CIRCUIT DESCRIPTION
The rear side door actuator control module is capable of performing diagnostics. The rear side door actuator control module sounds Diagnostic Trouble Codes (DTCs) through the power sliding door alarm when the Diagnostic Mode 1 is active. The rear side door actuator control module will not enter the Diagnostic Mode 1 when the power sliding door alarm is faulty or no power or ground is provided to the rear side door actuator control module.
DIAGNOSTIC AIDS
^ An Intermittent failure may be difficult to detect and to accurately diagnose. Faulty electrical connections or wiring causes most Intermittent problems. When an Intermittent condition is suspected, inspect the suspected circuits for the following conditions:
- Poor mating of connector halves
- Backed out terminals
- Improperly formed or damaged terminals
- Wire chafing
- Poor wire-to-terminal connections
- Dirty or corroded terminals
- Damaged connector bodies
- A broken wire inside the insulation
^ Use a J 35616-A whenever a diagnostic procedure requests probing or inspecting a terminal. Using the J 35616-A ensures that no damage to the terminal will occur. Using the J 35616-A provides an estimate of whether the contact tension is sufficient.
