Diagnostic Procedure

If CKPS is faulty, Ignition spark could not ignited because ECM is not output ignition signal.

1.

Select oscilloscope function on the GDS and Connect channel A,B of the VMI to CKPS,CMPS signal harness.

2.

Check CKPS/CMPS signal waveforms with IG key "START".

■ Specification

note

This waveform is nothing but an example at certain condition. Thus, the real waveform could be different from this example.

3.

Are CKPS and CMPS signal waveforms normal?

▶ Go to "Ignition coil circuit inspection" procedure.

▶ Go to "ECM ground circuit inspection" procedure.
