HOME Test 5.14 (Part 1

HOME Test 5.14 (Part 1 of 3) SYSTEM RELAY: DTC P1001, P1003 With relay in, check for battery voltage at Terminal 87 of system relay during first 2-3 seconds after key ON. Battery voltage (10-13 volts) present for 2-3 seconds after key ON? YES System relay OK. With relay out, measure resistance between Terminal 87 of the system relay and Socket A of Connector [83B]. Is resistance less than 0.5 ohm? 1 NO. No voltage or voltage always present. Check for 10-13 volts at Terminal 30 of the system relay. Voltage present? YES NO YES NO Recheck connections. Wiggle harness while repeating test. Repair intermittent. Locate and repair connection or open on Y/GN wire. With ignition ON, check for 10-13 volts at Terminal 86 of the system relay. Voltage present? Check for continuity to ground on BE/GY wire. Continuity present? YES NO 2 YES Measure resistance between Terminal 85 of system relay and Terminal 4 on Breakout Box. Is resistance less than 0.5 ohm? NO Was Ignition fuse blown? Locate and repair short to ground and replace ECM fuse. Locate and repair open between fuse and relay. YES NO YES NO Check for continuity to ground on Terminal 4 of Breakout Box. Continuity present? Locate and repair open on GN/O wire. Locate and repair short to ground and replace Ignition fuse. Locate and repair open on W/BK wire between Connector [22] and system relay. YES NO Locate and repair short to ground. Replace system relay. Does fuel pump run for the first 2 seconds after key ON?

Reprogram and learn password. 5-48 2004 Touring: Engine Management (EFI)

HOME Test 5.14 (Part 2 of 3) SYSTEM RELAY: DTC P1002 Remove system relay. Check for voltage on Terminal 4 of Breakout Box. Voltage present? YES NO Remove Breakout Box connector from ECM. Is voltage still present on Terminal 4? Replace system relay. YES NO Locate and repair short to voltage on GN/O wire. Replace ECM. Reprogram and learn password. Clear codes using speedometer self diagnostics. See 5.6 SPEEDOMETER SELF DIAGNOSTICS. Confirm proper operation with no check engine lamp. Test 5.14 (Part 3 of 3) SYSTEM RELAY: DTC P1004 Check connectors [13] (except FLHR/C/S) and [141] for corrosion, damaged terminals, improper wire location, or poor ground. Do any of these conditions exist? YES NO Repair. Condition: Fuel pump continues to run with key OFF. Remove system relay. Does pump continue to run? YES NO Locate and repair short to voltage on Y/GN wire. Replace system relay. Clear codes using speedometer self diagnostics. See 5.6 SPEEDOMETER SELF DIAGNOSTICS. Confirm proper operation with no check engine lamp. 2004 Touring: Engine Management (EFI) 5-49
