• Code: H3-02
• Description: Sub thermistor fusing section high temperature trouble (TH_US)
  The fusing temperature inside the PWB exceeds the specified level.
• Causes: Thermistor trouble, control PWB trouble, fusing section connector connection error, AC power source trouble
• Remedy: 1) Use SIM5-2 to check blinking of the heater lamp. 2) If it blinks normally, check the thermistor and the harness. Check the control PWB thermistor input circuit section. 3) If the heater lamp keep lighting, check the AC PWB and the control PWB lamp control circuit. 4) Use SIM14 to cancel the trouble.

• Code: H3-04
• Description: Fusing section high temperature trouble (TH_US)
  The temperature of the hung-up prevention thermistor exceeds the specified level.
• Causes: Non-contact thermistor trouble, control PWB trouble, fusing section connector connection error, AC power source trouble
• Remedy: 1) Use Sim44-14 to check if the non-contact thermistor shows an abnormal temperature. If the display is normal, use Sim5-2 to check the blinking operation of the heater lamp. <1> If it blinks normally, check the thermistor and the harness. Check the control PWB thermistor input circuit section. <2> If the heater lamp keep lighting, check the AC PWB and the control PWB lamp control circuit. 2) Use SIM14 to cancel the trouble.

• Code: H4-00
• Description: Fusing section low temperature trouble (TH_UM_AD2)
  The temperature does not reach the specified level within the specified time after turning on the power relay.
• Causes: Thermistor trouble, heater lamp trouble, PCU PWB trouble, thermostat trouble, AC power source trouble, interlock switch trouble
• Remedy: 1) Use SIM5-2 to check blinking of the heater lamp. 2) If it blinks normally, check the thermistor and the harness. Check the control PWB thermistor input circuit section. 3) If it is not lighted, check for the heater lamp disconnection and the thermostat breakage. Check the interlock switch. Check the AC PWB and the PCU PWB lamp control circuit. 4) Use SIM14 to cancel the trouble.

• Code: H4-01

• Code: H5-01
• Description: 5 continuous detection of POD1 notreached jam
  5 continuous detection of POD1 not-reached jam
• Causes: The fusing jam is not removed completely. (Jam paper remains.) POD1 sensor trouble or harness connection trouble Fusing unit installation trouble
• Remedy: Case 1 Cause The fusing jam is not removed completely. (Jam paper remains.) Check and remedy Check the fusing section for jam paper. (winding, etc.) Case 2 Cause POD1 sensor trouble or harness connection trouble Check and remedy Check the POD1 sensor harness. Use SIM14 to cancel the trouble. Case 3 Cause Fusing unit installation trouble Check and remedy Check the fusing unit installation.

• Code: L1-00
• Description: Mirror feed trouble
  Mirror feed is not completed within the specified time.
• Causes: Mirror unit trouble, mirror wire disengagement
• Remedy: Use SIM1-1 to check the mirror operation.
