Cold Cranking Test

For complete starter wiring circuit diagrams, refer to SYSTEM WIRING DIAGRAMS . The battery must be fully-charged and load-tested before proceeding. Refer to Battery  in 8, Battery.

1. Connect volt-ampere tester to battery terminals. See Fig 1. See instructions provided by manufacturer of volt-ampere tester being used.

2. Fully engage parking brake.
3. Place gearshift selector lever in Park position.
4. Verify that all lamps and accessories are turned off.
5. To prevent engine from starting, remove Fuel Pump Relay.
   WARNING: IF EQUIPPED WITH DIESEL ENGINE, ATTEMPT TO START ENGINE A FEW TIMES BEFORE PROCEEDING WITH FOLLOWING STEP.
6. Rotate and hold ignition switch in Start position. Note cranking voltage and current (amperage) draw readings shown on volt-ampere tester.
   • If voltage reads below 9.6 volts, refer to Starter Motor  in Diagnosis and Testing. If starter motor is OK, refer to Engine Diagnosis  in 9, Engine for further testing of engine. If starter motor is not OK, replace faulty starter motor.
   • If voltage reads above 9.6 volts and current (amperage) draw reads below specifications, refer to FEED CIRCUIT TEST  .
   • If voltage reads 12.5 volts or greater and starter motor does not turn, refer to CONTROL CIRCUIT TESTING  .
   • If voltage reads 12.5 volts or greater and starter motor turns very slowly, refer to FEED CIRCUIT TEST  .
7. Reinstall the fuel pump relay, and clear any fuel system DTCs that may have set as a result of the fuel pump relay being removed.
