#### Master Switch Input Test (cont'd)

22-37

4. With the connector still disconnected, make these input tests at the connector.

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.

Cavity | Wire | Test condition | Test: Desired result | Possible cause if result is not obtained
10 | BLK | Under all conditions | Check for continuity to ground: There should be continuity. |

- Poor ground (G501)
- An open in the wire

14
11 | GRN/WHT | Under all conditions | Check for voltage to ground: There should be battery voltage. |

- Blown No. 23 (20A) fuse in the under-dash fuse/relay box
- An open in the wire

12 | YEL/GRN | Ignition switch ON (II) | Check for voltage to ground: There should be battery voltage. |

- Blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box
- Blown No. 22 (20 A) fuse in the under-dash fuse/relay box
- Faulty power window relay
- An open in the wire

2 | GRN/BLK
7 | RED/YEL | Connect the No. 11 and No. 7 terminals, and the No. 4 and No. 14 terminals, and turn the ignition switch ON (II). | Check for driver's window motor operation: It should run (the driver's window moves down). |

- Faulty driver's window motor
- An open in the wire

4 | RED/BLK
3 | BLU/RED | Connect the No. 2 and No. 1 terminals, and the No. 3 and No. 10 terminals, and turn the ignition switch ON (II). | Check for front passenger's window motor operation: It should run (the front passenger's window moves down). |

- Faulty passenger's window motor
- Faulty passenger's window switch
- An open in the wire.

1 | BLU/WHT

5. Reconnect the 14P connector to the switch, and perform the following input tests.

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace the power window master switch.

Cavity | Wire | Test condition | Test: Desired result | Possible cause if result is not obtained
5 | RED/WHT | Ignition switch ON (II) | Check for voltage to ground: There should be battery voltage. |

- Faulty power window master switch
- An open in the wire

6 | LT GRN | Under all conditions | Check for voltage to ground: There should be battery voltage. |

- An open in the wire

13 | BLU | Ignition switch ON (II), and the driver's window switch AUTO DOWN | Check for voltage between the No. 13 and No. 6 terminals: There should be 0 V - about 5 V - 0 V - about 5 V repeatedly. |

- Blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box
- Blown No. 23 (20 A) fuse in the under-dash fuse/relay box
- Faulty power window relay
- Faulty power window master switch
- An open in the wire

8 | ORN | Ignition switch ON (II), and the driver's window switch AUTO DOWN | Check for voltage between the No. 8 and No. 6 terminals: There should be 0 V - about 5 V - 0 V - about 5 V repeatedly.
