Sunroof
B210D-BATTERY VOLTAGE LOW - SUNROOFWHEN MONITORED
At all times.
SET CONDITION
Anytime the module senses voltage input below 9.0 volts (motor operating or not). After this code is set, it becomes stored when the voltage exceeds 9.1 volts.
POSSIBLE CAUSES
- Low voltage engine DTC
- (A932) fused B(+) circuit resisted
- Sunroof motor/module
DIAGNOSTIC TEST
1. CHECK ENGINE DTC's
NOTE: Ensure the battery is fully charged before proceeding.
With the scan tool, read ENGINE DTC's
Q: Are there any ENGINE BATTERY OR CHARGING SYSTEM DTC's present?
NO: Go to 2
YES: Refer to symptom list for problems related to ENGINE.
2. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Start the engine and run for 2 minutes.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTC's.
Q: Does the scan tool display BATTERY VOLTAGE LOW in the Sunroof module only?
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. (A932) FUSED B(+) CIRCUIT RESISTED
Turn the ignition off.
Lower the headliner and disconnect the Sunroof Motor/Module connector.
Test for a resisted (A932) Fused B(+) circuit by connecting a 12-volt test light between the (A932) Fused B(+) circuit and the (Z914) Ground circuit in the Sunroof Motor/Module connector. The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
Q: Does the test light illuminate brightly?
YES: Replace the Sunroof Motor/Module.
Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Test the (A932) Fused B(+) and the (Z914) Ground circuits to determine which circuit is resisted. Repair the (A932) Fused B(+) circuit or the (Z914) Ground circuit for high resistance.
