1. Inspect the battery hydrometer.
2. Remove the INJECTOR Fuse 7 from the IP Junction Block to prevent the engine from starting.
3. Place the ignition switch in CRANK for 15 seconds.
4. Using a DMM, measure the voltage between the battery terminals.

Is the measured voltage greater than the specified value?

8 V

Go to Step 2

Go to Step 5

2 | Using a DMM, measure the voltage between the negative battery terminal and the engine block while the ignition switch is placed in CRANK for 15 seconds. Is the measured voltage less than the specified value? | 0.5 V | Go to Step 3 | Go to Step 7
3 | Using a DMM, measure the voltage between the positive battery terminal and the starter solenoid terminal B while the ignition switch is placed in CRANK for 15 seconds. Is the voltage less than the specified value? | 0.5 V | Go to Step 4 | Go to Step 8
4 | Replace the starter motor. Refer to Starter Motor Replacement . Is the starter motor replacement complete? | -- | Go to Starting System Check | --
5 | Perform the parasitic load test. Refer to Battery Electrical Drain/Parasitic Load Test . Does the battery test OK? | -- | Go to Step 6 | Go to Step 9
6 | Check the battery and starter motor terminals for corrosion or poor contact. Refer to Battery Cable . If OK, replace the starter motor. Refer to Starter Motor Replacement . Is the repair completed? | -- | Go to Starting System Check | --
