Checking the power supply (IG1) and ground (Honda Accord 3)

Check for electrical continuity between ground and Black terminal 32.

If there is no electrical connection, then the break in the Black wire between point G2 and terminal 32 of the control unit should be repaired.

If there is an electrical connection, then the ignition should be turned on.

Next, measure the voltage between Black/Yellow (+) 23 and Black (-) 32 pins.

If there is battery voltage, then the IG1 power source and ground are normal.

If there is no voltage, then you should check fuse No.1 (15 A).

If the fuse is normal, then you should repair the break in the Black/Yellow wire between fuse #1 and terminal 23 of the control unit.

If the fuse is blown, it should be replaced.
