U1408-IMPLAUSIBLE BRAKE SIGNAL RECEIVED
Theory of Operation

The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID.

• When Monitored:

• Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN Bus Off Performance DTC present.
• Set Condition: When the TCM detects an incorrect CAN ID from the ABS control module.

Possible Causes
FCM CAN BUS DTC'S PRESENT
ABS DTC'S PRESENT
TRANSMISSION CONTROL MODULE




U0002-CAN C BUS OFF PERFORMANCE

• When Monitored: With the ignition on.
• Set Condition: The FCM detects a short in either CAN C Bus circuit.

Possible Causes
(D65) CAN C BUS (+) CIRCUIT SHORTED TO GROUND
(D64) CAN C BUS (-) CIRCUIT SHORTED TO GROUND
(D65) CAN C BUS (+) CIRCUIT SHORTED TO VOLTAGE
(D64) CAN C BUS (-) CIRCUIT SHORTED TO VOLTAGE
(D65) CAN C BUS (+) CIRCUIT SHORTED TO (D64) CAN C BUS (-) CIRCUIT
ANTILOCK BRAKE MODULE
POWERTRAIN CONTROL MODULE
SHIFTER LEVER ASSEMBLY (NAG1 ONLY)
TRANSMISSION CONTROL MODULE (NAG1 ONLY)
STEERING CONTROL MODULE
FRONT CONTROL MODULE




B1668-REVERSE LAMP CONTROL CIRCUIT HIGH

• When Monitored:
• Continuously
• Set Condition:

• When the Front Control Module detects a short to battery on the Control circuit.

Possible Causes
(L1) BACKUP LAMPS CONTROL CIRCUIT
REVERSE LAMP
POWER DISTRIBUTION CENTER
FRONT CONTROL MODULE





U1107-ECU IN SINGLE-WIRE MODE

• When Monitored: With the ignition on.
• Set Condition: The FCM detects an open, a short high, a short low or a short together in either of the CAN B Bus circuits.

Possible Causes
(D55) CAN B BUS (+) CIRCUIT SHORTED TO GROUND
(D54) CAN B BUS (-) CIRCUIT SHORTED TO GROUND
(D55) CAN B BUS (+) CIRCUIT SHORTED TO VOLTAGE
(D54) CAN B BUS (-) CIRCUIT SHORTED TO VOLTAGE
(D55) CAN B BUS (+) CIRCUIT SHORTED TO (D54) CAN B BUS (-) CIRCUIT
(D55) CAN B BUS (+) CIRCUIT OPEN
(D54) CAN B BUS (-) CIRCUIT OPEN
ANY CAN B BUS MODULE



U0019-CAN B BUS

• When Monitored: With the ignition on.
• Set Condition: The FCM detects an open, a short high, a short low or a short together in either of the CAN B Bus circuits.

Possible Causes
(D55) CAN B BUS (+) CIRCUIT OPEN
(D54) CAN B BUS (-) CIRCUIT OPEN
(D55) CAN B BUS (+) CIRCUIT SHORTED TO VOLTAGE
(D54) CAN B BUS (-) CIRCUIT SHORTED TO VOLTAGE
(D55) CAN B BUS (+) CIRCUIT SHORTED TO GROUND
(D54) CAN B BUS (-) CIRCUIT SHORTED TO GROUND
(D55) CAN B BUS (+) CIRCUIT SHORTED TO (D54) CAN B BUS (-) CIRCUIT
ANY CAN B BUS MODULE
