Ok, try this. Diagnostic connector next to fuse block. Using an analog voltmeter, connect voltmeter positive lead to self-diagnostic connector terminal #1 and negative lead to terminal #12. Turn ignition switch to on position and disclosure of ecu memory will begin. If 2 or more systems are non-functional, they are indicated by order of increasing code number. Indication is made by 12-volt pulses of voltmeter pointer. A constant repetition of short 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. For example, 4 long pulses and three short pulses indicate code 43.
