## INSPECTION PROCEDURE

1.INSPECT FUSE (ECU-IG & GAUGE)

1. Remove the ECU-IG & GAUGE fuse from the instrument panel junction block (driver side junction block).

1. Measure the resistance of the fuse.

   Standard resistance:
     Below 1 Ω

| NG |

REPLACE FUSE

OK |

2.CHECK WIRE HARNESS (ACCESSORY METER*1 OR TELL TAIL LIGHT*2 - BATTERY AND GROUND)

1. Disconnect the A27*1 meter connector.

1. Disconnect the P13*2 light connector.

1. Measure the voltage of the wire harness side connector.

   Standard voltage:

     w/ Accessory meter assembly
     Tester Connection | Condition | Specified Condition
     A27-12 (IG) - Body ground | Ignition switch ON | 10 to 14 V
     A27-12 (IG) - Body ground | Ignition switch OFF | Below 1 V

   w/o Accessory meter assembly:

     Tester Connection | Condition | Specified Condition
     P13-3 - Body ground | Ignition switch ON | 10 to 14 V
     P13-3 - Body ground | Ignition switch OFF | Below 1 V

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     w/ Accessory meter assembly
     Tester Connection | Specified Condition
     A27-1 (GND) - Body ground | Below 1 Ω
     A27-10 (SGND) - Body ground | Below 1 Ω

   w/o Accessory meter assembly:

     Tester Connection | Specified Condition
     P13-1 - Body ground | Below 1 Ω

   HINT:
     *1: w/ Accessory meter assembly (multi-display)
     *2: w/o Accessory meter assembly (multi-display)

| NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK |

3.INSPECT FRONT SEAT INNER BELT ASSEMBLY (PASSENGER SIDE)

1. Disconnect the F17 belt connector.

1. Measure the resistance of the belt.

   Standard resistance:

     Tester Connection | Condition | Specified Condition
     1 - 2 | Seat belt is unfastened (ON) | Below 100 Ω
     1 - 2 | Seat belt is fastened (OFF) | 1 MΩ or higher

| NG |

Go to step 6

OK |

4.CHECK WIRE HARNESS (FRONT SEAT INNER BELT ASSEMBLY - BODY GROUND)

1. Disconnect the F17 belt connector.

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     Tester Connection | Specified Condition
     F17-2 - Body ground | Below 1 Ω

| NG |

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK |

5.CHECK WIRE HARNESS (SEAT INNER BELT - ACCESSORY METER*1 OR TELL TAIL LIGHT*2)

1. Disconnect the F17 belt connector.

1. Disconnect the A27*1 meter connector.

1. Disconnect the P13*2 light connector.

1. Measure the resistance of the wire harness side connectors.

   Standard resistance:

     w/ Accessory meter assembly
     Tester Connection | Specified Condition
     F17-1 - A27-8 (PBEW) | Below 1 Ω

   w/o Accessory meter assembly:

     Tester Connection | Specified Condition
     F17-1 - P13-3 | Below 1 Ω

   HINT:
     *1: w/ Accessory meter assembly (multi-display)
     *2: w/o Accessory meter assembly (multi-display)

Result:

  Result | Proceed to
  OK (w/ Accessory meter assembly) | A
  OK (w/o Accessory meter assembly) | B
  NG | C

| B |

REPLACE TELLTAIL LIGHT ASSEMBLY

| C |

REPAIR OR REPLACE HARNESS AND CONNECTOR

A |

REPLACE ACCESSORY METER ASSEMBLY (MULTI-DISPLAY)

6.INSPECT FRONT SEAT INNER BELT ASSEMBLY (OCCUPANT DETECTION SENSOR)

1. Disconnect the A sensor connector.

1. Measure the resistance of the sensor.

   Standard resistance:

     Tester Connection | Condition | Specified Condition
     1 - 2 | Apply more than 147 N (15 kgf, 22 lbf) force to occupant detection sensor | Below 100 Ω
     1 - 2 | No force applied to occupant detection sensor | 1 MΩ or higher

| NG |

REPAIR FRONT SEAT CUSHION PAD

OK |

REPLACE FRONT SEAT INNER BELT ASSEMBLY (PASSENGER SIDE)
