1.CHECK E-SUS CONTROL UNIT POWER SUPPLY

1. Turn the ignition switch OFF.
2. Disconnect the E-SUS control unit harness connector.
3. Check the voltage between the E-SUS control unit harness connector.

   E-SUS control unit | Voltage
   Connector | Between terminals
   M110 | 23 – 22 | Battery voltage
   19 – 22 | 0 V

4. Turn the ignition switch ON.
   ■ CAUTION ■
   Never start engine.
5. Check the voltage between the E-SUS control unit harness connector.

   E-SUS control unit | Voltage
   Connector | Between terminals
   M110 | 23 – 22 | Battery voltage
   19 – 22

Is the inspection result normal?
YES>>GO TO 2.
NO>>
Check the following items, and repair or replace the malfunctioning parts.
