Component Inspection
■ Component Resistance Check
1.

Ignition "OFF" & Engine "OFF".

2.

Disconnect HECU connector.

3.

Measure resistance between CAN LOW terminal and CAN HIGH terminal of the HECU harness connector.

Specification : Approx. 120 Ω

4.

Is the measured value within specifications?

▶ Fault is intermittent caused by poor connection in yaw rate & lateral G sensor harness and/or HECU's connector.

Go to "Verification of vehicle Repair" procedure.

▶ In case of the resistance "approx. 1Ω" : Repair mutual short in CAN signal circuit of the yaw rate & lateral G sensor and then go to "Verification of vehicle Repair" procedure.

In case of the resistance "∞ Ω" : Repair open in CAN signal circuit of the yaw rate & lateral G sensor and then go to "Verification of vehicle Repair" procedure.

If there is no problem in CAN signal circuit, Substitute with a known-good yaw rate & lateral G sensorand check for proper operation.

If problem is corrected, replace the yaw rate & lateral G sensor and then go to "Verification of Vehicle Repair" procedure.
