PINPOINT TEST A: DTC C1446 BRAKE SWITCH CIRCUIT FAILURE
A1 CHECK BRAKE SWITCH STATUS
• With key ON, monitor the traction inverter module (TIM) PID
BOO TIM while depressing the brake pedal.
• Does the BOO TIM PID indicate OFF with the brake pedal not
depressed and ON with the brake pedal depressed?
A2 CHECK FUSE AND POWER TO BRAKE PEDAL POSITION
(BPP) SWITCH
• With key OFF, check 10A fuse 13 in the I/P fuse panel.
• With key OFF, disconnect BPP switch C210 and measure the voltage
between pin 3 (LG/R wire) on BPP switch C210 and ground. (V > 10
volts)
• Is everything OK?
A3 CHECK BPP SWITCH SIGNAL TO TIM
• Connect 104-Pin Breakout Box (BOB) to TIM C4998, C4999 using the
BCM/TIM BOB Adapter Cable and Overlay; leave the TIM
disconnected.
• With key ON, measure the voltage between BOB pin B14 and ground
(BOB pin A29) with the brake pedal depressed.
• Is the voltage greater than 10 volts?
A4 CHECK CIRCUIT 810 (R/LG) FOR OPEN
• With key OFF, disconnect BPP switch C210 and measure the resistance
of the R/LG wire between pin 4 on BPP switch C210 and BOB pin 14.
• Is the resistance less than 5 ohms?
