Circuit Diagram 22A-112


Ignition Key Switch Test 22A-113

NOTE: For more key-in beeper information, refer to the circuit diagram (see page 22A-122) and input test (see page 22A-124) .

When the ignition key is in the ignition switch, the key-in beeper circuit of multiplex control unit senses ground through the closed ignition key switch. When you open the driver's door, the beeper circuit senses ground through the closed door switch. When both switches are closed (driver's door and ignition), the key-in beeper in the gauge assembly is activated.

  1. Remove the steering column upper and lower covers (see page 17-24) .
  2. Disconnect the 6P connector.


  3. Check for continuity between the No. 1 and No. 2 terminals.
  4. There should be continuity with the key in the ignition switch.
  5. There should be no continuity with the key removed.
  6. If the continuity is not as specified, replace the steering lock assembly.

Ignition Key Light Test 22A-113

  1. Remove the steering column upper and lower covers (see page 17-24) .
  2. Disconnect the 6P connector.


  3. The LED should come on when power is connected to the No. 6 terminal and ground is connected to No. 5 terminal.

Control Unit Input Test 22A-114

  1. Before testing, troubleshoot the multiplex control system (see page 22A-269) .
  2. Remove the dashboard lower cover.
  3. Disconnect the under-dash fuse/relay box connectors.
  4. NOTE: All connectors are wire side of female terminals.


  5. Inspect the connector and socket terminals to be sure they are all making good contact.
  6. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
  7. If the terminals look OK, go to step 5.

22A-115

  1. With the connectors still disconnected, make these input tests at the connector.
  2. If any test indicates a problem, find and correct the cause, then recheck the system.
  3. If all the input tests prove OK, go to step 5.

    Test condition

    Test: Desired result

    Possible cause if result is not obtained

    K2 BLU/ORN Under all conditions Check for continuity between the K2 terminal and the keyless receiver unit 5P connector No. 2 terminal: There should be continuity.

  8. Reconnect the connectors to the under-dash fuse/relay box, and make sure these input tests at the appropriate connectors on the under-dash fuse/relay box.
  9. If any test indicates a problem, find and correct the cause, then recheck the system.
  10. If all the input tests prove OK, the multiplex control unit must be faulty, replace the under-dash fuse/relay box assembly.
