Master Switch Input Test (cont'd)

22-37  

  1. 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
  1. 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.
