Measure: LH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C521-8 - RH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C626-8 - Is the voltage greater than 11 volts? Yes: GO to I7 No: GO to I5
  5. I5 CHECK THE PUDDLE LAMP VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND Ignition OFF. Disconnect: DDM C501B (left puddle lamp). Disconnect: PDM C652B (right puddle lamp). Measure: LH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C521-8 ohms - RH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C626-8 ohms - Is the resistance greater than 10, 000 ohms? Yes: GO to I6 No: REPAIR the circuit.
  6. I6 CHECK THE PUDDLE LAMP VOLTAGE SUPPLY CIRCUIT FOR AN OPEN Measure: LH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C521-8 ohms C501B-6 RH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C626-8 ohms C652B-6 Is the resistance less than 3 ohms? Yes: INSTALL a new door module in question. REFER to: «DOOR MODULE»(ref-515973-S26456212192012120400000) . No: REPAIR the circuit.
  7. I7 CHECK THE EXTERIOR MIRROR GROUND CIRCUIT Measure: LH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C521-8 C521-6 RH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C626-8 C626-6 Is the voltage greater than 11 volts? Yes: INSTALL a new exterior mirror. REFER to: «REAR VIEW MIRRORS»(ref-516026-S04058834522012120400000) (Vehicles Without: One-Touch Up Door Window) . No: GO to I8
  8. I8 CHECK THE PUDDLE LAMP GROUND CIRCUIT FOR AN OPEN Ignition OFF. Disconnect: DDM C501B (left puddle lamp). Disconnect: PDM C652B (right puddle lamp). Measure: LH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C521-6 ohms C501B-18 RH EXTERIOR MIRROR Positive Lead Measurement / Action Negative Lead C626-6 ohms C652B-18 Is the resistance less than 3 ohms? Yes: INSTALL a new door module in question. REFER to: «DOOR MODULE»(ref-515973-S26456212192012120400000) . No: REPAIR the circuit.
