LAN-138 < DTC/CIRCUIT DIAGNOSIS > [CAN SYSTEM (TYPE 2)] HV BAT BRANCH LINE CIRCUIT 3. Measure voltage between high voltage harness connector terminals and PTC heater harness connector terminals. DANGER:
Touching high voltage components without using the appropriate protective equipment will cause electrocution. CAUTION: For voltage measurements, use a tester which can measure to 500 V or higher. >> GO TO 4. 4. CHECK POWER SUPPLY AND GROUND CIRCUIT Check the power supply and the ground circuit of the Li-ion battery controller. Refer to . Is the inspection result normal? YES >> GO TO 5. NO >> Repair the power supply and the ground circuit. 5. CHECK HARNESS FOR OPEN CIRCUIT 1. Remove Li-ion battery controller. Refer to EVB-201, "LI-ION BATTERY CONTROLLER : Removal and . 2. Check the continuity between vehicle communication harness (harness between Li-ion battery harness connector side and Li-ion battery controller side) connector terminals. Refer to . Is the measurement value within the specification? YES (Present error)>>Replace the Li-ion battery controller. Refer to TROLLER : Removal and Installation" . YES (Past error)>>Error was detected in the Li-ion battery controller branch line. NO >> Repair the vehicle communication harness.
