POWER INPUT LINE
Measure the voltage between the wire harness side
ECM/PCM 33P (Black) connector [1] and ground. [1]
TOOL:
Test probe 07ZAJ-RDJA110

CONNECTION: B1 (+) – Ground (–)
There should be battery voltage with the ignition switch B1
turned ON and engine stop switch " ".
If there is no voltage, check the following:
– Open circuit in the Black/white wire between the
ECM/PCM and main relay
– FI relay (page 4-43) and related circuit

GROUND LINE
Check for continuity between the wire harness side
ECM/PCM 33P (Black) connector [1] and ground. [1]
TOOL:
Test probe 07ZAJ-RDJA110
CONNECTION: B11 – Ground B22 B33 B11 B12
B12 – Ground
B22 – Ground
B33 – Ground (CRF1000D)
There should be continuity at all times.
