SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P1607

DTC Code DTC Name
P1607 Cruise Control Input Processor

MONITOR DESCRIPTION

The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is functioning properly. If outputs from the CPUs are different and deviate from the standard, the ECM will illuminate the MIL and store the DTC immediately.

DTC No.

CONFIRMATION DRIVING PATTERN

  1. Turn the ignition switch off.

  2. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.

  3. Connect the cable to the negative (-) battery terminal.

  4. Turn the ignition switch to ON and wait for 16 seconds or more.

CAUTION / NOTICE / HINT

Tip:

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
