Variant Coding

The HECU is programmed with a variant code based on the vehicle powertrain configuration. This variant code is used to determine the appropriate ESC calculations. Variant code programming should be performed whenever an HECU is replaced.

Scheme 184: Procedure of Variant Coding
  1. Install a PCM (ECM & TCM)/ESC normally.
  2. Connect the GDS to the data link connector located underneath the crash pad.
  3. Select vehicle name.
  4. Select ANTI-LOCK BRAKE SYSTEM.
  5. Select the variant coding.
  6. Ignition "ON" & Engine "OFF".
  7. Perform variant coding.
  8. Ignition "OFF" and then ignition "ON".
  9. The variant coding is completed. CAUTION: If the warning lamp (ESC, EBD, ABS) is illuminated, follow the "Variant coding" again.

  1. STEP 1 The ESC analyzes the intention of the driver.
  2. STEP 2 It analyzes the movement of the ESC vehicle.
  3. STEP 3 The HECU calculates the required strategy, then actuates the appropriate valves and sends torque control requests via CAN to maintain vehicle stability.
