Cold Cranking Test

NOTE:

For complete starter wiring circuit diagrams, refer to the Wiring Diagrams. The battery must be fully-charged and load-tested before proceeding. Refer to the appropriate Battery service information.

1 - POSITIVE CLAMP

2 - NEGATIVE CLAMP

3 - INDUCTION AMMETER CLAMP

Connect volt-ampere tester (1) and (2) to battery terminals. See instructions provided by manufacturer of volt-ampere tester being used. Note: Certain diesel equipped models use dual batteries. If equipped with dual battery system, tester should be connected to battery on left side of vehicle only. Also, tester current reading must be taken from positive battery cable lead that connects to starter motor.
Fully engage parking brake.
If equipped with manual transmission, place gearshift selector lever in Neutral position and block clutch pedal in fully depressed position. If equipped with automatic transmission, place gearshift selector lever in Park position.
Verify that all lamps and accessories are turned off.
To prevent a gasoline engine from starting, remove either the ignition run fuse, or the fuel pump control fuse. To prevent a diesel engine from starting, disconnect the electrical connectors at both the camshaft and crankshaft position sensors.
WARNING:
Attempt to start engine a few times before proceeding with following step.

NOTE:
A cold engine will increase starter current (amperage) draw reading, and reduce battery voltage reading.
Rotate and hold ignition switch in Start position. Note cranking voltage and current (amperage) draw readings shown on volt-ampere tester.
1. If voltage reads below 9.6 volts, refer to the appropriate Starter Motor service informaiton. If starter motor is OK, refer to the appropriate Engine Diagnosis service information for further testing of engine. If starter motor is not OK, replace faulty starter motor.
2. If voltage reads above 9.6 volts and current (amperage) draw reads below specifications, refer to Feed Circuit Test in this service informaiton.
3. If voltage reads 12.5 volts or greater and starter motor does not turn, refer to Control Circuit Testing in this service information.
4. If voltage reads 12.5 volts or greater and starter motor turns very slowly, refer to Feed Circuit Test in this service information.
