This feature allows the operator to simultaneously retract both mirrors to a fully folded position. The driver door switch assembly (DDSA) contains the power folding mirrors switch and, each mirror contains an additional power folding mirror motor. The DDSA sends a class 2 serial data message to the passenger door module (PDM) when the power folding mirror switch is activated to the retract or extend positions. When the PDM detects an active power folding mirror command from the DDSA, the PDM responds by applying battery voltage and ground to the appropriate power folding mirror control circuits of both the driver and passenger power folding mirror motors in order to retract or extend both mirrors. When the switch is activated to unfold the mirrors, the PDM reverses the polarity of the voltage and ground applied to the motors in order to move both mirrors to the fully extended position.

⇒ | If the parameter does not cycle between the specified values, replace the DDSA. |
⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the passenger door module. |
⇒ | If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the passenger door module. |
⇒ | If the test lamp remains OFF during either of the commands, test for a short to ground on either control circuit. If the circuit tests normal, replace the passenger door module. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
⇒ | If the test lamp remains OFF during the command, test for a short to ground or an open/high resistance on the control circuit. |
⇒ | If the test lamp remains OFF during the command, test for a short to ground or an open/high resistance on the control circuit. |
⇒ | If the test lamp remains OFF during either of the commands, test for a short to ground or an open/high resistance on either control circuit. If the circuits test normal, replace the appropriate F/MIR relay. |
