Test Dr-36A - Intermittent Injector Control Fault

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For appropriate wiring diagram, see WIRING DIAGRAMS at end of article.

Using DRB-II, erase fault codes. Start engine. Wiggle wiring harness from suspect fuel injector to Single Board Engine Controller (SBEC). If fault code returns, repair harness where wiggling caused fault code to return. Perform VERIFICATION PROCEDURE VER-2.
If fault code does not return, inspect related wiring harness connectors. Look for broken, bent, pushed-out or corroded terminals. Inspect related harnesses. Look for chafed, pierced or partially broken wire. If no defects exist, test is complete. Perform VERIFICATION PROCEDURE VER-2.
