3. Select "Diagnostic Trouble Codes (DTC s)" mode and monitor "DTC Status" parameter.

4. Is the DTC B1605 present?

YES

Go to TERMINAL AND CONNECTOR INSPECTION procedure.

NO

Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and
ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending,
corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to
"VERIFICATION OF VEHICLE REPAIR" procedure.

TERMINAL AND CONNECTOR INSPECTION

Refer to DTC B1102.

SIGNAL CIRCUIT INSPECTION

1. Check CAN high communication circuit

1. Ignition "ON" and Engine "OFF".

2. Connect scan tool and select VEHICLE SCOPEMETER function.

3. Measure waveform between terminal "BCM-IF-30" of IPM and chassis ground.

Specification: CAN communication waveform is displayed

4. Is the measured waveform within specifications?

The existence of CAN communication waveform itself shows there's no trouble in CAN
communication circuit. If there's any short in harness, no signal is detected.

NO

Check for open or short in power harness. Repair as necessary and go to "VERIFICATION OF
VEHICLE REPAIR" procedure.

COMPONENT INSPECTION

1. Check DDM

1. Connect scan tool to Data Link Connector (DLC).

2. Ignition "ON" & engine "OFF".

3. Substitute with a known-good DDM and Check if the DTC is erased.

4. Is the DTC erased?

YES
