- Measure the voltage at each terminal (other than terminals 1M and 2A).
- If the voltage is not as specified in the Terminal Voltage Table, inspect the parts under "inspection item(s)" and related wiring harnesses.
- Disconnect the negative battery cable.
- If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the power, window main switch.
VOLTAGE CONTINUITY REFERENCE CHART
| Terminal | Signal name | Connected to | Measured condition | Voltage (V)/Continuity | Inspection item (s) |
|---|---|---|---|---|---|
| 1E | IG 1 | METER 10 A fuse | Ignition switch is at ON position | B+ |
|
| Ignition switch is at LOCK position | 1.0 or less | ||||
| 1F | Power-cut signal | Power window subswitch | Ignition switch at ON and power-cut switch at UNLOCK | B+ |
|
| 1G | Communication | Power window subswitch | Because this terminal is for communication, good/no good judgment by terminal voltage is not possible. |
|
|
| 1H | Communication | BCM | Because this terminal is for communication, good/no good judgment by terminal voltage is not possible. |
