Code 36: Ignition Timing Adjustment Signal

NOTE: For component terminal identification, see TERMINAL IDENTIFICATION . For wiring diagrams, see WIRING DIAGRAMS article in the ENGINE PERFORMANCE Section.

Turn ignition switch to ON position. Using DVOM, check voltage at ignition timing adjustment terminal (located at firewall) with terminal grounded and ungrounded. With terminal grounded, voltage should be 0-1.0 volt. With terminal ungrounded, voltage should be 4.0-5.5 volts. If voltage is not as specified, repair ignition timing adjustment terminal wiring harness or connector as necessary. If voltage is as specified, replace ECM.
