ness for open or
short between
stop light/brake
switch and fuse &
relay box.
 Check the clutch
switch and circuit.
3 CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Disconnect the ECM harness connector.
3) Measure the resistance between ECM har-
ness connector terminal and stop light switch
and brake switch harness connector terminal.
Connector & terminal
(B136) No. 8 — (B65) No. 3:
(B136) No. 9 — (B65) No. 4: Is the resistance less than 10
Ω? Go to step 4.Repair the har-
ness.
4 CHECK STOP LIGHT SWITCH AND BRAKE
SWITCH.
Remove and check the stop light switch and
brake switch. Switch.>Are the stop light switch and
brake switch OK? Stop light switch
and brake switch
circuit are OK.Replace the stop
light switch and
brake switch.
