Toyota Tacoma (2015-2018) Service Manual: Cruise Control Input Processor (P160700)

Toyota Tacoma (2015-2018) Service Manual / Cruise Control / Dynamic Radar Cruise Control System(for 2gr-fks) / Cruise Control Input Processor (P160700)

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.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL
P160700	Cruise Control Input Processor	When prohibited by the sub-CPU, the dynamic radar cruise control system operates for 0.3 seconds or more.	ECM	Comes on

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 Cruise 1 / 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.

CAUTION / NOTICE / HINT

HINT:

The ECM receives signals from each sensor to control all functions of the dynamic radar cruise control system. When a DTC is detected, the fail-safe function remains on until the ignition switch is turned off.

PROCEDURE

1.	CHECK FOR DTCs

(a) Clear the DTCs.

Click here (b) Perform the following procedure.

(b) Perform the following procedure.

HINT:

If the following procedure is not performed, the previously output DTC cannot be detected.

Turn the ignition switch to ON.
Turn the dynamic radar cruise control system on using the cruise control main switch.
Wait for 1 second or more.
