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.
A. Specification : Approx. 120 Ohms




4. Is the measured value within specifications ?
YES
1) Fault is intermittent caused by poor connection in Yaw Rate & Lateral G sensor harness and/or HECU's connector or was repaired and HECU memory was not cleared.
Go to "Verification of vehicle Repair" procedure.
NO
1) Substitute with a known-good Yaw Rate & Lateral G sensor and check for proper operation.
If problem is corrected, replace Yaw Rate & Lateral G sensor and then go to "Verification of Vehicle Repair" procedure.
In case of the resistance "Infinity Ohms" : 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 sensor and check for proper operation.
If problem is corrected, replace the yaw rate & lateral G sensor and then go to "Verification of Vehicle Repair" procedure.
