DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DIGITAL TRANSMISSION RANGE (DTR) SENSOR CIRCUIT FAILURE
CAUTION: DO NOT PRY on connector. This will damage the
•
connector and result in a motor/transaxle concern.
With key OFF, disconnect DTR sensor C4996 and inspect both ends of
the connector for damage or pushed out pins, corrosion, loose wires, and
missing or damaged seals.
• Is there damage to the connector, pins, or harness?
A3 CHECK ELECTRICAL SYSTEM OPERATION FOR DTR
SENSOR AND TRACTION INVERTER MODULE (TIM)
• With key OFF, reconnect DTR sensor C4996.
• Monitor the TIM PID TRANSGR.
• Shift the transmission range selector lever into each gear and stop.
• Observe the TRANSGR PID while wiggling harness and tapping on
sensor.
• Does the TRANSGR PID match the selected gear and does the
TRANSGR PID remain steady when the harness is wiggled or when
the sensor is tapped?
A4 CHECK DTR SENSOR OPERATION
• With key OFF, disconnect DTR sensor C4996.
• Connect TR-E Cable to Transmission Tester and DTR sensor.
• Place the Digital TR Sensor Overlay onto Transmission Tester.
NOTE: The D/2 status lamp on TR-E Cable should illuminate when the
transmission range selector lever is moved to the ECONOMY position.
• Carry out Sensor Test as instructed on Digital TR Sensor Overlay.
• Does the status lamp on TR-E Cable match the selected gear positions?
A5 CHECK TR1 INPUT SIGNAL STATUS
• With key OFF, reconnect DTR sensor C4996.
• With key ON, monitor TIM PID PRNDE 1.
• With brake pedal depressed, shift the transmission range selector lever
through all gears and back to PARK.
• Compare PRNDE 1 PID to the values below:
PARK = ACTIVE
REVERSE = ACTIVE
NEUTRAL = ACTIVE
DRIVE = notACT
ECONOMY = notACT
• Is the PRNDE 1 PID correct?
A6 CHECK CIRCUIT 3500 (R) FOR OPEN
• 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 OFF, disconnect DTR sensor C4996 and measure the resistance No =
of the R wire between pin 4 on the DTR sensor C4996 and BOB pin B7.
• Is the resistance less than 5 ohms?
A7 CHECK CIRCUIT 3500 (R) FOR SHORT TO POWER
(Continued)
Automatic Transaxle External Controls
TEST STEP ACTION TO TAKE
No = GO to A3.
Yes = System OK.
No = If TRANSGR PID changes
when wiggling the harness
or tapping on the sensor, the
concern may be intermittent.
GO to A4.
Yes = The concern is not in the
DTR sensor. REMOVE
Transmission Tester and
TR-E Cable. GO to A5.
No = REPLACE the DTR sensor
and ALIGN; REFER to
Digital Transmission Range
(DTR) Sensor Alignment in
this section.
GO to A9.
Yes =
No = If all gears indicate notACT,
GO to A6.
If all gears indicate
ACTIVE, GO to A8.
Yes = GO to A7.
REPAIR the R wire.
