DTC type definitions (AWR6B45)

There are 4 DTC types: Type A, B, C, and E. Among these DTCs, type A and B DTCs are related to emission whereas type C and E DTCs are related to items other than emission.

1. Action taken when DTC sets - Type A

  • The TCM flashes the check trans warning light when the diagnostic runs and fails.
  • The TCM requests the MIL to be illuminated when the diagnostic runs and fails.
  • The TCM records the operating conditions at the time the diagnostic fails. The TCM stores this information in the Failure Records.
  • The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Freeze Frame/Failure Records.
  • The ECM stores DTC P0700 in ECM history at the time the diagnostic fails.

2. Action taken when DTC sets - Type B

  • The TCM flashes the check trans warning light on the second driving cycle when the diagnostic runs and fails.
  • The TCM requests illumination of the MIL on the second driving cycle when the diagnostic runs and fails.
  • The TCM records the operating conditions at the time the diagnostic fails. The TCM stores this information in the Failure Records.
  • The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Freeze Frame/Failure Records.
  • The ECM stores DTC P0700 in ECM history during the second driving cycle in which the diagnostic fails.

3. Condition for clearing the MIL, check trans warning light/DTC - Type A or Type B

  • The TCM turns OFF the check trans warning light and cancels the MIL request after the third driving cycle when the diagnostic runs and does not fail.
  • The DTC history is cleared after 40 consecutive warm-up cycles when the diagnostic runs and does not fail.
  • Clear the MIL, check trans warning light, and the DTC with a scan tool.

4. Action taken when DTC sets - Type C

  • The TCM flashes the check trans warning light when the diagnostic runs and fails.
  • The TCM records the operating conditions at the time the diagnostic fails. The TCM stores this information in the Failure Records.

5. Condition for clearing the check trans warning light/DTC - Type C

  • The TCM turns OFF the check trans warning light after the third driving cycle when the diagnostic runs and does not fail.
  • The current DTC clears after the third driving cycle when the diagnostic runs and passes.
  • The DTC history is cleared after 40 consecutive warm-up cycles when the diagnostic runs and does not fail.
  • Clear the check trans warning light and the DTC with a scan tool.

6. Action taken when DTC sets - Type E

  • The TCM does not flash the check trans warning light.
  • The TCM records the operating conditions at the time the diagnostic fails. The TCM stores this information in the Failure Records.

7. Condition for clearing the check trans warning light/DTC - Type E

  • The current DTC clears after the first driving cycle when the diagnostic runs and passes.
  • The DTC history is cleared after 40 consecutive warm-up cycles when the diagnostic runs and does not fail.
  • Clear the DTC with a scan tool.
