P160700 | Cruise Control Input Processor |
When the ignition switch is ON and control of vehicle speed by the dynamic radar cruise control system is prohibited by the sub-CPU, the dynamic radar cruise control system operates for 0.3 seconds or more. |
ECM | Comes on |
Cruise Control |
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, illuminate the MIL and store the DTC immediately.

- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the Techstream off.
- Turn the ignition switch off.
- Disconnect the Techstream.
- Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
- Connect the cable to the negative (-) battery terminal.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Turn the cruise control main switch on.
- Wait 16 seconds or more.[*1]
HINT:
[*1] : Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Radar Cruise1 / Trouble Codes.
- Read the DTCs.
HINT:
- If a DTC is output, the system is malfunctioning.
- If a DTC is not output, perform the following procedure.
- If the DTCs are not output, perform a universal trip and check for permanent DTCs.

HINT:
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTCs are output, the system is normal.

HINT:
Read the freeze frame data using the Techstream. When a malfunction is detected, various engine control parameters are stored as freeze frame data and can be useful for troubleshooting.
PROCEDURE
| 1. |
CHECK FOR DTCs (Radar Cruise1) |
(a) Clear the DTCs.
Powertrain > Cruise Control > Clear DTCs(b) Make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the system cannot detect the malfunction.
(c) Check for DTCs.
