Cruise Control System: Functions

The cruise control has the following functions:

• Constant Speed Control
• Set
• Coast
• Accel
• Resume
• Low Speed Limit Control
• High Speed Limit Control
• Automatic Transmission Control
• Manual Cancel
• Auto Cancel
• Tap-Down Control
• Tap-Up Control
• Diagnosis
• Fail Safe

If the ECM detects a malfunction in the cruise control system, the ECU stores the malfunction data in memory, in addition to illuminating the cruise indicator light. Then, the DTCs can be accessed by connecting a hand-held tester to the DLC3 terminal or the Diagnosis Check Wire No. 2 (SST 09843-18040) to the Tc and CG terminals of the DLC3 and reading the blinking of the cruise indicator light.
