Dtc "C24" (P0351) Or "C25" (P0352): Ignition System Malfunction - Suzuki GW250 Service Manual

Step 4
TO sensor check
1) Turn the ignition switch OFF.
2) Connect the ECM couplers and TO sensor coupler.
3) Insert the needle-point probes to the lead wire coupler.
4) Turn the ignition switch ON.
5) Measure the TO sensor voltage between the Br wire and B/Br
wire.
 09900-25008: Multi circuit tester set
09900-25009: Needle-point probe set
 Tester knob indication: Voltage ()
 TO sensor voltage (Normal):
0.4 – 1.4 V
(+ terminal: Br – - terminal: B/Br)
6) Measure the voltage when it is leaned 65° and more, left and
right, from the horizontal level.
 09900-25008: Multi circuit tester set
09900-25009: Needle-point probe set
 Tester knob indication: Voltage ()
 TO sensor voltage (Leaning):
3.7 – 4.4 V
(+ terminal: Br – - terminal: B/Br)
Is check result OK?
Replace the ECM with a known good one, and
YES
inspect it again.
NO Replace the TO sensor with a new one.
7) Install the TO sensor. (4-92)
