| 1 | Did you perform the Diagnostic System Check for Starting and Charging? | - | Go to Step 2 | Go to Diagnostic System Check - Engine Electrical |
| 2 | Start the engine. Does the battery charge indicator remain illuminated after the 5 second bulb check? |
- | Go to Step 3 | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems |
| 3 | Measure the voltage across the battery terminals. Is the battery voltage greater the specified value? |
11 V | Go to Step 4 | Go to Charging System Test |
| 4 |
|
B+ | Go to Step 5 | Go to Step 6 |
| 5 | With a scan tool, observe the Ignition 1 parameter in the powertrain control module (PCM) data list. Does the scan tool indicate the battery voltage equals the specified value? |
B+ | Go to Step 11 | Go to Step 7 |
| 6 | Measure the voltage between the BCM battery positive voltage circuit supplied by the 10A Cluster/BCM fuse and ground. Does the voltage equal the specified value? |
B+ | Go to Step 10 | Go to Step 8 |
| 7 | Measure the voltage between the PCM voltage supply circuit and ground. Does the voltage equal the specified value? |
B+ | Go to Step 12 | Go to Step 9 |
| 8 | Test battery positive voltage circuit supplied by the 10A Cluster/BCM fuse to the BCM for a high resistance or an open. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Did you find and correct the condition? |
- | System OK | Go to Step 10 |
| 9 | Test the battery positive voltage circuit of the PCM for a high resistance or an open. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Did you find and correct the condition? |
- | System OK | Go to Step 12 |
| 10 | Replace the BCM. Refer to Body Control Module Replacement
n Body Control System. Did you complete the replacement? |
- | System OK | - |
| 11 | Replace the instrument panel cluster (IPC). Refer to Instrument Panel Cluster (IPC) Replacement
in Instrument Panel, Gages and Console. Did you complete the replacement? |
- | System OK | - |
| 12 | Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement
in Engine Controls - 3.4L or Powertrain Control Module (PCM) Replacement
in Engine Controls - 3.8L (L36 and L67). Did you complete the replacement? |
- | System OK | - |
