STEP 10. Connector check: B-17X engine control 
relay connector

Q: Is the check result normal? 

YES : 

Check and repair harness between B-29 

(terminal No. 3) crank angle sensor 
connector and B-17X (terminal No. 1) 
engine control relay connector.

œ

Check power supply line for 
open/short circuit.

NO : 

Repair.

STEP 11. Measure resistance at B-29 crank angle 
sensor connector.

œ

Disconnect connector, and measure at harness 
side.

œ

Resistance between terminal No. 1 and earth.

OK: 2 

W

 or less

Q: Is the check result normal? 

YES : 

Go to Step 14 .

NO : 

Go to Step 12 .

STEP 12. Connector check: C-135 engine-ECU 
connector

Q: Is the check result normal? 

YES : 

Go to Step 13 .

NO : 

Repair.

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 

3

13A



), 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 .
