If +24 VDC is not present on either wire, repair wiring 223
between brake indicator light (in instrument cluster panel light)
if +24 VDC is present on both wires, reconnect wire 223 and
wire 224 and go to step 3.
Step 3. Disconnect wire 018 (4) and wire 019 (5) at reservoirs (3) and check for
continuity to ground.
If wire 018 is short to ground but wire 019 is not, repair
wiring 019 between reservoirs.
If both wires are open to ground, repair wiring 018 between
reservoir and ground.
If both wires are short to ground, reconnect wire 018 and
wire 019 and go to step 4.
Step 4. Disconnect wire 223 (1), wire 224 (2), wire 018 (4), and wire 019 (5) at
Step 5. Remove filler opening caps (6 and 7) and check continuity between
