  • A    Cable reel 6 – P connector
  • B    Test Harness C – SMD 4089
  1. Remove dashboard lower cover and disconnect cable reel 6 – P connector from SRS main harness.
  2. Connect Test Harness C to the cable reel 6 – P connector.
  3. Check for continuity between No. 4 terminal of Test Harness C and earth, between No. 5 terminal and earth:

  • A    SRS main harness 18 – P connector
  • B    SRS unit
  • C    Test Harness B – SMD 4088
  • D    Jumper wires – SMD 4087
  1. Connect voltmeter between terminals No. A1 (+) and No. A5 (–) of Test Harness B.
  2. Turn ignition ON (II) and measure voltage, which should be 9.4 – 14 V.
  3. Connect voltmeter between terminals No. A7 and No. A5 of Test Harness B and measure voltage, which should be 0.5 V or less.

If voltage is less than 0.5 V, go to Test 3.

If voltage is more than 0.5 V, SRS unit is faulty. Replace the unit.
