PINPOINT TEST A: DTC C1446 BRAKE SWITCH CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
A1 CHECK BRAKE SWITCH STATUS
•
With key ON, monitor the traction inverter module (TIM) PID Yes = GO to A5.
BOO TIM while depressing the brake pedal.
•
Does the BOO TIM PID indicate OFF with the brake pedal not
No = GO to A2.

A2 CHECK FUSE AND POWER TO BRAKE PEDAL POSITION
(BPP) SWITCH
•
With key OFF, check 10A fuse 13 in the I/P fuse panel. Yes = RECONNECT the BPP
switch. GO to A3.
•
With key OFF, disconnect BPP switch C210 and measure the voltage No = REPAIR as necessary.
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 Yes = REPLACE the TIM. REFER
BCM/TIM BOB Adapter Cable and Overlay; leave the TIM to Section 303-14.
disconnected.
•
With key ON, measure the voltage between BOB pin B14 and ground No = GO to A4.
(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 Yes = REPLACE the BPP switch.
of the R/LG wire between pin 4 on BPP switch C210 and BOB pin 14.
•
Is the resistance less than 5 ohms?
No = REPAIR the R/LG wire.
