Go to Step 2

Go to Starting System Check

1. Inspect the battery hydrometer. Refer to Battery Hydrometer Displays Dark or Yellow Dot .
2. Remove the INJR Fuse from the underhood junction block to prevent the engine from starting.
3. Using a J 39200 digital multimeter (DMM), measure the voltage between the battery terminals.
4. Place the ignition switch in START for 15 seconds.

Is the measured voltage within the specified range?

Greater than 8 V

Go to Step 3

Go to Step 7

Using a DMM, measure the voltage between the negative battery terminal and the engine block while the ignition switch is placed in START for 15 seconds.

Is the measured voltage within the specified range?

Less than 0.5 V

Go to Step 4

Go to Step 9

Using a DMM, measure the voltage between the positive battery terminal and the starter solenoid terminal B while the ignition switch is placed in START for 15 seconds.

Is the measured voltage within the specified range?

Less than 0.5 V

Go to Step 5

Go to Step 10

Replace the starter motor. Refer to Starter Motor Replacement .

Is the repair complete?

Go to Step 12

--

Perform the battery load test. Refer to Battery Not Operating Properly .

Does the battery test OK?

--

Go to Step 7

Go to Step 11

Perform the parasitic load test. Refer to Battery Electrical Drain/Parasitic Load Test .

Is the battery load test and repair complete?

--

Go to Step 8

--

Check the battery and starter motor terminals for corrosion or poor contact. If OK, replace the starter motor. Refer to Starter Motor Replacement .

Is the repair complete?

Go to Step 12

--

1. Clean the negative battery cable connections and repeat the test.
2. If the measured voltage is still greater than the specified value, replace the negative battery cable. Refer to Battery Cable Replacement .

Is the repair complete?

0.5 V

Go to Step 12

--

1. Clean the positive battery cable connections and repeat the test.
2. If the measured voltage is still greater than the specified value, replace the positive battery cable. Refer to Battery Cable Replacement .

Is the repair complete?

0.5 V
