PROCEDURE
1. INSPECT CRUISE CONTROL MAIN SWITCH
(a) w/o Dynamic Radar Cruise Control System:
(1) Measure the resistance according to the value(s) in the table below.
| *a | Component without harness connected (Cruise Control Main Switch) | - | - |
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 1 (ECC) - 3 (CCS) | Cruise control main switch (ON-OFF button) released | 1 MΩ or higher |
| Cruise control main switch (ON-OFF button) pushed | Below 2.5 Ω | |
| +RES switch ON | 236 to 244 Ω | |
| -SET switch ON | 618 to 642 Ω | |
| CANCEL switch ON | 1510 to 1570 Ω |
If the result is not as specified, replace the cruise control main switch.
