(2)

Measure  the  resistance  between  injector  side  connector
terminal No. 1 and No. 2.

Standard value: 10.5 - 13.5 ohms [at 20°C (68°F)]

Q:Is the measured resistance between 10.5 and 13.5 ohms

[at 20°C (68°F)]?

YES:

 

Repair  harness  wire  between  the  intermediate  connector
B-21  (terminal  No.  6)  and  the  injector  connector  B-104
(terminal  No.  1)  and  harness  wire  between  injector
connector  B-104  (terminal  No.  2)  and  intermediate
connector B-21 (terminal No. 9) because of open circuit or
short circuit to ground or harness damage.
Then go to Step 10.

NO:

 Replace the No. 5 cylinder injector. Then go to Step

10.

STEP 8. Check for harness between the intermediate
connector B-21and the ECM connector B-10.

(1)

Disconnect  the  intermediate  connector  B-21  and  the  ECM
connector B-10.

(2)

Measure the resistance between the intermediate connector
B-21 (terminal No. 9) and the ECM connector B-10 (terminal
No. 50).

｠

Should be less than 2 ohms.

Q:Is the harness wire in good condition?

YES:

 Go to Step 9.

NO:

 Repair it. Refer to GROUP 00E, Harness Connector

Inspection P.13Aa-17. Then go to Step 10.

STEP 9. Using the oscilloscope, check the No. 5 cylinder
injector.

(1)

Disconnect the intermediate connector B-21 and connect the

NOTE: 

When measuring with the ECM side connector,

disconnect all ECM connectors. Connect the check harness
special tool (MB992110) between the separated
connectors. Then connect an oscilloscope probe to the
check harness connector terminal No. 50.

(3)

Start the engine and run at idle.

(4)

Measure the waveform.

｠

The waveform should show a normal pattern similar to the
illustration.

(5)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the waveform normal?

YES:

 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 10.

STEP 10. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  24  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0205 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.
