1.

Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

2.

Thoroughly check all connectors(and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

3.

Has a problem been found?

	▶ Repair or replace as necessary and then, Go to "Verification of Vehicle Repair" procedue.
	▶ Go to "Charging System Inspection" procedure.

1.

Start the engine and turn the headlight, rear window defogger and all other electrical devices.

2.

Measure voltage between (+) terminal and (-) terminal of battery while maintaining ENG. RPM at 2500 RPM.

Specification : Approx 14.5 V

Fig.1) GDS Multimeter voltage check

3.

Is the parameter displayed within specifications?

▶ Go to "Power Circuit Inspection" procedure.

▶ Check for tension of drive belt, fuse, terminal of battery, all terminals of alternator are in good condition and check for damaged harness and poor connection between alternator and battery.

▶ Repair or replace as necessary and then, Go to "Verification of Vehicle Repair" procedue.

1.

Ignition "OFF".

2.

Disconnect SPAS ECU harness connector.

3.

Ignition "ON".

4.

Measure voltage between Pin No.13(IG1) of SPAS ECU harness connector and the chassis ground.

Specification : Battery (+) Voltage

Fig.1) GDS Multimeter voltage check

5.

Is the measured value within specifications?

	▶ Go to "Ground Circuit Inspection" procedure.
	▶ Repair open or short in power circuit between battery and SPAS ECU harness connector and then go to "Verification of Vehicle Repair" procedure.

1.

Ignition "OFF".

2.

Disconnect SPAS ECU connector.

3.

Measure resistance between Pin No.24(ground) of the SPAS ECU harness connector and chassis ground.

Specification : Below approx. 1Ω

Fig.1) GDS Multimeter resistance check

4.

Is the measured resistance within specifications?

▶ Fault is intermittent caused by poor contact in the sensor’s and/or SPAS ECU connector or was repaired and SPAS ECU memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.

▶ Carefully re-do this troubleshooting guide steps.

▶ If no problems were found with the circuits or connectors, replace the SPAS ECU and go to "Verification of Vehicle Repair" procedure.

▶ In case SPAS ECU is replaced, Refer to "DTC Inspection" procedure in DTC 1702 and perform SPAS Variant coding in the "Vehicle S/W Management" with GDS.
