Pinpoint Test B: Adjustable Brake Pedal is Inoperative/Does Not Operate Correctly - Using the Adjustable Pedal Switch (System With Memory Feature)
Refer to Adjustable Pedal for schematic and connector information.

Normal Operation
The adjustable pedal switch receives fused battery voltage from smart junction box (SJB) fuse 27 (20A) along circuit SBP27 (BN/RD).

When the adjustable pedal switch is placed in the forward position, voltage is sent to the driver seat module (DSM) along circuit CPP09 (VT/OG), the DSM then sends the voltage to the adjustable pedal motor along circuit CPP09 (VT/OG), the voltage passes through the motor and returns to the DSM along circuit CPP10 (BN/BU). The DSM then sends the voltage back to the switch along circuit CPP10 (BN/BU) where it is grounded along circuit GD111 (BK/BU). This causes the pedal to move forward (away from the driver).

When the adjustable pedal switch is placed in the forward position, voltage is sent to the DSM along circuit CPP10 (BN/BU), the DSM then sends the voltage to the adjustable pedal motor along circuit CPP10 (BN/BU), the voltage passes through the motor and returns to the DSM along circuit CPP09 (VT/OG). The DSM then sends the voltage back to the switch along circuit CPP09 (VT/OG) where it is grounded along circuit GD111 (BK/BU). This causes the pedal to move rearward (toward the driver).
^ B1988 Pedal Position Forward Switch Circuit Short to Battery - If during normal operation, the DSM detects battery voltage on the adjustable pedal switch forward input circuit for more than 2 minutes DTC B1988 will be set. If during the DSM on-demand self test, the DSM detects voltage on the adjustable pedal switch forward input circuit at all, DTC B1988 will be set.
^ B1989 Pedal Position Rearward Switch Circuit Short to Battery - If during normal operation, the DSM detects battery voltage on the adjustable pedal switch rearward input circuit for more than 2 minutes DTC B1989 will be set. If during the DSM on-demand self test, the DSM detects voltage on the adjustable pedal switch rearward input circuit at all, DTC B1989 will be set.

This pinpoint test is intended to diagnose the following:
^ Foreign material
^ Fuse
^ Wiring, terminals or connectors
^ Adjustable pedal switch
^ Adjustable pedal potentiometer
^ Adjustable pedal motor
