2. CHECK HARNESS
1. Turn ignition switch OFF.
2. Disconnect display unit connector and unified meter and A/C amp. connector.
3. Check continuity between display unit harness connector M62 terminal 7 (R/G) and unified meter and A/C amp. harness con-
nector M56 terminal 26 (R/G).
4. Check continuity between display unit harness connector M62 terminal 7 (R/G) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK VEHICLE SPEED SIGNAL
1. Connect unified meter and A/C amp. connector.
2. Drive vehicle at a constant speed.
3. Check the signal between display unit harness connector M62 terminal 7 (R/G) and ground with CONSULT-II or oscilloscope.
OK or NG
OK >> Replace display unit.
NG >> Check unified meter and A/C amp. system. Refer to DI-20, "
Vehicle Speed Signal Inspection" .
