Retrieving Codes
- Turn ignition switch to OFF position. Using an analog voltmeter, connect voltmeter positive lead to Data Link Connector (DLC) terminal No. 5 (cruise control) and negative lead to terminal No. 12 (ground). See Fig 1
. DLC is located next to junction block, above left kick panel.
- Ensure all accessories are off. Turn ignition switch to ON position and Cruise Control Module (CCM) codes will be displayed. If 2 or more systems are non-functional, they will be displayed in numerical order.
- Codes are indicated by 12-volt pulses of voltmeter pointer. A constant repetition of 12-volt pulses indicates system is normal. If system is abnormal, voltmeter will pulse between zero and 12 volts. Signals will appear on voltmeter as long and short 12-volt pulses. Long pulses represent tens; short pulses represent ones.
- Check voltmeter reading against self-diagnostic display patterns and perform indicated test. See Figure
. If any codes are displayed, circuit malfunction may be present. Cruise control system is normal if code can be cleared.
