B210B-85-SYSTEM VOLTAGE LOW - SIGNAL ABOVE ALLOWABLE RANGE
For a complete wiring diagram, refer to the Wiring Information.
-
When Monitored:
Continuously with the ignition on.
-
Set Condition:
The Intrusion Transceiver Module (ITM) receives a high charging system voltage message over the CAN Bus or detects voltage over 16.5 volts on the (A412) Fused B(+) circuit.
Possible Causes |
|---|
| CHARGING SYSTEM VOLTAGE HIGH |
| INTRUSION TRANSCEIVER MODULE (ITM) |
1. CHECK PCM FOR CHARGING SYSTEM DTC
| 1. | With the scan tool, read the PCM DTCs. |
Are there any Charging System DTCs set in the PCM?
Yes
- Perform the Charging System diagnostic procedure. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Diagnosis and Testing).
No
- Go To 2
| 1. | With the scan tool, read the active ITM DTCs. |
Does the scan tool display this DTC as active?
Yes
- Replace the ITM in accordance with the Service Information.
- Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
No
- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
