DESCRIPTION
When the hybrid vehicle control ECU detects that it is not functioning normally, DTC P160700 is stored.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | DTC Output from |
---|---|---|---|---|---|
P160700 | Cruise Control Input Processor | When the power switch is on (IG) 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. | Hybrid vehicle control ECU | Comes on | Hybrid Control |
MONITOR DESCRIPTION
The hybrid vehicle control ECU continuously monitors its main and sub CPUs. This self-check ensures that the hybrid vehicle control ECU is functioning properly. If outputs from the CPUs are different and deviate from the standard, illuminate the MIL and store the DTC immediately.

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 |
(a) Clear the DTCs.
Powertrain > Radar Cruise1 > 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.
