Scania EMD DTC 112 Main mirror and wide-angle mirror heater element on the driver's side

EMD EMD control unit · Scania · 2 variants

Code 112 (decimal). Some diagnostic tools show it in hexadecimal as 0070.

In short

The main mirror and wide-angle mirror heater element on the driver's side H2 indicates an implausibly high temperature compared with the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).

Variant 1

Applies to: EMD0

What does Scania EMD fault code 112 mean?

The main mirror and wide-angle mirror heater element on the driver's side H2 indicates an implausibly high temperature compared with the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).

What causes Scania DTC 112?

- Fault in the main mirror and wide-angle mirror heater element on the driver's side H2. - Fault in the harness-to-component connectors or cable harness of the main mirror and wide-angle mirror heater element on the driver's side H2. - The main mirror and wide-angle mirror heater element on the driver's side H2 has been exposed to abnormally high temperatures compared with the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).

How to fix Scania EMD fault code 112?

  1. Compare the temperature between the main mirror and wide-angle mirror heater element on the driver's side H2, the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).
  2. Check the harness-to-component connectors and cable harness of the main mirror and wide-angle mirror heater element on the driver's side H2.
  3. Renew the main mirror and wide-angle mirror heater element on the driver's side H2.
  4. Verification To verify that the fault has been rectified, drive the vehicle at more than 30 km/h for more than 2 minutes.
  5. If the fault has been rectified, the fault code becomes inactive and can be cleared.

Variant 2

Applies to: EMD1

Detection

The main mirror and wide-angle mirror heater element on the driver's side H2 indicates an implausibly high temperature compared with the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).

Possible cause

Possible causes: - Fault in the main mirror and wide-angle mirror heater element on the driver's side H2. - Fault in the harness-to-component connectors or cable harness of the main mirror and wide-angle mirror heater element on the driver's side H2. - The main mirror and wide-angle mirror heater element on the driver's side H2 has been exposed to abnormally high temperatures compared with the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).

System reaction

If the vehicle is equipped with EGR, there is a risk that the EGR system will shut down at low ambient temperatures.

How to fix

  1. Compare the temperature between the main mirror and wide-angle mirror heater element on the driver's side H2, the main mirror and wide-angle mirror heater element on the passenger side H3 and the temperature sensor in the intake manifold (T126 or T202).
  2. Check the harness-to-component connectors and cable harness of the main mirror and wide-angle mirror heater element on the driver's side H2.
  3. Renew the main mirror and wide-angle mirror heater element on the driver's side H2.
  4. Verification To verify that the fault has been rectified, drive the vehicle at more than 30 km/h for more than 2 minutes.
  5. If the fault has been rectified, the fault code becomes inactive and can be cleared.
