April 5, 2026: LEMON Manuals is launched! Read the announcement.

Possible Causes

Circuit open
Circuit shorted
Instrument cluster
ABS module

CAUTION:

Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

DTC C1414 - INCORRECT MODULE DESIGN LEVEL - PINPOINT TEST REFERENCE

PINPOINT TEST 7		DTC C1414 - INCORRECT MODULE DESIGN LEVEL
STEP	INSPECTION		ACTION
1	CHECK THE 4WD STATUS CIRCUIT AT THE ABS MODULE Verily the correct operation of the 4WD. If the 4WD is not operating correctly it must be repaired before proceeding. See TRANSFER CASE ELECTRONIC SHIFT ON - BOARD DIAGNOSIS , . Key OFF. Disconnect: Instrument cluster connector. Measure the voltage between the instrument cluster circuit (G/V), harness side and ground. Is the voltage greater than 10 volts?	Yes	Go to next step.
1		No	Go to step 3.
2	CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION Disconnect all instrument cluster connectors. Check for: corrosion. pushed-out pins. spread terminals. Connect all instrument cluster connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	Install a new instrument cluster. see INSTRUMENT CLUSTER .
2		No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test with the brake pedal not applied.
3	CHECK CIRCUIT (G/V) FOR AN OPEN Key OFF. Disconnect: ABS control module connector. Measure the resistance between ABS module circuit (G/V), harness side and instrument cluster circuit (G/V) harness side. Is the resistance less than 5 ohms?	Yes	Go to next step.
3		No	Repair circuit (GA/) for an open. Clear the DTCs. Repeat the self-test with the brake pedal not applied.
4	CHECK CIRCUIT (GA/) FOR A SHORT TO GROUND Measure the resistance between the ABS module circuit (GA/) harness side and ground. Is the resistance greater than 10,000 ohms?	Yes	Go to next step.
4		No	Repair circuit (G/V) for a short to ground. Clear the DTCs. Repeat the self-test with the brake pedal not applied.
5	CHECK CIRCUIT (G/V) FOR A SHORT TO POWER Key ON. Measure the voltage between the ABS module circuit (G/V), harness side and ground. Is there any voltage present?	Yes	Repair circuit (LB) for a short to voltage. Clear the DTCs. Repeat the self-test with the brake pedal not applied.
5		No	Go to next step.
6	CHECK FOR CORRECT ABS MODULE OPERATION Disconnect all ABS connector. Check for: corrosion. pushed-out pins. spread terminals. Connect all ABS connector and make sure it is seated correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	Install a new ABS module. see ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . Test the system for normal operation.
6		No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test with the brake pedal not applied.
