Diagnostic Test

FUSED B+ CIRCUIT OPEN
NOTE: Check all fuses and circuit breakers before proceeding with the diagnosis of this DTC.
1. Turn the ignition on.
2. Remove the Rear Wiper relay.
3. Measure the voltage at cavity 86 of the Rear Wiper relay.
  Is the voltage above 10.0 volts?
  
  Yes
  - Go to step 2
  No
  - Check the Fused B+ circuit for an open.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure

  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
(W12) REAR WIPER RELAY CONTROL CIRCUIT SHORT TO GROUND
1. Measure the resistance between ground and the (W12) Rear Wiper Relay Control circuit.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Repair the (W12) Rear Wiper Relay Control circuit for a short to ground.
  - Perform the BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure
  No
  - Go to step 4
