DESCRIPTION
The cruise control main switch operates 8 functions: SET, - (COAST), TAP-DOWN, RES (RESUME), + (ACCEL), TAP-UP, CANCEL, and MODE. The SET, TAP-DOWN, and - (COAST) functions, and the RES (RESUME), TAP-UP, and + (ACCEL) functions are operated with the same switch. The cruise control main switch is an automatic return type switch which turns on only while operating it in the direction of each arrow and turns off after releasing it. The internal contact point of the cruise control main switch is turned on with the switch operation. The ECM then reads the voltage value that has been changed by the switch operation to control MODE, SET, - (COAST), RES (RESUME), + (ACCEL), and CANCEL. The dynamic laser cruise control system has two cruise control modes: the constant speed control mode and vehicle-to-vehicle distance control mode.

INSPECTION PROCEDURE
1 READ VALUE OF INTELLIGENT TESTER
ECM (Cruise control):
OK: When the cruise control main switch is operated, the display changes as shown above.
Result
2 INSPECT CRUISE CONTROL MAIN SWITCH
Standard resistance
3 INSPECT HARNESS AND CONNECTOR (CRUISE CONTROL MAIN SWITCH - SPIRAL CABLE)
Standard resistance
4 INSPECT SPIRAL CABLE
NOTICE: The spiral cable is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable may prevent the airbag from deploying. Be sure to read the page shown in the brackets.
HINT:
Standard resistance
HINT: The spiral cable makes a maximum of approximately 5 rotations
5 CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - ECM)
Standard resistance
REPLACE ECM
Room temperature sensor (for rear air conditioning system)
ON-VEHICLE INSPECTION
1. INSPECT REAR A/C ROOM TEMPERATURE SENSOR
(a) Remove the rear A/C room temperature sensor.
(b) Disconnect the connector from the rear A/C room
temperature sensor.
(c) Measure the resistance according to the value(s) in
the table below.

Check mode procedure
HINT:
Intelligent tester only:
Compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
NOTICE:
All the stored DTCs and freeze frame data are erased if:

DTC B1637/85 Short to GND in Rear Curtain Shield Squib LH
Circuit
DESCRIPTION
The rear curtain shield squib LH circuit consists of the center airbag sensor
assembly and the curtain
shield airbag assembly LH.
The circuit instructs the SRS to deploy when deployment conditions are met.
