Without Scan Tool
WHEN USING THE VOLTMETER
(1) Connect an analog voltmeter across the diagnostic output terminal and ground terminal of the data link connector.
(2) Place the ignition switch in the ON position.
(3) Read the diagnostic trouble code on the basis of the deflection of the pointer of the voltmeter.
(4) Refer to the diagnostic chart and repair the defective point.
(5) Clear the diagnostic trouble codes in the same way as when a scan tool is used.
Connect a voltmeter to the diagnostic output terminal and the ground terminal of the data-link connector using the special tool. Observe the voltmeter pointer deflection to read out the diagnostic trouble codes.
DIAGNOSIS DISPLAY PATTERNS AND CODES
NOTE:
1. When two or more problems occur simultaneously, the three latest code numbers are displayed in the order of lowest code number first.
2. Even if the problem represented by the code number marked * occurs during cruise control operation, the cruise control mode will not be canceled.
3. When the system is normal, the diagnostic trouble code is displayed as described below.
1) If a scan tool is used:
