), and watch the D4
indicator.
Does the D4 indicator come on and stay on?
YES Go to step 2.
NO If the light comes on for about 2 seconds and
then goes off, it's OK. If it doesn't come on at all, go
to step 12.
2. Make sure the HDS is not connected to the Data
Link Connector (DLC).
3. Turn the ignition switch OFF.
4. Disconnect the A (32P) and D (16P) connectors from
the PCM.
5. Turn the ignition switch ON (II).

between the D9 terminal and the transmission
range switch. If the wire is OK, check the
transmission range switch.

known-good PCM and recheck. If the light then
works OK every time, replace the original PCM.
