B210B-SYSTEM VOLTAGE HIGH - DDM/PDM





For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL


- When Monitored:
At all times.

- Set Condition:
When the TIPM sends a message to the Door Module that the input voltage of the vehicle is above 16 volts for over 15 seconds, this code will set.






Diagnostic Test


1. CHECK ENGINE DTC's
With the scan tool, read ENGINE DTC's
Are there any BATTERY OR CHARGING SYSTEM DTC's present?

No


- Go To 2


Yes


- Diagnose and repair the DTC(s)


2. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Start the engine and run for two minutes.
With the scan tool, read DTC's in the Door Module.
Does the scan tool display B210B-SYSTEM VOLTAGE HIGH?

Yes


- Go To 3


No


- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test.


3. CHECK THE DOOR TRACK HARNESS VOLTAGE
Stop the engine.
Turn the ignition on.
Using the scan tool, read and record the Battery Voltage of the Door Module.
Turn the ignition off.
Disconnect the Door Module C3 connector.
Turn the ignition on.
Using a voltmeter, measure the voltage between the (A214/5) Fused B(+) circuit and the (Z908/9) Ground in the Door Module C3 connector (cavities 4 and 5).
Does the measured voltage differ from the scan tool voltage by more than one (1.0) volt?

Yes


- Replace the Power Sliding Door Module.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test.


No


- Compare this voltage reading to direct battery voltage. If the voltage differs by more than one volt, repair the wiring. If it doesn't - test complete.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test.
