ERRoR CodE 01AC
1) SyMPToM:
a. 01AC - Electro magnet (ECB) over current.
2) SolUTIoN:
a. On standby mode, measure the resistance on ECB1 and ECB2. Please check the ECB extension cable connection at the LCB (pins 1 &
3 for ECB1, pins 2 & 4 for ECB2), there should be between 12.8 ~ 14.2 ohms. (Figure A)
- If the ECB resistance is out of the range, replace the ECB.
- If the ECB resistance is within the range, replace the LCB.
b. Check the gap of ECB1 and ECB2. There should be a gap of .5mm between the ECB and the flywheel.
- Adjust the gap as shown in Section 9.16.
