2. Turn the ignition switch ON.
3. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
4. With operating the test items, check the voltage between the IPDM E/R harness connector and the ground.

   Terminals | Test item | Voltage (Approx.)
   (+) | (−)
   IPDM E/R | Ground | EXTERNAL LAMPS
   Connector | Terminal
   E5 | 7 | TAIL | Battery voltage
   Off | 0 V

Is the measurement value normal?
YES>>GO TO 3.
NO>>Replace IPDM E/R.
3.CHECK TAIL LAMP OPEN CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between the IPDM E/R harness connector and the rear combination lamp harness connector.

   IPDM E/R | Rear combination lamp | Continuity
   Connector | Terminal | Connector | Terminal
   RH | E5 | 7 | B240 | 2 | Existed
   LH | B57 | 2

Does continuity exist?
YES>>GO TO 4.
NO>>Repair the harnesses or connectors.
4.CHECK TAIL LAMP GROUND OPEN CIRCUIT
