1.

Many malfunctions in the electrical system are caused by poor harness(es) and terminal condition. Faults can also becaused by interference from other electrical systems, and mechanical systems or chemical damage.

2.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

3.

Has a problem been found?

	▶ Repair as necessary and then go to "Verification of Vehicle Repair" Procedure.
	▶ Go to CAN communication Inspection procedure.

1.

Install all the control unit (Module)

2.

Ignition "ON"& Engine "OFF"

3.

Measure signal waveform between C-CAN-HIGH connector of SPAS ECU and chassis ground.

4.

Measure signal waveform between C-CAN-LOW connector of SPAS ECU and chassis ground.

Specification : Refer to Signal waveform at Reference Data in General Information

5.

Is the measured value within specifications?

▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage in the SPAS ECU and TCM. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known-good Sampe of TCM and check for proper peration.

If problem is corrected, replace TCM and then go to "Verification of Vehicle Repair" procedure.

▶ If the measured value is battery voltage, check that it is short to battery in the circuit. Then, go to "Verification of Vehicle Repair" procedure. And then, go to "Verification of Vehicle Repair" procedure. In case that Communication is in sleep mode, 12V will be measured. Therefore, check that communication is in Wake up status.

▶ If the measured value is approx. "0V', check that it is short to ground, open or short in CAN High & Low. Then, go to "Verification of Vehicle Repair" procedure.
