Suzuki Burgman AN400, Service Manual

Page: 253 / 475

Ignition System: 1H-7
2) Disconnect the ECM coupler (1).
NOTE
Make sure that all of the couplers are
connected properly and the battery is fully-
charged.
3) Connect the multi-circuit tester with the peak volt
adaptor as follows.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
Tester knob indication: Voltage ( )
4) Measure the CKP sensor peak voltage in the
following procedures:
• Press the starter button and allow the engine to
crank for a few seconds, and then measure the
CKP sensor peak voltage.
5) Repeat the above procedures a few times and
measure the highest CKP sensor peak voltage.
CKP sensor peak voltage
4.5 V and more (G/W – Bl)
6) If the peak voltage measured on the ECM coupler is
lower than the standard value, measure the peak
voltage on the CKP sensor coupler as follows.
a) Disconnect the CKP sensor coupler (2).
b) Connect the multi-circuit tester with the peak
voltage adaptor.
