Symptom: A new Odyssey left front door control switch can not control the right front door glass lift, but can control the drop. In the front door glass lift switch can be normal control up and down. 3 times before the replacement of the right front door glass lift switch, return to normal, but after several times the glass lift switch, the fault reproduction. Dismantling open and found damage to internal diodes.
Judgment method: check the right front door glass lifter normal, right front door switch and connecting lines normal. Left front door main switch connection is normal, check the instrument on the left side of the multi-channel controller is intact. As the right front door switch diode 3 burned out, you can exclude the cause of the switch is not caused. To determine the line may be short-circuit situation, after access to the circuit diagram and analysis, the focus check the left front door switch to the right front door switch connection line. After careful inspection, it was found that the insulation of the 9th line from the left front door to the right front door switch was damaged and a black line was installed next to the beam bundle.
Analysis of the reasons: 9 line insulation layer is damaged, the line directly take the money, quite a short circuit in the location, resulting in a one-way diode current is too large, resulting in breakdown.
Processing results: wrap the insulation layer on line 9 with a tape and replace the front right glass lift switch.
