pump relay. See appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM
WIRING DIAGRAMS. Resistance should be a maximum of 1.5 ohms. If resistance is not okay, repair as
necessary. Verify repair. Test is complete. If resistance is okay and all wiring is okay, replace faulty
ECM. See ENGINE CONTROL MODULE REMOVAL & INSTALLATION . After repairs, erase
DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See TEST DRIVE
RELEARN PROCEDURE .

Test Requirements
Ensure all fuses are okay, battery voltage is at least 11.5 volts and fuel pump relay is okay. Ensure all electrical
accessories are off and A/C is off. Ensure engine is mechanically sound. Ensure no intake or exhaust system
leaks exist. Ensure engine coolant temperature is at least 176°F (80°C).
Test Procedure
1. For Beetle (engine code AWV), go to next step. For all models except Beetle (engine code AWV).
Connect scan tool. See RETRIEVING DIAGNOSTIC TROUBLE CODES . Using scan tool, check
activation of fuel injectors. See OUTPUT DIAGNOSTIC TEST MODE . All fuel injectors should
audibly click. If any fuel injector does not click, go to next step. If all fuel injectors click, go to step 7 .
2. Turn ignition off. Disconnect fuel injector harness connectors. Using DVOM, measure resistance between
fuel injector terminals. See Fig. 35 . Resistance must be 12-17 ohms at room temperature, (resistance
should be greater than 12-17 ohms at engine operating temperature). If fuel injector resistance is okay,
leave fuel injector harness connectors disconnected and go to next step. If fuel injector resistance is not
okay, replace faulty fuel injector(s). See FUEL SYSTEM in appropriate REMOVAL, OVERHAUL &
INSTALLATION article. After repairs, erase DTC memory. Verify repair. Test is complete. Perform
ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
NOTE:
Output Diagnostic Test Mode is used when using Scan Tools VAG 1551/1552 or
VAS 5051/5052, always continue with output diagnostic test mode until last
component in output diagnostic test mode test sequence has been checked. If
you are not using Scan Tools VAG 1551/1552 or VAS 5051/5052 follow scan tool
manufacturer's instructions.
NOTE:
When using scan tool to activate fuel injectors, they are barely audible. Use
mechanics stethoscope if necessary. Beetle (engine code AWV) does not have
an Output Diagnostic Test Mode for activating fuel injectors.
