STEP 13. Check harness between B-29 (terminal
No. 1) crank angle sensor connector and C-135
(terminal No. 40) engine-ECU connector.

NOTE: Before checking harness, check intermediate
connector C-16, and repair if necessary.

œ

Check earthing line for open circuit and damage.

Q: Is the check result normal?

YES :

Go to Step 8 .

NO :

Repair.

STEP 14. Measure output waveform at B-29 crank
angle sensor connector (Use oscilloscope).

œ

Use special tool test harness (MB998478) to con-
nect connector, and measure at pick-up harness.

œ

Engine: Idling

œ

Transmission: Neutral

œ

Voltage between terminal No. 2 and earth.

OK: Waveforms should be displayed on
Inspection procedure using an oscilloscope
(Refer to

), its maximum value

should be 4.8 V or more, and its minimum
value should be 0.6 V or less with no noise in
waveform.

Q: Is the check result normal?

YES :

Go to Step 8 .

NO :

Go to Step 15 .
