DTC 19 Inside Mirror Circuit (Inside Rear View Mirror With Memory) (Part 2 Of 2):

CIRCUIT DESCRIPTION
The driver seat adjuster memory module monitors the voltage of the inside rear view mirror motor and potentiometer circuits using terminals 8 and 9 of the driver seat adjuster memory module connector C2. The normal voltage reading should be between .14 V-4.67 V. If the voltage reading is not in the normal range, the driver seat adjuster memory module sets DTC 19.

CONDITIONS FOR SETTING THE DTC
DTC 19 will set if:
^ there is a short to B+ in any of the circuits related to terminals 8 and 9 of the driver seat adjuster memory module connector C2.
^ there is a short to ground or an open in any of the circuits related to terminals 8 and 9 of the driver seat adjuster memory module connector C2.
^ there is a failure within the inside rear view mirror potentiometer.
^ there is an internal failure within the driver seat adjuster memory module.

ACTION TAKEN WHEN THE DTC SETS
^ The driver seat adjuster memory module will store DTC 19.
^ The automatic adjustment of the inside rear view mirror is blocked.
^ The adjustment speed of the inside rear view mirror motors is not monitored (i.e. blocking end of the affected motor is not recognized).
^ The end stops of the inside rear view mirror motors is not monitored (i.e. the affected motor is not switched off when it reaches its programmed end stop).
^ The position of the motor is not stored in the driver seat adjuster memory module.

CONDITIONS FOR CLEARING THE DTC
^ DTC 19 will clear when the conditions for the fault are no longer present.
^ DTC 19 can be cleared by using the scan tool.

DIAGNOSTIC AIDS
^ Check for an open, high resistance, short to ground or short to B+ in circuits RB60.
^ Check for an open, high resistance, short to ground or short to B+ in circuits RF70.
^ Check for loose connections and damaged connectors.

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks the voltage on circuit R70.
4. This step checks the voltage on circuit RU60.
6. This step replaces the RH outside rear view mirror.
